1 00:00:00,000 --> 00:00:05,000 In a remote fishing village in Nova Scotia, 2 00:00:05,000 --> 00:00:08,000 local residents witnessed lights crashing into the harbor. 3 00:00:08,000 --> 00:00:12,000 At first, they assume a plane has gone down, 4 00:00:12,000 --> 00:00:15,000 but government documents reveal a shocking alternative. 5 00:00:15,000 --> 00:00:18,000 No one reported a UFO. 6 00:00:18,000 --> 00:00:20,000 One of the unique things of this case, 7 00:00:20,000 --> 00:00:23,000 it was the authorities that were openly calling it that. 8 00:00:26,000 --> 00:00:28,000 In Iran, the Air Force scrambles fighters 9 00:00:28,000 --> 00:00:31,000 to investigate strange lights in the sky, 10 00:00:31,000 --> 00:00:35,000 leading to an astonishing mid-air encounter. 11 00:00:35,000 --> 00:00:38,000 These projectiles were heading directly for his aircraft, 12 00:00:38,000 --> 00:00:40,000 and he didn't know what to do. 13 00:00:44,000 --> 00:00:46,000 And in New Zealand, several witnesses 14 00:00:46,000 --> 00:00:49,000 see an object streak across the sky. 15 00:00:49,000 --> 00:00:51,000 I cannot categorize what it was. 16 00:00:51,000 --> 00:00:53,000 It was something I have never seen. 17 00:00:53,000 --> 00:00:55,000 These mysterious sightings spark an investigation 18 00:00:55,000 --> 00:00:58,000 with some remarkable conclusions. 19 00:00:58,000 --> 00:01:01,000 It actually climbed, and it increased in speed. 20 00:01:01,000 --> 00:01:04,000 It was operating in some kind of controlled manner. 21 00:01:06,000 --> 00:01:09,000 Does anyone know what these phenomena are? 22 00:01:09,000 --> 00:01:11,000 And do the governments of the world 23 00:01:11,000 --> 00:01:14,000 know more than they ever revealed to us? 24 00:01:14,000 --> 00:01:18,000 The answers may lie in the fascinating stories 25 00:01:18,000 --> 00:01:21,000 of UFO conspiracies. 26 00:01:25,000 --> 00:01:28,000 October 4, 1967. 27 00:01:28,000 --> 00:01:30,000 Nova Scotia, Canada. 28 00:01:30,000 --> 00:01:32,000 In a suburb of Halifax, 29 00:01:32,000 --> 00:01:35,000 local resident Chris Stiles, then 12 years old, 30 00:01:35,000 --> 00:01:37,000 is at home. 31 00:01:37,000 --> 00:01:39,000 At about 10.30 p.m., 32 00:01:39,000 --> 00:01:42,000 I was getting ready for bed on a school night. 33 00:01:42,000 --> 00:01:44,000 I was up late as usual, 34 00:01:44,000 --> 00:01:47,000 and I happened to look out the back window of my house. 35 00:01:47,000 --> 00:01:49,000 And when I looked in that direction, 36 00:01:49,000 --> 00:01:53,000 I saw an orange sphere that was dull, 37 00:01:53,000 --> 00:01:56,000 quite large, moving along the coastline. 38 00:01:56,000 --> 00:01:59,000 And I knew right away that I was seeing something very strange, 39 00:01:59,000 --> 00:02:01,000 and I wanted a better look. 40 00:02:01,000 --> 00:02:03,000 Chris runs out of the house 41 00:02:03,000 --> 00:02:06,000 and down to the waterfront as fast as he can. 42 00:02:06,000 --> 00:02:09,000 I was confronted with a 60-foot orange ore 43 00:02:09,000 --> 00:02:13,000 that was hovering silently low over the water. 44 00:02:13,000 --> 00:02:15,000 It was absolutely featureless, 45 00:02:15,000 --> 00:02:18,000 and the texture of it would remind one of iron 46 00:02:18,000 --> 00:02:20,000 when it first glowed in a fire. 47 00:02:20,000 --> 00:02:23,000 I'm looking at this thing, and I'm just overwhelmed with fear. 48 00:02:23,000 --> 00:02:27,000 Eventually, I seemed to find the courage to run, 49 00:02:27,000 --> 00:02:30,000 and this unusual object paid no attention to me whatsoever 50 00:02:30,000 --> 00:02:33,000 and just continued on its way. 51 00:02:33,000 --> 00:02:37,000 This brief encounter changes Chris' life forever. 52 00:02:37,000 --> 00:02:39,000 It sets him on a lifelong quest 53 00:02:39,000 --> 00:02:41,000 to discover what really happened 54 00:02:41,000 --> 00:02:43,000 off the coast of Canada that night. 55 00:02:43,000 --> 00:02:47,000 You start to think that everything you've been told is wrong. 56 00:02:47,000 --> 00:02:50,000 And even as a boy of 12, you knew you were being lied to. 57 00:02:50,000 --> 00:02:52,000 Answers were few and far between, 58 00:02:52,000 --> 00:02:54,000 and it was unsettling. 59 00:02:54,000 --> 00:02:57,000 It was like a bad dream. 60 00:03:01,000 --> 00:03:04,000 Decades later, Chris' research would lead him to a place 61 00:03:04,000 --> 00:03:09,000 160 miles to the south, called Shag Harbor. 62 00:03:09,000 --> 00:03:12,000 There, he would learn that a similar drama unfolded 63 00:03:12,000 --> 00:03:16,000 at exactly the same time of his own UFO encounter. 64 00:03:21,000 --> 00:03:24,000 It begins with an 18-year-old fisherman, Lori Wickens, 65 00:03:24,000 --> 00:03:28,000 who was driving through Shag Harbor after an evening out with friends. 66 00:03:28,000 --> 00:03:31,000 Lori still lives in Shag Harbor, 67 00:03:31,000 --> 00:03:34,000 and he's never forgotten the events of that night. 68 00:03:34,000 --> 00:03:37,000 Ralphie read along here somewhere that we first noticed 69 00:03:37,000 --> 00:03:40,000 the lights in the sky that night. 70 00:03:42,000 --> 00:03:45,000 First one would come on, two, three, and four, 71 00:03:45,000 --> 00:03:49,000 then they would all go out and start over in that same signal. 72 00:03:49,000 --> 00:03:51,000 It seemed like they were in a line, 73 00:03:51,000 --> 00:03:53,000 and it didn't seem to be that far away. 74 00:03:53,000 --> 00:03:56,000 As Lori drives along the Bering Coastal Highway, 75 00:03:56,000 --> 00:03:59,000 the lights appear to track with him for several miles. 76 00:03:59,000 --> 00:04:02,000 Couldn't have known engines or no noise from it. 77 00:04:02,000 --> 00:04:04,000 We got along here somewhere. 78 00:04:04,000 --> 00:04:07,000 It seemed like it turned down on a 45-degree angle. 79 00:04:07,000 --> 00:04:10,000 The lights seemed to be coming down towards the water. 80 00:04:10,000 --> 00:04:14,000 Lori loses sight of the object as it dips below the treeline. 81 00:04:14,000 --> 00:04:16,000 Then... 82 00:04:16,000 --> 00:04:19,000 it crashes into the ocean. 83 00:04:21,000 --> 00:04:23,000 Believing a plane has crashed, 84 00:04:23,000 --> 00:04:26,000 Lori drives as fast as he can to the nearest phone booth 85 00:04:26,000 --> 00:04:30,000 to call the RCMP, the Royal Canadian Mounted Police. 86 00:04:32,000 --> 00:04:36,000 They initially dismissed the call as a hoax. 87 00:04:37,000 --> 00:04:39,000 Fortunately, Lori had a local reputation operating 88 00:04:39,000 --> 00:04:41,000 and asked him if he had been drinking, and he said, 89 00:04:41,000 --> 00:04:43,000 No, I am not. 90 00:04:43,000 --> 00:04:45,000 He said, You guys better get down here. 91 00:04:45,000 --> 00:04:47,000 There's something out there on the water. 92 00:04:47,000 --> 00:04:49,000 And they said, OK, they look into it. 93 00:04:51,000 --> 00:04:53,000 The moment the police hang up on him, 94 00:04:53,000 --> 00:04:57,000 several other calls come through describing similar events. 95 00:04:59,000 --> 00:05:01,000 No one reported a UFO. 96 00:05:01,000 --> 00:05:04,000 Those who called the police said simply 97 00:05:04,000 --> 00:05:07,000 that they'd seen lights, or perhaps a large aircraft 98 00:05:07,000 --> 00:05:09,000 would crash into the sound. 99 00:05:09,000 --> 00:05:11,000 The concern was for survivors. 100 00:05:19,000 --> 00:05:22,000 This is where we told the RCMP to meet us, 101 00:05:22,000 --> 00:05:25,000 so we could see the light in the water after I'd been to the phone booth 102 00:05:25,000 --> 00:05:28,000 and called them, and that's where we first see it in the water. 103 00:05:28,000 --> 00:05:33,000 Then it was down there, and we watched it drift the whole way down by a harbor here. 104 00:05:35,000 --> 00:05:38,000 Just one light, like half of a globe upside down, 105 00:05:38,000 --> 00:05:40,000 sitting on the water. 106 00:05:40,000 --> 00:05:43,000 It was a yellowish-white light that was on steady. 107 00:05:45,000 --> 00:05:48,000 The RCMP arrived, and, like Lori and the other witnesses, 108 00:05:48,000 --> 00:05:52,000 catch sight of the mysterious object floating in the water. 109 00:05:53,000 --> 00:05:55,000 We just figured it was a plane in the water. 110 00:05:55,000 --> 00:05:58,000 We was going to look for rackets or people or whatever. 111 00:05:59,000 --> 00:06:01,000 Then the light vanishes. 112 00:06:02,000 --> 00:06:04,000 It just went out. Just disappeared. 113 00:06:04,000 --> 00:06:07,000 It didn't stay on and go into the water. You'd notice it. The light just went out. 114 00:06:08,000 --> 00:06:10,000 Desperate to find any survivors, 115 00:06:10,000 --> 00:06:13,000 the police commandeered some local fishing boats, 116 00:06:13,000 --> 00:06:16,000 while the Coast Guard sent their own rescue vessel to Shag Harbor. 117 00:06:17,000 --> 00:06:19,000 Lori joins the rescue flotilla. 118 00:06:20,000 --> 00:06:24,000 We went out looking for the harbor everywhere for debris, and we never found none. 119 00:06:25,000 --> 00:06:28,000 All that is found is a strange foam on the surface of the water. 120 00:06:28,000 --> 00:06:31,000 It was yellow. Some of them claimed it was melt-solve. 121 00:06:31,000 --> 00:06:33,000 First, some said they did not smell anything. 122 00:06:33,000 --> 00:06:36,000 There was an attempt to collect some of it at the time. 123 00:06:36,000 --> 00:06:38,000 We used a fine dip net, 124 00:06:38,000 --> 00:06:41,000 but as you collected the foam, it would simply dissipate, and nothing remained. 125 00:06:43,000 --> 00:06:45,000 The search resumes at first light, 126 00:06:45,000 --> 00:06:49,000 but there is no sign of any plane or anything else. 127 00:06:50,000 --> 00:06:54,000 Canadian Forces headquarters eventually orders an underwater search by maritime command. 128 00:06:54,000 --> 00:06:56,000 And this went on for several days. 129 00:06:56,000 --> 00:07:01,000 At last light on Sunday, this search was terminated, reporting new results. 130 00:07:03,000 --> 00:07:05,000 As far as all the locals are concerned, 131 00:07:05,000 --> 00:07:08,000 the mysterious object is some sort of aircraft. 132 00:07:09,000 --> 00:07:14,000 But ironically, the government itself makes an outlandish claim. 133 00:07:14,000 --> 00:07:19,000 I think it was all about three days after I see an RCMP officer in Barrenton, the Bowling Islands, 134 00:07:19,000 --> 00:07:20,000 and you know what you see? 135 00:07:20,000 --> 00:07:22,000 I said, no, he's at the UFO. 136 00:07:23,000 --> 00:07:25,000 I said, what's that? Then he told me. 137 00:07:25,000 --> 00:07:27,000 So that's the first we'd ever heard of a UFO. 138 00:07:29,000 --> 00:07:32,000 This idea from the authorities quickly spreads, 139 00:07:32,000 --> 00:07:34,000 and the story explodes in the press. 140 00:07:36,000 --> 00:07:38,000 The Shag Harbor incident was front-page news. 141 00:07:38,000 --> 00:07:43,000 It quickly went into being a line story that was picked up around the world, 142 00:07:43,000 --> 00:07:46,000 received national coverage on CBC television. 143 00:07:47,000 --> 00:07:50,000 A comic book is even made depicting the events of that night. 144 00:07:52,000 --> 00:07:55,000 But despite the furor, the story is soon all but forgotten. 145 00:07:56,000 --> 00:08:00,000 The government inquiry is closed, the world moves on, 146 00:08:00,000 --> 00:08:03,000 and the people of Shag Harbor return to their lives. 147 00:08:04,000 --> 00:08:06,000 They look at this, they shrugged answers didn't come, said, 148 00:08:06,000 --> 00:08:09,000 I wonder what that was, went home, made a sandwich, life went on. 149 00:08:10,000 --> 00:08:15,000 But for Chris Stiles, the events of October 4th, 1967 never went away. 150 00:08:16,000 --> 00:08:20,000 The mysterious crash in Shag Harbor and his own UFO encounter that night 151 00:08:20,000 --> 00:08:22,000 continue to haunt him. 152 00:08:24,000 --> 00:08:28,000 More than 25 years later, he will launch his own investigation, 153 00:08:28,000 --> 00:08:30,000 which uncovers shocking evidence. 154 00:08:31,000 --> 00:08:33,000 While these things were occurring in Shag Harbor, 155 00:08:33,000 --> 00:08:35,000 and while there was a search there, 156 00:08:35,000 --> 00:08:37,000 there was a second simultaneous search. 157 00:08:37,000 --> 00:08:39,000 The public never knew about this. 158 00:08:45,000 --> 00:08:51,000 In Nova Scotia, Chris Stiles is investigating a mysterious incident from the late 1960s. 159 00:08:52,000 --> 00:08:55,000 The apparent crash of an unidentified craft 160 00:08:55,000 --> 00:08:58,000 into waters off the fishing village of Shag Harbor. 161 00:09:00,000 --> 00:09:02,000 He enlists the help of the police, 162 00:09:03,000 --> 00:09:07,000 he enlists the help of fellow Canadian researcher Don Ledger. 163 00:09:07,000 --> 00:09:09,000 And he said, you know, I'd like to write a book about that. 164 00:09:09,000 --> 00:09:11,000 He said, but I'm not very good with the King's English. 165 00:09:11,000 --> 00:09:14,000 And I said, well, I've done quite a bit of writing. 166 00:09:14,000 --> 00:09:15,000 So I said, I'll take a stab at it. 167 00:09:15,000 --> 00:09:19,000 So over the course of a year, I wrote up most of the story. 168 00:09:20,000 --> 00:09:23,000 Together, Chris and Don begin to search for evidence 169 00:09:23,000 --> 00:09:25,000 of what the authorities knew that night. 170 00:09:26,000 --> 00:09:30,000 Their starting point was the fact that the first suggestion that this was a UFO 171 00:09:30,000 --> 00:09:32,000 came from the government itself. 172 00:09:32,000 --> 00:09:34,000 No one reported a UFO. 173 00:09:34,000 --> 00:09:37,000 One of the unique things of this case, it was the authorities that responded 174 00:09:37,000 --> 00:09:40,000 that even early the next day, we're openly calling it that. 175 00:09:40,000 --> 00:09:45,000 The Chronicle Herald and here in Halifax, the biggest newspaper this side of Montreal, 176 00:09:45,000 --> 00:09:49,000 had the banner head lined up, maybe something concrete to UFO crash 177 00:09:49,000 --> 00:09:51,000 in Shag Harbor in red block letters. 178 00:09:53,000 --> 00:09:56,000 Armed with this knowledge, they begin a detailed search 179 00:09:56,000 --> 00:09:58,000 through the archives for the source of the UFO claim. 180 00:09:59,000 --> 00:10:02,000 What you're looking for in the UFO cases in an investigator is two things. 181 00:10:02,000 --> 00:10:05,000 You're looking for high strangeness and high credibility. 182 00:10:05,000 --> 00:10:08,000 And when you get a paper trail like the Shag Harbor incident, 183 00:10:08,000 --> 00:10:13,000 you've got something in your hands that just won't go away or evaporate. 184 00:10:14,000 --> 00:10:18,000 One of the first documents they uncover appears to be a smoking gun. 185 00:10:20,000 --> 00:10:23,000 We look at the tellyx they send back when they order the underwater search. 186 00:10:23,000 --> 00:10:24,000 And what does it have? 187 00:10:24,000 --> 00:10:29,000 UFO, three big letters, underlined. 188 00:10:29,000 --> 00:10:34,000 And I've looked at thousands of these documents, but I've only seen one that was like that. 189 00:10:35,000 --> 00:10:41,000 This early, intriguing discovery spurs them on, and soon they uncover more. 190 00:10:42,000 --> 00:10:45,000 There were no aircraft missing anywhere that they could determine, 191 00:10:45,000 --> 00:10:50,000 up the east coast of Canada or down in the New England area in the United States. 192 00:10:50,000 --> 00:10:55,000 Each piece of evidence Chris and Don find seems to reinforce their theory. 193 00:10:56,000 --> 00:11:00,000 The Rescue Coordination Center conducted a preliminary investigation, 194 00:11:00,000 --> 00:11:09,000 and it's discounted the possibility that this sighting was produced by an aircraft, flare, float, or any other known object. 195 00:11:10,000 --> 00:11:13,000 The government of the day and the people that were investigating it 196 00:11:13,000 --> 00:11:16,000 didn't think that there was a conventional explanation possible. 197 00:11:17,000 --> 00:11:21,000 But the trail of evidence in the paperwork soon goes cold. 198 00:11:24,000 --> 00:11:28,000 Yet Chris is convinced there is more to the story. 199 00:11:28,000 --> 00:11:34,000 He started bumping into people who were a military or ex-military that had somehow been involved in this. 200 00:11:35,000 --> 00:11:38,000 Many of the people Chris meets are former Navy divers. 201 00:11:40,000 --> 00:11:43,000 These contacts reveal something extraordinary. 202 00:11:44,000 --> 00:11:49,000 There was a second secret search about 30 miles up the coast from Shag Harbor, 203 00:11:49,000 --> 00:11:52,000 in another harbor called Shelburne. 204 00:11:53,000 --> 00:12:03,000 What I was told by divers and support personnel was that several ships held station over two UFOs that were sitting on the bottom. 205 00:12:04,000 --> 00:12:08,000 Now, Chris had not one UFO to investigate, but two. 206 00:12:09,000 --> 00:12:13,000 Could it be that they are linked to what was seen hitting the water at Shag Harbor? 207 00:12:14,000 --> 00:12:17,000 Maybe more than one object went into the harbor that night. 208 00:12:17,000 --> 00:12:22,000 If that's the case, it raises the question of how they ended up so far along the coast. 209 00:12:23,000 --> 00:12:28,000 One of Chris's naval sources has a shocking theory based on what he saw on the seabed, 210 00:12:29,000 --> 00:12:32,000 that the objects were moving under their own power. 211 00:12:33,000 --> 00:12:37,000 He said, well, you know, we saw things down there. 212 00:12:37,000 --> 00:12:41,000 It looked like one object was lending assistance to the other object. 213 00:12:41,000 --> 00:12:43,000 What could these objects be? 214 00:12:44,000 --> 00:12:47,000 There is no documentary evidence of the Shelburne search available, 215 00:12:47,000 --> 00:12:52,000 so Chris and Don have never established with certainty what was out there that night. 216 00:12:54,000 --> 00:12:58,000 One possibility is this incident is connected to the Cold War. 217 00:12:59,000 --> 00:13:07,000 In 1967, few people are aware that Shelburne is a secret front line in the struggle against the Soviet Union. 218 00:13:09,000 --> 00:13:14,000 The Shelburne base was Canada's most secret military installation. 219 00:13:14,000 --> 00:13:17,000 Initially, it was a U.S. base on Canadian soil. 220 00:13:18,000 --> 00:13:23,000 Its primary mission was to detect the movement of Soviet submarines during the height of the Cold War. 221 00:13:29,000 --> 00:13:34,000 It's no surprise that a UFO crash in close proximity to a critical naval defense 222 00:13:34,000 --> 00:13:39,000 would spark a strong response from the military at the height of Cold War tensions, 223 00:13:39,000 --> 00:13:44,000 especially if whatever went down was a valuable piece of military technology. 224 00:13:46,000 --> 00:13:50,000 Aviation historian Peter Merlin believes this is a possibility. 225 00:13:51,000 --> 00:13:57,000 In the late 1960s, the U.S. and Soviets were both developing advanced fighters and bombers. 226 00:13:58,000 --> 00:14:02,000 They were using high-altitude reconnaissance aircraft and spy satellites. 227 00:14:02,000 --> 00:14:07,000 If it was, in fact, U.S. technology that fell out of the sky, it's entirely possible 228 00:14:07,000 --> 00:14:10,000 the government would have wanted to recover it because it was either classified 229 00:14:10,000 --> 00:14:15,000 and they didn't want people to know, or simply to prevent embarrassment. 230 00:14:16,000 --> 00:14:23,000 One of the explanations that has come forth is that perhaps what was seen was a super-secret U.S. military device. 231 00:14:23,000 --> 00:14:27,000 I find this quite odd because if you're trying to test a new aircraft, 232 00:14:27,000 --> 00:14:30,000 you don't test it near a populated area. 233 00:14:30,000 --> 00:14:34,000 You certainly don't put flashing lights on it. You don't draw attention to it. 234 00:14:34,000 --> 00:14:38,000 Too many times these things are supposedly identified or people try to make them 235 00:14:38,000 --> 00:14:44,000 a military experimental aircraft, yet they're not doing what experimental military aircraft would do. 236 00:14:47,000 --> 00:14:52,000 If Don and Chris are right, if the objects seen in the sky and water off Nova Scotia 237 00:14:52,000 --> 00:14:57,000 are not aircraft, then there is a possibility they came from space. 238 00:14:58,000 --> 00:15:04,000 According to Dr. Alice Gorman, an expert in space debris, that doesn't make it an alien spacecraft, 239 00:15:04,000 --> 00:15:09,000 but part of a man-made one, a piece of so-called space junk. 240 00:15:09,000 --> 00:15:14,000 Even by the late 60s, there were at least a thousand objects in Earth orbit. 241 00:15:15,000 --> 00:15:20,000 We're looking at a lot of stuff that's up there and a lot of stuff with the potential to re-enter. 242 00:15:21,000 --> 00:15:26,000 What's more, it's not uncommon for pieces of space junk to survive re-entry. 243 00:15:27,000 --> 00:15:32,000 The most common object to re-enter and survive is actually titanium pressure spheres, 244 00:15:32,000 --> 00:15:34,000 which are part of the fuel injection system. 245 00:15:34,000 --> 00:15:40,000 A titanium pressure sphere very closely matches the description of the floating spherical object 246 00:15:40,000 --> 00:15:43,000 seen by Lori Wickens in the harbor that night. 247 00:15:43,000 --> 00:15:47,000 However, those close to the story discount this theory. 248 00:15:48,000 --> 00:15:52,000 That wasn't a meteorite or that wasn't space junk, it had been on fire and it wouldn't have been that color. 249 00:15:52,000 --> 00:15:56,000 It's unlikely to have been space junk, they would have known, they would have told us. 250 00:15:56,000 --> 00:16:00,000 The Canadian government was very forthcoming about such things happening here, 251 00:16:00,000 --> 00:16:08,000 and a great example occurred in the mid-70s when a Soviet satellite, nuclear-powered Cosmos 954, 252 00:16:08,000 --> 00:16:13,000 entered the atmosphere over the high Canadian Arctic and crashed 253 00:16:13,000 --> 00:16:16,000 and left a large footprint of radioactive debris. 254 00:16:16,000 --> 00:16:20,000 Everything was released to the public, they were very forthcoming and open about it. 255 00:16:20,000 --> 00:16:24,000 And I just think that if something similar had happened or had been responsible for this, 256 00:16:24,000 --> 00:16:30,000 that they would have had the same open policy in the 60s as they did a few years later in the 70s. 257 00:16:31,000 --> 00:16:35,000 One final explanation that has been put forward many times, 258 00:16:35,000 --> 00:16:41,000 suggests that the lights seen in the sky were nothing more sinister than a series of flares. 259 00:16:41,000 --> 00:16:45,000 The locals of this traditional fishing community scoff at that notion. 260 00:16:45,000 --> 00:16:50,000 Flare don't go flying through the air, it ain't four lines in a row, it goes up and it comes down, 261 00:16:50,000 --> 00:16:52,000 and either the bright red or it's white. 262 00:16:52,000 --> 00:16:56,000 And anybody that thinks that was a flare, I wouldn't want him to come rushing me. 263 00:16:57,000 --> 00:17:04,000 However, there are many different types of flares, and some of them do appear in rows, flying through the air. 264 00:17:05,000 --> 00:17:11,000 David Higgins, a helicopter pilot who has logged more than 8,000 flying hours, explains more. 265 00:17:11,000 --> 00:17:17,000 On the subject of flares, many military aircraft have the ability to deploy flares. 266 00:17:17,000 --> 00:17:23,000 And the purpose of these flares are to stave off heat seeking infrared missiles. 267 00:17:23,000 --> 00:17:27,000 They're mainly magnesium operating at thousands of degrees. 268 00:17:27,000 --> 00:17:30,000 Now the appearance of these flares are quite dramatic. 269 00:17:30,000 --> 00:17:39,000 They tend to burst out from the aircraft in an array, so it would give the appearance of being a string of lights. 270 00:17:40,000 --> 00:17:44,000 These kind of flares are often released as part of military exercises. 271 00:17:44,000 --> 00:17:47,000 But Don thinks this too is highly unlikely. 272 00:17:47,000 --> 00:17:51,000 Nobody was doing an exercise down around Shea Harbour, and why would they in the first place? 273 00:17:51,000 --> 00:17:53,000 That's not their normal exercise area. 274 00:17:53,000 --> 00:17:58,000 Flare said that's a pretty simple-minded explanation for something that's as complex as Shea Harbour. 275 00:18:00,000 --> 00:18:04,000 Decades later, mystery still surrounds the incident. 276 00:18:04,000 --> 00:18:11,000 Canada's Department of National Defense has officially stated that this sighting remains unsolved. 277 00:18:11,000 --> 00:18:16,000 I've already concluded that whatever was responsible for this that night has to be something unconventional. 278 00:18:16,000 --> 00:18:22,000 I'm not about to tell you that these are little grey guys from Zeta Reticuli or Alpha Centauri. I do not know. 279 00:18:22,000 --> 00:18:29,000 The lack of further government investigation indicates the events of that night may have been nothing extraordinary. 280 00:18:29,000 --> 00:18:34,000 Chris, however, will keep searching until he finds a definitive answer. 281 00:18:35,000 --> 00:18:40,000 I used to be very frustrated. I'm not anymore. I embrace the uncertainty of it now. I love it. 282 00:18:45,000 --> 00:18:50,000 September 18, 1976. Tehran, Iran. 283 00:18:51,000 --> 00:18:57,000 35-year-old Hussein Peruzzi is the night supervisor in the tower at Manorabad International Airport. 284 00:18:59,000 --> 00:19:03,000 At 10.30pm, he receives an unusual phone call. 285 00:19:04,000 --> 00:19:11,000 Peruzzi said that he received initially a call from a woman in the north of Tehran who reported seeing this brilliant object that looked too big to be a star. 286 00:19:11,000 --> 00:19:15,000 And her call was followed by three others from the same area of the city. 287 00:19:15,000 --> 00:19:18,000 When he had four calls, he knew that something was going on. 288 00:19:19,000 --> 00:19:25,000 The airport's radar system is down for maintenance. All he can try to do is make a visual identification. 289 00:19:25,000 --> 00:19:29,000 To his surprise, he too sees something in the sky. 290 00:19:30,000 --> 00:19:36,000 It was this brilliant flashing different-colored object that was moving, so he was very alarmed by that. 291 00:19:37,000 --> 00:19:44,000 Not knowing the identity of this fast-moving object, Peruzzi contacts the Iranian Air Force. They scramble a plane to investigate. 292 00:19:45,000 --> 00:19:51,000 175 miles away, a state-of-the-art American-made F-4 Phantom takes off. 293 00:19:52,000 --> 00:19:57,000 At the time of this incident, Iran's Islamic Revolution is more than two years away. 294 00:19:58,000 --> 00:20:04,000 Under the old regime of the Shah, Iran is a staunch ally of the United States against the Soviet Union. 295 00:20:05,000 --> 00:20:08,000 Aviation journalist Chris Polcock explains more. 296 00:20:09,000 --> 00:20:16,000 The U.S. and Iran had a close political and by extension military relationship before the fall of the Shah. 297 00:20:16,000 --> 00:20:28,000 And that included the supply by the U.S. of most of the equipment, aircraft, radars, missiles, and training of the Iranian Air Force. 298 00:20:29,000 --> 00:20:34,000 The Iranian F-4 races towards the location of the sightings at supersonic speed. 299 00:20:35,000 --> 00:20:41,000 They were able to get a good look at it as a very brilliant object with pulsing different-colored lights, almost like a strobe light. 300 00:20:42,000 --> 00:20:48,000 These F-4s were able to fly over a thousand miles an hour, and they were not able to catch up with this big UFO. 301 00:20:49,000 --> 00:20:55,000 By this time, the squadron commander, Parviz Jafari, has also taken to the skies in his own F-4. 302 00:20:56,000 --> 00:21:01,000 Now a retired Iranian Air Force general, Jafari still has vivid memories of that night. 303 00:21:02,000 --> 00:21:08,000 I called my first pilot. He said I can catch it with the supersonic speed. 304 00:21:08,000 --> 00:21:14,000 I lost all of my instruments and everything is abnormal. 305 00:21:15,000 --> 00:21:26,000 With the first fighter's electronic instruments disabled, Jafari fears the plane may stray into nearby Soviet airspace and turn a UFO encounter into an international crisis. 306 00:21:27,000 --> 00:21:29,000 He orders it to return to base. 307 00:21:30,000 --> 00:21:35,000 As soon as he returned back, he said I can see it again ahead of me. 308 00:21:36,000 --> 00:21:39,000 I said where is it? Can you give me a position? 309 00:21:40,000 --> 00:21:42,000 I looked there and I saw it. 310 00:21:45,000 --> 00:21:48,000 Jafari's initial sighting appears similar to the other reports. 311 00:21:49,000 --> 00:21:53,000 The shape was like a diamond shape like this. 312 00:21:53,000 --> 00:21:58,000 It was red, green, orange and blue. 313 00:21:59,000 --> 00:22:03,000 It was strobing in different colors and he said it was so bright that you couldn't actually see the body of the object. 314 00:22:04,000 --> 00:22:06,000 You could only see this very, very bright light. 315 00:22:07,000 --> 00:22:11,000 And like the first plane, Jafari has trouble catching up to this object. 316 00:22:12,000 --> 00:22:19,000 All of a sudden, it jumped about 10 degrees to my right, just like this. 317 00:22:19,000 --> 00:22:22,000 It was here, now it was here. 318 00:22:24,000 --> 00:22:29,000 At this point, Jafari's experience begins to radically depart from that of the first crew. 319 00:22:30,000 --> 00:22:32,000 He believes the object starts shooting at it. 320 00:22:33,000 --> 00:22:37,000 He called them projectiles. He said they look kind of like a full moon coming over the horizon. 321 00:22:38,000 --> 00:22:41,000 And these projectiles were heading directly for his aircraft. 322 00:22:42,000 --> 00:22:47,000 I was really scared. I thought they'd launched missiles or something. 323 00:22:50,000 --> 00:22:54,000 Fearing that he's about to be blown out of the sky, Jafari prepares to shoot back. 324 00:22:55,000 --> 00:22:59,000 When he was just about to fire at it, he lost control of his equipment. 325 00:23:00,000 --> 00:23:02,000 Everything went down. He was not able to fire at the missile. 326 00:23:03,000 --> 00:23:06,000 The only controls that remain are the ones keeping his aircraft in flight. 327 00:23:07,000 --> 00:23:12,000 With no weapons, Jafari tries to escape by pulling a radical turn away from the incoming projectile. 328 00:23:12,000 --> 00:23:23,000 He was able to make a turn and avoid it, and the thing then made some jumps and moved back into the main object. 329 00:23:24,000 --> 00:23:29,000 Jafari's commanders order him to break off and land in Tehran. 330 00:23:30,000 --> 00:23:34,000 As he's returning, another of the apparent projectiles appears behind him. 331 00:23:35,000 --> 00:23:39,000 He then sees it heading downwards towards a dry lake bed on the outskirts of the city. 332 00:23:39,000 --> 00:23:49,000 I thought I'm going to see a very big collision with that thing and the ground, but that didn't happen. 333 00:23:50,000 --> 00:23:58,000 It came to the ground and stopped right there. It was so bright that I could see the sands of the girls. 334 00:23:59,000 --> 00:24:07,000 Then the projectile strangely vanishes, and the larger object with flashing lights is also nowhere to be seen. 335 00:24:07,000 --> 00:24:14,000 There was no splash of the sands. There was no burning. Nothing. 336 00:24:21,000 --> 00:24:27,000 Iranian pilot Parviz Jafari is scouring the desert south of Tehran for a possible downed UFO. 337 00:24:29,000 --> 00:24:34,000 Jafari can't see anything, but he does hear something in his radio coming from the crash site. 338 00:24:37,000 --> 00:24:45,000 They call it emergency squawk when there's a box or there's some device when something hits the ground that sends out a signal so that people can locate it. 339 00:24:46,000 --> 00:24:49,000 And for some reason, where this thing went down, there was emergency squawk going out. 340 00:24:50,000 --> 00:24:52,000 Another airplane reported hearing the same sound. 341 00:24:53,000 --> 00:24:59,000 With a clear signal locating the object in the darkness, Jafari is allowed to land at last. 342 00:25:00,000 --> 00:25:05,000 At first blight, he joins the search and rescue teams hunting for the object. 343 00:25:07,000 --> 00:25:14,000 That sound was still beeping, so we went there and we find nothing. Nothing, nothing. 344 00:25:16,000 --> 00:25:19,000 That day, Jafari is debriefed by superior officers. 345 00:25:20,000 --> 00:25:28,000 They called us to the Air Force Headquarter. I had an interview there. I told them the whole story. 346 00:25:28,000 --> 00:25:37,000 And I saw an American colonel was standing at the corner of the room and he was taking notes. 347 00:25:39,000 --> 00:25:47,000 As well as supplying Iran with state-of-the-art U.S. technology, American military advisors are a fixture at many Iranian bases. 348 00:25:48,000 --> 00:25:56,000 During this time of Cold War tension, Jafari's encounter catches the eye of one advisor, Lieutenant Colonel Olan Mui. 349 00:25:56,000 --> 00:26:04,000 After hearing Jafari's debrief, he files a report that is circulated to a wide array of senior policymakers in Washington, D.C. 350 00:26:05,000 --> 00:26:15,000 This particular memo was sent around to many departments within the U.S. government, the White House, the CIA, the State Department, a whole list of very important agencies. 351 00:26:16,000 --> 00:26:22,000 In the document, Lieutenant Colonel Mui gives a thorough description of the incident, but reaches no firm conclusion. 352 00:26:22,000 --> 00:26:32,000 The analysis of the case referred to it as a UFO, so they were never able to explain what it was. It just went on the record as something unidentified. 353 00:26:35,000 --> 00:26:42,000 So there seems to be little doubt that a lot of people saw something and that it was taken seriously in both Iran and in Washington. 354 00:26:44,000 --> 00:26:46,000 But just what could it have been? 355 00:26:47,000 --> 00:26:56,000 One possibility is that the source of the sightings is some kind of aircraft. Could this object be either American or Russian secret technology? 356 00:26:57,000 --> 00:27:00,000 Aviation historian Peter Merlin considers the question. 357 00:27:01,000 --> 00:27:10,000 Considering the state of U.S.-Iranian relations at the time, I hardly think it likely that the U.S. would have been conducting any sort of military operations in Iranian airspace. 358 00:27:11,000 --> 00:27:19,000 More likely, it would be a belligerent neighbor such as Iraq, who would have been supplied by the Soviets, possibly with electronic warfare devices. 359 00:27:20,000 --> 00:27:25,000 An electronic warfare device could explain the equipment malfunctions experienced by the F-4s. 360 00:27:26,000 --> 00:27:33,000 There are all manner of different kinds of avionics that can be used to jam communications, radar tracking. 361 00:27:34,000 --> 00:27:39,000 But Parviz Jafari, an experienced combat aviator, discounts this idea. 362 00:27:40,000 --> 00:27:52,000 The jamming is reflected only on the radar, but you can't jam the missile system or you can't jam the instrument system. 363 00:27:53,000 --> 00:28:02,000 If there was no deliberate attempt to disable the fighter's systems, then perhaps the malfunctions are the result of a more straightforward explanation. 364 00:28:03,000 --> 00:28:07,000 Another experienced pilot, David Higgins, thinks this is a possibility. 365 00:28:08,000 --> 00:28:24,000 Aircraft instruments and radios are electrically powered, and sometimes if you have a failure of a bus bar or a generator, you may lose certain instrumentation and some of the radio navigation equipment. 366 00:28:26,000 --> 00:28:33,000 Electrical failures do happen, and there is a possibility that both planes suffer the same fault. 367 00:28:33,000 --> 00:28:40,000 Yet no aircraft malfunction can explain the most striking thing about the incident. 368 00:28:41,000 --> 00:28:45,000 The bright light seen by Jafari and several other witnesses. 369 00:28:47,000 --> 00:28:51,000 Astronomer Professor Nigel Hembest thinks he knows what the lights could be. 370 00:28:52,000 --> 00:28:55,000 A well-documented piece of space junk. 371 00:28:56,000 --> 00:29:01,000 Among the bigger bits of space junk that can fall down to earth are parts of rockets which are launching satellites into space. 372 00:29:02,000 --> 00:29:08,000 And interestingly enough, on the same night there was a light seen over Morocco where there were UFO reports. 373 00:29:09,000 --> 00:29:13,000 And it turns out that that was actually a rocket engine from a Russian rocket which had launched into orbit. 374 00:29:14,000 --> 00:29:20,000 We don't know of any burning up rocket that happened over Iran on that night, but we can't rule out the possibility. 375 00:29:21,000 --> 00:29:25,000 Often when objects burn up in the atmosphere, they glow in a variety of colors. 376 00:29:26,000 --> 00:29:33,000 As they come down through the earth's atmosphere and burn up, if they've got particular elements, for example copper will make it glow green. 377 00:29:34,000 --> 00:29:37,000 Or if they light up the earth's gases in a particular way. 378 00:29:38,000 --> 00:29:43,000 If there's oxygen, then it will glow green as it goes through the oxygen region, or red as it goes through the nitrogen region. 379 00:29:44,000 --> 00:29:49,000 David Higgins believes there is a reason the aircraft malfunction occurs at the same time the lights appear. 380 00:29:50,000 --> 00:29:55,000 It could of course be a coincidence. It could be that there is a fault with the aircraft. 381 00:29:56,000 --> 00:30:02,000 And that's why he's seen these faults at the same time as seeing this object and he has linked the two together. 382 00:30:05,000 --> 00:30:08,000 But it still leaves one more unexplained element to the story. 383 00:30:09,000 --> 00:30:14,000 The strange radio signal. The squawk heard by Jaffari and the search and rescue team. 384 00:30:15,000 --> 00:30:24,000 There are reports in this case that a transponder was found on the ground and reports that it had been dislodged from the aircraft or came away in turbulence. 385 00:30:25,000 --> 00:30:32,000 If you did find a transponder on the ground, you would expect to see that as part of wreckage of an aircraft. 386 00:30:33,000 --> 00:30:35,000 You would not find a transponder by itself. 387 00:30:36,000 --> 00:30:41,000 There is no one single explanation for what happened in the skies over Iran that night. 388 00:30:42,000 --> 00:30:45,000 It's quite possibly just a bizarre coincidence. 389 00:30:46,000 --> 00:30:50,000 But the mystery continues to captivate believers and skeptics alike. 390 00:30:51,000 --> 00:30:54,000 It's so well documented. There were so many witnesses. 391 00:30:55,000 --> 00:31:01,000 So because it's so well documented and so fascinating, it's really one of the most interesting cases that we have on record as far as I'm concerned. 392 00:31:01,000 --> 00:31:11,000 March 9th, 1995. Taronga, New Zealand. 393 00:31:12,000 --> 00:31:20,000 Local port employee Bill McKinnon is out for an afternoon's pleasure fishing on New Zealand's tranquil Bay of Plenty. 394 00:31:21,000 --> 00:31:27,000 It was bright sunlight like it is today. A very clear day. 395 00:31:28,000 --> 00:31:35,000 The day passes without incident until about 1.15pm when Bill sees something out of the corner of his eye. 396 00:31:36,000 --> 00:31:43,000 I turned around and noticed there was a strange object in the sky coming across from northeast to southwest. 397 00:31:44,000 --> 00:31:50,000 It looked like a sphere, a very shiny sphere, white and silver. 398 00:31:50,000 --> 00:31:53,000 But it had a shimmer in front of it. 399 00:31:54,000 --> 00:31:58,000 And it's like the pushing of a ship's bow in the water. 400 00:31:59,000 --> 00:32:04,000 And it was rippling like this in front, very, very noticeably. 401 00:32:05,000 --> 00:32:09,000 The object appears to be moving at incredible speed and has a ghostly white tail. 402 00:32:10,000 --> 00:32:12,000 And yet there is no noise. 403 00:32:13,000 --> 00:32:17,000 I know how fast an airplane goes and it was a lot quicker than an airplane. 404 00:32:21,000 --> 00:32:24,000 I can't clarify what I saw that day. 405 00:32:25,000 --> 00:32:30,000 But it definitely was an unidentified flying object of a fairly large proportion. 406 00:32:34,000 --> 00:32:38,000 It's possible that this is a simple case of mistaken identity. 407 00:32:39,000 --> 00:32:43,000 The object Bill saw was a plane or perhaps some natural phenomenon. 408 00:32:45,000 --> 00:32:48,000 Except Bill is an experienced observer of the skies. 409 00:32:49,000 --> 00:32:54,000 One of his jobs at the port is to feed data to the Meteorological Service of New Zealand, 410 00:32:55,000 --> 00:32:58,000 a role that requires a detailed knowledge of the atmospheric phenomena. 411 00:33:00,000 --> 00:33:06,000 To do this we were educated as to how to divide the sky, whether it be cloudy or partly cloudy. 412 00:33:07,000 --> 00:33:13,000 There was quite a lot in giving a description and I learnt how to observe. 413 00:33:14,000 --> 00:33:20,000 Perplexed by a sighting, Bill gets in touch with a local UFO investigation group run by Suzanne Hansen. 414 00:33:21,000 --> 00:33:25,000 Suzanne is a believer in the existence of extraterrestrials on Earth 415 00:33:26,000 --> 00:33:30,000 and her group specialises in sightings by pilots and other aviation experts. 416 00:33:31,000 --> 00:33:34,000 Well New Zealand has quite a rich history of aviation sightings. 417 00:33:35,000 --> 00:33:40,000 There have been some fairly phenomenal, world-renowned sightings concerning pilots and air traffic controllers. 418 00:33:40,000 --> 00:33:47,000 And I decided that that was an area that needed to be focused on because it carries a great deal of credibility in the public eye. 419 00:33:48,000 --> 00:33:52,000 She gives Bill a shocking revelation. He is not alone. 420 00:33:53,000 --> 00:34:00,000 60 miles inland, in the town of Hamilton, another highly reliable eyewitness has seen something that day. 421 00:34:01,000 --> 00:34:03,000 Air Traffic Controller Graham Opie. 422 00:34:04,000 --> 00:34:09,000 In 1995 I was the control tower manager at Hamilton Airport. 423 00:34:10,000 --> 00:34:13,000 I was responsible for the daily operation of the control tower. 424 00:34:14,000 --> 00:34:18,000 I was a practicing air traffic controller and also a commercial pilot at that time. 425 00:34:19,000 --> 00:34:25,000 On March 9th 1995, Graham was on duty in the tower, supervising a team of air traffic controllers. 426 00:34:26,000 --> 00:34:33,000 I happened to be looking south of the control tower and I observed a brilliant flash of light shining at me. 427 00:34:34,000 --> 00:34:39,000 It was exactly like somebody was reflecting the sun off a mirror at you. It was extremely bright. 428 00:34:40,000 --> 00:34:44,000 It had a tiny tail to it. Orange and red in colour and it was extremely fast. 429 00:34:45,000 --> 00:34:48,000 Graham immediately turns to his colleagues in the tower. 430 00:34:49,000 --> 00:34:53,000 The first thing I said when I saw the object flash across the sky was, hey did you guys see that? 431 00:34:54,000 --> 00:34:59,000 And both of them said no, unfortunately. So I had no back-up witnesses but I knew what I'd seen. 432 00:35:00,000 --> 00:35:06,000 Graham's fellow controllers may not have seen the bright streak with their eyes, but maybe it's been spotted on radar. 433 00:35:07,000 --> 00:35:11,000 We have a direct line to the air traffic control centre in Auckland where they've got radar up there. 434 00:35:12,000 --> 00:35:15,000 The radar controller in Auckland said they had no targets to the south of Hamilton. 435 00:35:16,000 --> 00:35:19,000 No eye witnesses and no radar contact. 436 00:35:20,000 --> 00:35:24,000 At this stage, Graham thinks he's the only one to have seen the strange object. 437 00:35:29,000 --> 00:35:32,000 Then he gets a phone call from Suzanne Hansen. 438 00:35:32,000 --> 00:35:38,000 She explains his signing is not a one-off, but part of a whole series of similar events. 439 00:35:39,000 --> 00:35:45,000 We know that it was reported in the newspaper and it was probably seen by hundreds if not thousands of people. 440 00:35:46,000 --> 00:35:51,000 They didn't know what it was. Some people thought it was a jet plane. People thought it was anything from a meteor to a comet. 441 00:35:52,000 --> 00:35:56,000 It was completely silent and would have covered quite a distance over the central North Island. 442 00:35:57,000 --> 00:36:04,000 Once Suzanne had contacted me and we had that other information available, she requested that I do a proper investigation of the sighting. 443 00:36:05,000 --> 00:36:08,000 Over the coming weeks, he would uncover remarkable evidence. 444 00:36:09,000 --> 00:36:12,000 I was positive that it wasn't of an earthly origin. 445 00:36:18,000 --> 00:36:24,000 Graham Obey begins a detailed investigation into a suspected UFO he's seen on New Zealand's North Island. 446 00:36:26,000 --> 00:36:29,000 He begins with the most obvious possibilities. 447 00:36:30,000 --> 00:36:37,000 My initial reaction when I saw the object was it was some kind of jet fighter because of the speed it was travelling at. 448 00:36:38,000 --> 00:36:46,000 That theory would also explain one of Bill McKinnon's observations, that he witnessed a rippling effect like a bow wave around the front of the UFO. 449 00:36:48,000 --> 00:36:54,000 When aircraft approach supersonic speeds, they can create what's known as a sonic boom cloud. 450 00:36:55,000 --> 00:37:00,000 It's caused by water vapor condensing around the craft between waves of high pressure air. 451 00:37:02,000 --> 00:37:08,000 But if what he saw was a jet, that raises the question, why didn't it register on ground radar? 452 00:37:09,000 --> 00:37:18,000 The fact that it didn't meant that it was either cloaking itself or it was travelling so fast that the radar dish just didn't have time to register the object. 453 00:37:19,000 --> 00:37:26,000 But the fact that it didn't appear on radar meant that it wasn't anything of our air force, it was just a UFO. 454 00:37:27,000 --> 00:37:33,000 A UFO doesn't mean to say that it's got little green mean flying around it or anything, but whether it was extra terrestrial or not, I had no idea at that stage. 455 00:37:34,000 --> 00:37:40,000 As part of his investigation, OP interviews Bill McKinnon and a crucial piece of evidence emerges. 456 00:37:40,000 --> 00:37:47,000 The sightings of the two men were just three minutes apart, but separated by a distance of more than 60 miles. 457 00:37:48,000 --> 00:37:51,000 And that's not the most surprising thing. 458 00:37:52,000 --> 00:38:02,000 From the sighting in Terraria to the sighting in Hamilton, it actually climbed and it increased in speed, which showed that it was operating in some kind of controlled manner. 459 00:38:03,000 --> 00:38:15,000 The results of Graham's investigation led him, Suzanne and Bill to the same conclusion. The object was possibly of extra terrestrial origin. 460 00:38:16,000 --> 00:38:30,000 I was positive that it wasn't a man-made aircraft. It was travelling too fast. The speed of the object was the deciding factor to say to me that it wasn't of an earthly origin. 461 00:38:31,000 --> 00:38:44,000 I really have to have an open mind about it and I'm willing to believe that it was a spaceship of some sort, extra terrestrial. I don't believe it's from this country or from the will. 462 00:38:46,000 --> 00:38:59,000 Seasoned observers of the sky, like astronomers Nigel Hanbest and Carolyn Crawford, agree with Bill. The object is almost certainly not from New Zealand and maybe not even from this world. 463 00:39:00,000 --> 00:39:04,000 The accounts that I've seen match very closely to a fireball crossing the sky. 464 00:39:05,000 --> 00:39:19,000 A fireball is a meteor that is intensely bright, so you've got something more massive burning up in our atmosphere. And you get light not just from the meteor itself heating up, but also from the way it energises the air as it travels through. 465 00:39:20,000 --> 00:39:25,000 So there's a lot of light generated. It can be as bright as the sun, even in extreme cases. 466 00:39:25,000 --> 00:39:31,000 Fireballs are rare occurrences, but several had been documented on camera in recent years. 467 00:39:32,000 --> 00:39:39,000 One of the most famous cases is a fireball that passed over the city of Chelyabinsk, Russia in 2013. 468 00:39:40,000 --> 00:39:52,000 And you can see from the videos that were taken at the time from car dashboards, you can see the thing crossing the sky, the blue daytime sky. And that was so brilliant. It was easy to see, in fact, it cast shadows even in daytime. 469 00:39:55,000 --> 00:39:58,000 Those close to the case discount this theory. 470 00:39:59,000 --> 00:40:11,000 We consulted the late Dr Frank Bateson, who's New Zealand's most renowned astronomer, who was quite sure given the full description that he looked at, it couldn't possibly have been a meteor. 471 00:40:12,000 --> 00:40:19,000 It gained in height, it moved on a curved path and it seemed to have a very bright reflective object at the front of it. 472 00:40:20,000 --> 00:40:23,000 And there's one other major flaw in the fireball argument. 473 00:40:24,000 --> 00:40:29,000 It was completely silent. There was no sonic boom and no sound attached to the sighting. 474 00:40:30,000 --> 00:40:36,000 The Chelyabinsk fireball creates a sonic boom so powerful, it shatters thousands of windows across the city. 475 00:40:38,000 --> 00:40:42,000 However, some fireballs are in fact completely silent. 476 00:40:43,000 --> 00:40:51,000 When I read this report of it going across the sky in this way and was visible for quite a long period of time, but wasn't seen to come down to the ground. 477 00:40:51,000 --> 00:40:58,000 It reminds me of a case in 1972 called the Great Daylight Fireball, which was seen from North America. 478 00:40:59,000 --> 00:41:04,000 This was actually a space rock which skimmed the Earth's atmosphere. It came in the top of the atmosphere. 479 00:41:05,000 --> 00:41:09,000 It came across, skimmed like a stone, skipping across water and went back out into space again. 480 00:41:13,000 --> 00:41:18,000 This could explain the eyewitness accounts of seeing an object moving horizontally rather than falling. 481 00:41:19,000 --> 00:41:27,000 And the altitude of the object, high in the upper atmosphere, would allow it to be seen almost simultaneously from both Hamilton and Tauranga. 482 00:41:28,000 --> 00:41:31,000 It would also explain why the object made no sound. 483 00:41:32,000 --> 00:41:35,000 The ones that burn up at the top of the atmosphere, we generally don't hear a sonic boom. 484 00:41:37,000 --> 00:41:47,000 But how could both Graham Opie, a veteran air traffic controller, and Bill McKinnon, a seasoned meteorologist, be so mistaken about the object's speed and altitude? 485 00:41:49,000 --> 00:41:52,000 These men spend their professional lives watching the sky. 486 00:41:54,000 --> 00:41:58,000 But as human perception expert Bo Lotto explains, it's not that simple. 487 00:42:00,000 --> 00:42:07,000 Because of their history of experience, especially if they're an air traffic controller, and let's imagine that it's an airplane that they're looking at, not surprisingly, 488 00:42:08,000 --> 00:42:12,000 they have a very good sense of how far it will be because of their history of experience. 489 00:42:12,000 --> 00:42:24,000 If, however, they're looking at something that's unfamiliar, there's no basis then to judge its distance because this thing could be a huge object very far away or a small object up close. 490 00:42:25,000 --> 00:42:28,000 And you have no way of knowing unless, to a certain extent, you know what that object is. 491 00:42:30,000 --> 00:42:32,000 Nobody can be entirely sure of what was seen that day. 492 00:42:33,000 --> 00:42:37,000 As with so many UFO sightings, there are many theories, but few hard facts. 493 00:42:38,000 --> 00:42:42,000 We may never know the true cause of the case, so the mystery remains. 494 00:42:43,000 --> 00:42:49,000 If we look at what the object could have been, we can go through a logical process of elimination. 495 00:42:50,000 --> 00:42:56,000 If it wasn't a meteor or a natural object, and it certainly wasn't an aircraft, then it has to be something else. 496 00:42:57,000 --> 00:42:59,000 And that something else could well be something from beyond our planet.
