1 00:00:00,000 --> 00:00:11,993 This series presents information based in part on theory and conjecture. 2 00:00:11,993 --> 00:00:16,514 The producer's purpose is to suggest some possible explanations, but not necessarily 3 00:00:16,514 --> 00:00:19,995 the only ones to the mysteries we will examine. 4 00:00:19,995 --> 00:00:46,001 There is a body of water from which the cry of distress comes more often for a square mile 5 00:00:46,001 --> 00:00:55,003 than any other body of water in the world. 6 00:00:55,003 --> 00:01:06,006 It is not the Devil's Sea off Japan, the tumultuous waters of the Cape Horn, nor the deadly calm of the Sargasso Sea. 7 00:01:06,006 --> 00:01:11,007 It is an area where the search and rescue capabilities have no equal. 8 00:01:11,007 --> 00:01:18,008 Not the Bermuda Triangle, but another triangle, a triangle formed by the Great Lakes, 9 00:01:18,008 --> 00:01:30,011 locked in the heart of industrial North America. 10 00:01:30,011 --> 00:01:40,014 The man who has accumulated and assessed the data that has led him to designate the Great Lakes as perhaps the greatest disaster area in the world is J. Leland Gurley. 11 00:01:40,014 --> 00:01:52,017 J. Gurley is not only an experienced author and journalist, he is also a highly qualified professional flying instructor. 12 00:01:52,017 --> 00:02:00,018 I've flown thousands of miles through the Bermuda Triangle, and I've been out of radio contact with anyone there for as much as an hour at a time. 13 00:02:00,018 --> 00:02:11,021 It's much easier to understand how someone could disappear in a vast expanse of ocean like that than here, where you can see Canada off our right wing tip and the United States off our left wing tip. 14 00:02:11,021 --> 00:02:18,023 I can overfly this lake in less than 10 minutes. No one is ever out of radio contact here. 15 00:02:18,023 --> 00:02:24,024 We can communicate with at least 100 different government employees in the United States and Canada right now. 16 00:02:24,024 --> 00:02:28,025 It's inconceivable that anyone could disappear here. 17 00:02:28,025 --> 00:02:33,026 And yet, disappear they do, and under circumstances of mystery. 18 00:02:33,026 --> 00:02:43,029 50 mile an hour headwinds that no one else feels, dangers that come so suddenly, the victim never even cries for help. 19 00:02:43,029 --> 00:02:51,031 In terms of the sheer magnitude of tragedy, Gurley has discovered that the Great Lakes surpassed the so-called Bermuda Triangle, 20 00:02:51,031 --> 00:03:00,033 and the Bermuda Triangle covers some one and a half million square miles, 16 times the size of the five Great Lakes combined. 21 00:03:00,033 --> 00:03:12,036 These are not strange remote waters or vast stretches of ocean. These are completely enclosed freshwater pools, the playground of middle America. 22 00:03:12,036 --> 00:03:23,038 On the shores of the Great Lakes stand the great American cities of Chicago, Detroit, Buffalo and Cleveland. 23 00:03:23,038 --> 00:03:31,040 Piercing the sky over Toronto, on the shores of Lake Ontario, the highest man-made structure in the world. 24 00:03:31,040 --> 00:03:38,042 The CN Tower stands as the ultimate pinnacle of highly sophisticated communications technology. 25 00:03:39,042 --> 00:03:46,044 Traffic controllers urge pilots flying the lakes to report continuously to ground stations. 26 00:03:46,044 --> 00:03:51,045 A 10 second lapse will launch full scale search and rescue. 27 00:03:51,045 --> 00:03:57,046 And yet, the fact remains that there is high incidence of inexplicable disaster. 28 00:03:57,046 --> 00:04:06,048 Jay Gurley assiduously follows up any clue, any lead which may shed light on the mysterious tragedies. 29 00:04:06,048 --> 00:04:10,049 He has pursued high government officials in Washington and Ottawa. 30 00:04:10,049 --> 00:04:18,051 Interviewed the men on the spot, the highly skilled search teams operated by the police and the Coast Guards of two nations. 31 00:04:21,052 --> 00:04:28,054 He has spent days at the marinas to discuss the weather peculiarities with yachtsmen whose lives depend on their knowledge. 32 00:04:28,054 --> 00:04:32,054 What's the worst thing that can happen in a situation like this? 33 00:04:33,055 --> 00:04:44,057 He has fed his voluminous documentation gathered over two years into the highly sophisticated computer banks at such electronics nerve centers as the University of Toronto. 34 00:04:44,057 --> 00:04:50,059 Searching for patterns, searching for correlations, searching for explanations. 35 00:04:50,059 --> 00:04:52,059 Stop it right there if you would. 36 00:04:52,059 --> 00:04:56,060 That's the accident I was telling you about just off Milwaukee. 37 00:04:56,060 --> 00:04:58,061 That aircraft was at in-read altitude. 38 00:04:58,061 --> 00:05:00,061 It was talking to air traffic control. 39 00:05:00,061 --> 00:05:03,062 It was a clear day, very calm. 40 00:05:03,062 --> 00:05:07,063 The aircraft disappeared from radar from an altitude of about 5,000 feet. 41 00:05:07,063 --> 00:05:12,064 No trace of that airplane or anyone aboard it has ever been found in this day. 42 00:05:15,065 --> 00:05:19,066 And finally, not dried data, but flesh and blood. 43 00:05:19,066 --> 00:05:23,067 Eye witnesses who survived to describe their bewilderment. 44 00:05:23,067 --> 00:05:30,068 Such a man is Robert Joy, Jr. of Michigan, a policeman, a pilot and a professor of criminology. 45 00:05:30,068 --> 00:05:36,070 On April 23, 1973, Bob watched his father vanish. 46 00:05:36,070 --> 00:05:40,071 His father was flying a safe, well-equipped amphibious aircraft. 47 00:05:40,071 --> 00:05:43,071 Is there any difference between this airplane and the airplane your father disappeared in? 48 00:05:43,071 --> 00:05:45,072 No, it's exactly the same type here. 49 00:05:45,072 --> 00:05:48,073 Bob Joy was in another plane a few hundred feet away. 50 00:05:48,073 --> 00:05:50,073 They were over shallow Lake Erie. 51 00:05:50,073 --> 00:05:54,074 The water was not rough. There was no cry for help. 52 00:05:54,074 --> 00:05:58,075 I got a radio message from my dad and I couldn't understand what he said. 53 00:05:58,075 --> 00:06:03,076 The frequency that we were on was a 122.8 to Unicom frequency. 54 00:06:03,076 --> 00:06:07,077 It was very congested, so I looked back out the right side of the airplane 55 00:06:07,077 --> 00:06:09,077 and I didn't see the Lake Amphibian at all. 56 00:06:09,077 --> 00:06:12,078 It had been there right along through the whole trip. 57 00:06:12,078 --> 00:06:16,079 No trace of the Lake Amphibian was ever found. 58 00:06:21,080 --> 00:06:26,082 The disappearances of small aircraft are hard enough to explain. 59 00:06:26,082 --> 00:06:32,083 The strange disasters of the Great Laker Boats are perhaps even more mystifying. 60 00:06:32,083 --> 00:06:37,084 These are ships that are built for lakes, never far from shore, 61 00:06:37,084 --> 00:06:42,085 massively equipped with every conceivable safety and communications device. 62 00:06:42,085 --> 00:06:45,086 When the Edmund Fitzgerald was launched, 63 00:06:45,086 --> 00:06:49,087 it was the largest of the Great Laker Boats. 64 00:06:49,087 --> 00:06:54,088 When she sailed from Duluth, Minnesota on November 9, 1975, 65 00:06:54,088 --> 00:07:00,090 she too was sailing safely in tandem with another Laker, the Arthur M. Anderson. 66 00:07:00,090 --> 00:07:03,090 They easily weathered a mild storm, 67 00:07:03,090 --> 00:07:07,091 but to be safe, the Fitzgerald checked her speed to close the distance 68 00:07:07,091 --> 00:07:10,092 between her and the Anderson. 69 00:07:10,092 --> 00:07:13,093 A snow flurry obscured their view briefly, 70 00:07:13,093 --> 00:07:19,094 but the radar told the Anderson that the Fitzgerald was less than nine miles ahead. 71 00:07:19,094 --> 00:07:23,095 When the flurry lifted, the Anderson could see for 20 miles, 72 00:07:23,095 --> 00:07:27,096 but there was no Fitzgerald. 73 00:07:27,096 --> 00:07:32,097 She'd gone with a sudden convulsion to the bottom with all hands. 74 00:07:34,098 --> 00:07:36,098 When the wreckage was found, 75 00:07:36,098 --> 00:07:41,099 it was discovered that every lifeboat was still securely fastened. 76 00:07:41,099 --> 00:07:46,100 The peculiar thing about that accident is that for three hours at least, 77 00:07:46,100 --> 00:07:49,101 the Edmund Fitzgerald was slowly filling up with water. 78 00:07:49,101 --> 00:07:53,102 We know that now, even though no one on board the Fitzgerald knew it at the time. 79 00:07:53,102 --> 00:07:57,103 What's really strange about this accident is that no one did know that. 80 00:07:57,103 --> 00:07:59,104 No one put on life jackets. 81 00:07:59,104 --> 00:08:01,104 No one called for distress. 82 00:08:01,104 --> 00:08:05,105 In fact, up until about one minute before the accident, 83 00:08:05,105 --> 00:08:08,106 before the Fitzgerald finally went under the water, 84 00:08:08,106 --> 00:08:12,107 the first mate of the Fitzgerald was saying that the ship was all right. 85 00:08:12,107 --> 00:08:14,107 They were having no problem. 86 00:08:14,107 --> 00:08:20,109 At one of the cam loops and the strange events of December 7th, 1927, 87 00:08:20,109 --> 00:08:24,110 the cam loops too had plotted a cautious course, 88 00:08:24,110 --> 00:08:28,110 entering Lake Superior in tandem with the freighter Quaidoc. 89 00:08:28,110 --> 00:08:32,111 In the late afternoon, the man on the Quaidoc sighted rocks ahead 90 00:08:32,111 --> 00:08:36,112 and swirred successfully to Starboard to avoid them. 91 00:08:36,112 --> 00:08:42,114 The cam loops was following and could clearly see the Quaidoc's action. 92 00:08:42,114 --> 00:08:49,115 But the cam loops sailed on, despite frantic warning blasts from the Quaidoc's great steam whistle. 93 00:08:49,115 --> 00:08:51,116 She was not seen again. 94 00:08:51,116 --> 00:08:54,117 It was presumed she was dashed on the rocks of Isle Royale, 95 00:08:54,117 --> 00:08:59,118 but there was no wreckage, no bodies, no evidence whatsoever 96 00:08:59,118 --> 00:09:02,119 that the cam loops had ever existed. 97 00:09:04,119 --> 00:09:08,120 Jay Gourlet's search into the strange history of the lakes 98 00:09:08,120 --> 00:09:13,121 led him back into the exhaustive records and preserved evidence of great lake shipping 99 00:09:13,121 --> 00:09:16,122 kept at the Marine Museum on Toronto's waterfront. 100 00:09:18,122 --> 00:09:22,123 The contemporary events first aroused my interest in this region. 101 00:09:22,123 --> 00:09:27,124 Research quickly led me into these records of the 18th and 19th century. 102 00:09:27,124 --> 00:09:33,126 We know, for example, that the first commercial vessel to sail on the Great Lakes, 103 00:09:33,126 --> 00:09:38,127 the Griffin and all aboard her, vanished on her maiden voyage. 104 00:09:38,127 --> 00:09:43,128 From relics like these, we know precisely what has caused most shipping accidents. 105 00:09:43,128 --> 00:09:46,129 But this is not always true in the Great Lakes. 106 00:09:46,129 --> 00:09:48,129 Often, evidence is contradictory. 107 00:09:48,129 --> 00:09:51,130 Other times, evidence is totally non-existent. 108 00:09:51,130 --> 00:09:56,131 There is, for example, an exquisite ship's figurehead found adrift, 109 00:09:56,131 --> 00:10:00,132 but there is no record of any ship ever carrying this figurehead. 110 00:10:02,133 --> 00:10:08,134 During the winter of 1902, divers searched unsuccessfully for the wreckage of the Bannock Burn. 111 00:10:08,134 --> 00:10:13,135 They were not surprised because they could not believe that she had sunk. 112 00:10:13,135 --> 00:10:16,136 She was last spotted by a passing ship. 113 00:10:16,136 --> 00:10:19,137 She was pointed out by the skipper to his mate. 114 00:10:19,137 --> 00:10:25,138 But when the mate turned his head to look at the proud vessel, the Bannock Burn was gone. 115 00:10:27,139 --> 00:10:35,141 From time to time, over the years, she has been reported sailing on over the lakes. 116 00:10:38,141 --> 00:10:42,142 And then there were the wrecks that were only too painfully evident. 117 00:10:42,142 --> 00:10:47,143 But the phenomenon that destroyed them vanished as suddenly as it came. 118 00:10:47,143 --> 00:10:54,145 The Layfield, the James E. Davidson, the Hebu, the Sakham. 119 00:10:54,145 --> 00:11:00,146 All proceeding through relatively calm waters when a single gigantic wave struck them down. 120 00:11:00,146 --> 00:11:05,148 A mountain of boiling water rising for one too moutchewous moment. 121 00:11:05,148 --> 00:11:10,149 Meteorologists call them a seash wave, but cannot explain them. 122 00:11:10,149 --> 00:11:14,150 They were first recorded in the Great Lakes in 1872. 123 00:11:14,150 --> 00:11:17,151 They are not caused by wind. 124 00:11:18,151 --> 00:11:24,152 The bizarre events of the lakes go back beyond the first records of the white man. 125 00:11:24,152 --> 00:11:30,154 The so-called seash wave is part of the legend of the Chippewa Indians of Lake Superior. 126 00:11:30,154 --> 00:11:40,156 They still speak of Nanabazhu Sturgeon, a monster fish that with a flick of his tail was said to destroy the mightiest vessel. 127 00:11:40,156 --> 00:11:45,157 Indian legend is connected to another extraordinary case history. 128 00:11:45,157 --> 00:11:51,159 The ship was called the Wabuno, an Algonquin name for black magician. 129 00:11:51,159 --> 00:11:58,160 On November 20th, 1879, a doctor's wife claims she had a vision of the ship's destruction. 130 00:11:58,160 --> 00:12:01,161 It was assumed she was hysterical. 131 00:12:01,161 --> 00:12:06,162 The wreckage was found in Lake Huron, battered by some tremendous force. 132 00:12:06,162 --> 00:12:10,163 But not a single body was ever recovered. 133 00:12:11,163 --> 00:12:16,165 But the growing legend of the lakes is not only based on misty tales of superstition. 134 00:12:16,165 --> 00:12:23,166 It is also based on cases that are all the more chilling because they are fully documented. 135 00:12:24,166 --> 00:12:35,169 United Airlines Flight 389, a Boeing 727 similar to this one, a flight from New York to Chicago, August 16th, 1965. 136 00:12:35,169 --> 00:12:37,169 The facts are solid. 137 00:12:37,169 --> 00:12:41,170 The captain's voice was recorded by a traffic controller. 138 00:12:41,170 --> 00:12:45,171 The flight path was tracked on highly sophisticated NORAD equipment. 139 00:12:45,171 --> 00:12:48,172 There was no mechanical malfunction. 140 00:12:48,172 --> 00:12:51,173 Three highly qualified pilots were on the flight deck. 141 00:12:51,173 --> 00:12:54,174 They could see Chicago in the distance. 142 00:12:58,174 --> 00:13:02,175 The aircraft descended perfectly normally to 6,000 feet. 143 00:13:02,175 --> 00:13:06,176 It was then instructed to level out according to regular procedure. 144 00:13:06,176 --> 00:13:09,177 But the aircraft did not level out. 145 00:13:09,177 --> 00:13:15,179 It continued to descend for three minutes until it flew right into Lake Michigan. 146 00:13:15,179 --> 00:13:19,179 There was no attempt to arrest the descent. 147 00:13:19,179 --> 00:13:21,180 It was a clear day just like this. 148 00:13:21,180 --> 00:13:26,181 In fact, up until one second before the United Airlines Flight 389 hit the water, 149 00:13:26,181 --> 00:13:32,183 killing all 30 aboard, the pilot was talking to air traffic control about his altimeter setting. 150 00:13:32,183 --> 00:13:38,184 He was looking at his altimeter, he was setting it, he was paying attention to his altimeter. 151 00:13:38,184 --> 00:13:40,184 The copilot was flying the airplane. 152 00:13:40,184 --> 00:13:42,185 He could see the water below him. 153 00:13:42,185 --> 00:13:46,186 He could see the city of Chicago in the distance there about 15 miles away. 154 00:13:46,186 --> 00:13:50,187 In light of these facts, the National Transportation Safety Board concluded 155 00:13:50,187 --> 00:13:56,188 that no possible explanation can be offered for the action of this crew. 156 00:13:56,188 --> 00:13:58,189 No possible explanation. 157 00:13:58,189 --> 00:14:02,190 And yet there is another case involving exactly the same elements. 158 00:14:02,190 --> 00:14:06,191 An altimeter charting a path to certain death. 159 00:14:06,191 --> 00:14:12,192 Right here is where Detroit departure control cleared the Saber liner that was owned by General Motors 160 00:14:12,192 --> 00:14:15,193 to begin its approach into Pontiac. 161 00:14:15,193 --> 00:14:20,194 Up about five miles is where the Saber liner began its descent. 162 00:14:20,194 --> 00:14:25,195 And beyond that, another two miles is where the Saber liner finally crashed into the ground. 163 00:14:25,195 --> 00:14:28,196 At no time was there anything wrong with the aircraft itself. 164 00:14:28,196 --> 00:14:31,197 It was under full control of the pilot throughout the flight. 165 00:14:31,197 --> 00:14:34,197 Here there is miraculously a survivor. 166 00:14:34,197 --> 00:14:40,199 He was the copilot that night, a man with vast experience and a spotless record. 167 00:14:40,199 --> 00:14:42,199 Howard Herbst. 168 00:14:42,199 --> 00:14:44,200 The crew is something like this. 169 00:14:44,200 --> 00:14:47,200 They said, you're cleared to 2,700 feet. 170 00:14:47,200 --> 00:14:53,202 Clear for the approach, contact Pontiac Tower at the outer marker. 171 00:14:53,202 --> 00:14:59,203 And 2,700 feet is the altitude for the procedure turn. 172 00:14:59,203 --> 00:15:03,204 So we descended to the 2,700 feet. 173 00:15:03,204 --> 00:15:05,205 That I know we were at. 174 00:15:05,205 --> 00:15:09,206 I checked that altitude and both of us did. 175 00:15:09,206 --> 00:15:11,206 Everything was going along smoothly. 176 00:15:11,206 --> 00:15:19,208 We were doing a checklist and when I got done with it, I saw the trees at the end of that checklist. 177 00:15:19,208 --> 00:15:22,209 Why then did he descend below minimums that night? 178 00:15:22,209 --> 00:15:25,209 Why did he fly that Saber liner down into the ground? 179 00:15:25,209 --> 00:15:27,210 I have no idea, really. 180 00:15:27,210 --> 00:15:30,211 I wish I could answer it, but I don't. 181 00:15:30,211 --> 00:15:34,211 It just happened and the next thing I knew we were in the trees, 182 00:15:34,211 --> 00:15:39,213 but I have no knowledge of why or no answer. 183 00:15:42,213 --> 00:15:48,215 Howard Herbst has no answer, nor do the investigators who poured over the wreckage. 184 00:15:48,215 --> 00:15:55,216 To understand how baffling this is, one must appreciate how meticulous these investigators are 185 00:15:55,216 --> 00:15:58,217 and the elaborate technology at their disposal. 186 00:15:58,217 --> 00:16:02,218 For example, they can determine 6 months after an accident 187 00:16:02,218 --> 00:16:08,220 whether or not a tiny indicator light was lit on impact. 188 00:16:08,220 --> 00:16:14,221 Electronic microscopes tell these investigators whether there are scratches on a tiny metal part, 189 00:16:14,221 --> 00:16:23,223 whether there are scratches on scratches, which might indicate a different sort of structural failure. 190 00:16:23,223 --> 00:16:29,224 A highly scientific examination of every piece of wreckage can reconstruct the state of an aircraft 191 00:16:29,224 --> 00:16:33,225 as it existed at the moment of impact. 192 00:16:38,227 --> 00:16:43,228 When the investigators finally conclude that the cause of a crash is undetermined, 193 00:16:43,228 --> 00:16:48,229 it can be assumed that the mystery is very real indeed. 194 00:16:53,230 --> 00:16:57,231 Not just civilian aircraft, but military aircraft. 195 00:16:57,231 --> 00:17:04,233 In 1956, the CF-100 was the backbone of the Royal Canadian Air Force. 196 00:17:04,233 --> 00:17:10,234 A reliable jet fighter checked out with military precision every time it left the ground, 197 00:17:10,234 --> 00:17:15,235 flown by young men with the razor-sharp reflexes of the fighter pilot. 198 00:17:22,237 --> 00:17:29,239 On May 15, 1956, a plane like this took off over the Great Lakes. 199 00:17:29,239 --> 00:17:36,240 Only seconds after its last routine transmission, it disappeared off radar. 200 00:17:36,240 --> 00:17:42,242 It was subsequently learned that the pilot had dropped 33,000 feet to his death 201 00:17:42,242 --> 00:17:47,243 without uttering a single word of distress. 202 00:17:47,243 --> 00:17:51,244 It was on that aircraft, was here the night, talking to us about it. 203 00:17:51,244 --> 00:17:54,245 In many cases, the circumstances are so mysterious 204 00:17:54,245 --> 00:17:59,246 as to give rise to theories that range from conservative scientific evaluations 205 00:17:59,246 --> 00:18:04,247 to fanciful speculations on the forces of outer and inner space. 206 00:18:04,247 --> 00:18:09,248 There appears to be, for example, a particular area of such heavy devastation 207 00:18:09,248 --> 00:18:13,249 as to be beyond the possibilities of coincidence. 208 00:18:13,249 --> 00:18:18,250 It is a line that extends curiously enough into the Bermuda Triangle. 209 00:18:18,250 --> 00:18:21,251 It is called the Agonic Line. 210 00:18:24,252 --> 00:18:28,253 The Agonic Line, or the line of zero magnetic variation, 211 00:18:28,253 --> 00:18:34,254 is the line along which magnetic north and true north are precisely the same direction. 212 00:18:34,254 --> 00:18:38,255 Now, how this would be related to a transportation accident 213 00:18:38,255 --> 00:18:43,256 or how it could cause such a tragedy has never been explained, 214 00:18:43,256 --> 00:18:48,257 but the fact remains that a number of such disasters have occurred on or near this line. 215 00:18:48,257 --> 00:18:53,259 For example, the disappearance of Northwest Airlines Flight 2501. 216 00:18:53,259 --> 00:18:56,259 The disappearance of November 212 Alpha Delta. 217 00:18:56,259 --> 00:19:00,260 The implausible last actions of the Edmund Fitzgerald. 218 00:19:00,260 --> 00:19:02,261 In searching for explanations, 219 00:19:02,261 --> 00:19:08,262 Jake Gourlet meticulously examined 86 air disasters and 45 shipping disappearances. 220 00:19:08,262 --> 00:19:15,264 In many cases, the only possible explanations seem to be outside the range of conventional wisdom. 221 00:19:15,264 --> 00:19:18,265 Some could be explained by the vortex theory, 222 00:19:18,265 --> 00:19:23,266 the so-called black holes where matter drops in and out of space-time continuum. 223 00:19:23,266 --> 00:19:28,267 Then there's the fact that the Great Lakes have heavy deposits of iron ore. 224 00:19:28,267 --> 00:19:32,268 There are well-founded theories of the magnetic field of the earth reversing itself, 225 00:19:32,268 --> 00:19:37,269 of magnetic earthquakes which could destroy navigational capabilities. 226 00:19:37,269 --> 00:19:44,271 In three cases, the disappearance of Northwest Airlines Flight 2501 over Milwaukee, 227 00:19:44,271 --> 00:19:48,272 the crash of a PA-22 into the shore ice of Lake Michigan, 228 00:19:48,272 --> 00:19:51,272 and the sudden destruction of the Edmund Fitzgerald, 229 00:19:51,272 --> 00:19:58,274 unidentified flying objects were independently and reliably reported in the disaster area. 230 00:19:58,274 --> 00:20:00,275 And so there are many theories. 231 00:20:00,275 --> 00:20:07,276 Strange atmospheric forces, electromagnetic anomalies, the agonistic line, psychic forces, 232 00:20:07,276 --> 00:20:10,277 even the presence of UFOs. 233 00:20:10,277 --> 00:20:13,278 As for my own opinion after two years of research, 234 00:20:13,278 --> 00:20:15,278 none of these theories is adequate. 235 00:20:15,278 --> 00:20:18,279 None of them is verifiable. 236 00:20:18,279 --> 00:20:20,279 Yet none can be discounted. 237 00:20:21,280 --> 00:20:24,280 Jay Gourlet continues to gather evidence, 238 00:20:24,280 --> 00:20:29,281 but as his search continues, the clues do not offer a ready explanation. 239 00:20:32,282 --> 00:20:36,283 In the heart of the Great Lakes is the mighty force of Niagara Falls, 240 00:20:36,283 --> 00:20:39,284 known as the Maid of the Mist. 241 00:20:39,284 --> 00:20:44,285 It is perhaps the most spectacular example of nature let loose. 242 00:20:44,285 --> 00:20:48,286 When men die here, there is no question as to why. 243 00:20:48,286 --> 00:20:55,288 The mystery is in the surrounding waters where there is no apparent reason for sudden death. 244 00:20:55,288 --> 00:20:59,289 Stretching out a thousand miles from the Maid of the Mist, 245 00:20:59,289 --> 00:21:03,289 the Great Lakes Triangle is joining those other areas of mystery 246 00:21:03,289 --> 00:21:07,290 that form the tragic folklore of unexplained disaster. 247 00:21:10,291 --> 00:21:19,293 Coming up next, 20th century with Mike Wallace confronts the raging inferno of volcanoes. 248 00:21:19,293 --> 00:21:23,294 Then from World War II through Korea to the supersonic marvels of today, 249 00:21:23,294 --> 00:21:28,295 weapons at war flies you through the evolution of the jet plane.
