23 00:01:40,000 --> 00:01:44,000 And how did he accidentally transform the U.S. justice system? 24 00:01:48,000 --> 00:01:51,000 1859, Washington, D.C. 25 00:01:52,000 --> 00:01:56,000 New York Congressman Daniel Sickles is new to the Capitol. 26 00:01:56,000 --> 00:02:00,000 But the 39-year-old lawyer is already a powerful political insider. 27 00:02:00,000 --> 00:02:03,000 He had risen through the politics of New York City 28 00:02:03,000 --> 00:02:08,000 and was considered a protege of the sitting president, James Buchanan. 29 00:02:08,000 --> 00:02:11,000 So he was considered a guy with a big future. 30 00:02:13,000 --> 00:02:16,000 Sickles frequently entertains Washington's elite. 31 00:02:16,000 --> 00:02:20,000 At the Lafayette Square home, he shares with his young wife, Teresa. 32 00:02:21,000 --> 00:02:27,000 Teresa is a very sophisticated, well-educated, passionate Italian girl. 33 00:02:27,000 --> 00:02:33,000 The high society marriage adds glitter to Sickles' already gilded career. 34 00:02:33,000 --> 00:02:37,000 But an explosive revelation threatens to tarnish it all. 35 00:02:39,000 --> 00:02:44,000 One day in February, the congressman receives an anonymous message in the mail. 36 00:02:44,000 --> 00:02:50,000 The letter basically tells him that his wife, Teresa, is having an affair. 37 00:02:52,000 --> 00:02:57,000 What's worse, the note reveals that Teresa's lover is one of Sickles' trusted friends. 38 00:02:58,000 --> 00:03:00,000 Attorney Philip Barton Key. 39 00:03:00,000 --> 00:03:05,000 Philip Barton Key was considered one of the handsomest men in Washington society. 40 00:03:05,000 --> 00:03:11,000 He was tall, athletic, dark-haired, considered to be the best dancer in town. 41 00:03:12,000 --> 00:03:15,000 The letter describes the details of the torrid liaison, 42 00:03:15,000 --> 00:03:20,000 including the secret sign that Key uses to communicate with Teresa. 43 00:03:22,000 --> 00:03:26,000 When he was passing by the Sickles' residence in Lafayette Square, 44 00:03:26,000 --> 00:03:30,000 Key would pull out a white handkerchief and he would twirl it slowly. 45 00:03:30,000 --> 00:03:34,000 And this was supposed to be his signal to Teresa to come out and meet him. 46 00:03:35,000 --> 00:03:38,000 The news makes Sickles seethe with rage. 47 00:03:39,000 --> 00:03:43,000 His wife has betrayed him with one of his best friends, 48 00:03:43,000 --> 00:03:46,000 and apparently everybody in Washington knows about this except him. 49 00:03:47,000 --> 00:03:48,000 Teresa! 50 00:03:50,000 --> 00:03:55,000 The congressman immediately confronts his wife, who tearfully admits all. 51 00:03:56,000 --> 00:03:58,000 Sickles can barely contain himself. 52 00:04:00,000 --> 00:04:04,000 And three days later, the situation explodes. 53 00:04:05,000 --> 00:04:08,000 He looks out the window of his house, 54 00:04:08,000 --> 00:04:15,000 and Philip Barton Key is walking through Lafayette Square twirling this handkerchief. 55 00:04:17,000 --> 00:04:23,000 Moments later, Sickles grabs a gun and storms out to confront Key. 56 00:04:25,000 --> 00:04:26,000 Key! 57 00:04:26,000 --> 00:04:31,000 Sickles basically says, Key, you scoundrel, you've dishonored my house and you must die. 58 00:04:32,000 --> 00:04:33,000 Sickles! 59 00:04:33,000 --> 00:04:39,000 Key begs his friend not to pull the trigger, but the scorned husband is deaf to his cries. 60 00:04:39,000 --> 00:04:46,000 Sickles puts a gun up to Key's chest and fires literally point blank. 61 00:04:50,000 --> 00:04:51,000 Key is dead. 62 00:04:53,000 --> 00:04:54,000 Sickles! 63 00:04:54,000 --> 00:04:55,000 What have you done? 64 00:04:57,000 --> 00:05:01,000 Sickles surrenders to authorities and is charged with murder. 65 00:05:03,000 --> 00:05:07,000 There were numerous eyewitnesses, there was no doubt Sickles was guilty. 66 00:05:08,000 --> 00:05:12,000 But the clever politician cooks up a scheme to get off scot-free. 67 00:05:16,000 --> 00:05:23,000 Less than two months later, congressman Daniel Sickles stuns a Washington judge by pleading not guilty. 68 00:05:25,000 --> 00:05:31,000 Although he readily admits to firing the fatal shots, he contends that his actions didn't amount to murder. 69 00:05:32,000 --> 00:05:38,000 So the defense team put forward this argument that upon learning of the affair, Sickles' mind had become diseased. 70 00:05:38,000 --> 00:05:39,000 Key! 71 00:05:39,000 --> 00:05:40,000 Sickles! 72 00:05:42,000 --> 00:05:46,000 And that he was literally acting upon uncontrollable impulses. 73 00:05:47,000 --> 00:05:51,000 The defense declares that Sickles was temporarily insane. 74 00:05:52,000 --> 00:05:55,000 It's an argument never before presented in court. 75 00:05:55,000 --> 00:05:59,000 Yet the testimony appears to support this audacious claim. 76 00:06:00,000 --> 00:06:09,000 The defense team starts calling witnesses to the stand, who in some cases go into fairly graphic detail of what Teresa Sickles and Key were doing. 77 00:06:09,000 --> 00:06:15,000 Hearing about his wife's tawdry behavior appears to leave Sickles deranged. 78 00:06:15,000 --> 00:06:18,000 He burst into tears, he was sobbing. 79 00:06:18,000 --> 00:06:25,000 He literally had to stop the trial at one point and he was forcibly carried out of the courtroom. 80 00:06:26,000 --> 00:06:31,000 After three weeks of testimony, the case goes to the jury. 81 00:06:31,000 --> 00:06:35,000 It took them only 70 minutes to reach verdict. 82 00:06:35,000 --> 00:06:37,000 Not guilty. 83 00:06:38,000 --> 00:06:44,000 The ruling is a victory for both Sickles and his unusual defense strategy. 84 00:06:45,000 --> 00:06:57,000 He ultimately became a general in the Union Army, where he played a prominent role in a number of battles, including the Battle of Gettysburg in July 1863. 85 00:06:58,000 --> 00:07:05,000 Sickles survives the Civil War and plays a major role in establishing Gettysburg National Military Park. 86 00:07:06,000 --> 00:07:10,000 But his most lasting legacy may be his novel defense. 87 00:07:11,000 --> 00:07:20,000 Not guilty by reason of temporary insanity, which goes on to gain legitimacy in the U.S. court system and continues to be used to this day. 88 00:07:23,000 --> 00:07:33,000 The Excelsior Brigade Monument stands as a tribute to a controversial man who was unafraid to fight, both on the battlefield and in the courtroom. 89 00:07:40,000 --> 00:07:45,000 Nestled in the foothills of the San Gabriel Mountains is Arcadia, California. 90 00:07:45,000 --> 00:07:55,000 This scenic Los Angeles suburb is home to a sprawling botanical garden whose resident peacocks can sometimes be spotted wandering onto the streets. 91 00:07:58,000 --> 00:08:04,000 Yet just a cross from these tranquil grounds is an attraction that appeals to a more boisterous crowd. 92 00:08:05,000 --> 00:08:12,000 It's oval shaped and it's a mile in length. There's a grandstand, a clubhouse, a European style paddock. 93 00:08:13,000 --> 00:08:16,000 It's just a beautiful venue and it's just a beautiful place to spend a day. 94 00:08:17,000 --> 00:08:22,000 Drawing in over one million visitors each year, this is Santa Anita Park. 95 00:08:23,000 --> 00:08:30,000 From almost a century, this legendary racetrack has hosted the country's finest thoroughbreds and greatest jockeys. 96 00:08:31,000 --> 00:08:42,000 And as reporter Christina Bosenakis reveals, among them is a man with a tail so extraordinary it rocked the annals of both racing and medicine. 97 00:08:44,000 --> 00:08:51,000 This was unique, terrifying, but at the same time amazing. People still talk about it to this day. 98 00:08:51,000 --> 00:09:04,000 May 8th, 1936, San Mateo, California. The stands at the Bay Meadows Racetrack are packed for a two day tournament. 99 00:09:05,000 --> 00:09:09,000 However, the crowd's mood isn't one of excitement, but shock. 100 00:09:10,000 --> 00:09:21,000 A popular 19 year old jockey named Ralph Neves has been thrown from his horse and now lies motionless on the ground. 101 00:09:23,000 --> 00:09:28,000 It was a very dramatic scene. The track physicians were doing everything they could to try to save his life. 102 00:09:29,000 --> 00:09:31,000 The spectators watch in horror. 103 00:09:32,000 --> 00:09:44,000 Ralph Neves was a fiery, intense competitor. His nickname was the Portuguese pepper pot and he was already one of the top riders on the circuit. 104 00:09:45,000 --> 00:09:53,000 But it seems that Neves' career has come to an end. After repeated attempts to resuscitate him, doctors give up. 105 00:09:54,000 --> 00:09:58,000 Neves' body is loaded onto a stretcher and transported to the local hospital. 106 00:09:58,000 --> 00:10:06,000 And the announcer told the crowd, we regret to inform you that Ralph Neves is dead. Please stand in silent prayer. 107 00:10:08,000 --> 00:10:13,000 The crowd was absolutely stunned. This was an awful accident and loss of life. 108 00:10:14,000 --> 00:10:19,000 Though the mood is grim, track officials decide to carry on with the event. 109 00:10:20,000 --> 00:10:32,000 But that's not the end of the athlete's tragic tale. Soon after Neves' arrival at the hospital, an attendant enters the room where his motionless body has been placed. 110 00:10:33,000 --> 00:10:35,000 Only to make a shocking discovery. 111 00:10:36,000 --> 00:10:40,000 To his surprise, the stretcher that Ralph Neves was on was found empty. 112 00:10:43,000 --> 00:10:45,000 The body is no longer there. 113 00:10:50,000 --> 00:11:02,000 It's 1936 in San Mateo, California. Celebrated jockey Ralph Neves is pronounced dead following a horrific accident on the track. 114 00:11:03,000 --> 00:11:07,000 But after his body is taken to the mortuary, it mysteriously disappears. 115 00:11:10,000 --> 00:11:17,000 Back at the Bay Meadows track, the crowd is still reeling from the tragedy when they hear a sudden commotion. 116 00:11:19,000 --> 00:11:23,000 A frantic, half-dressed figure is running onto the race course. 117 00:11:25,000 --> 00:11:30,000 To everyone's amazement, it is none other than the fallen jockey Ralph Neves. 118 00:11:32,000 --> 00:11:39,000 People couldn't even believe what they were seeing. Ralph Neves was back on the track running around and he was alive. 119 00:11:41,000 --> 00:11:44,000 Neves insists he's fit to ride. 120 00:11:45,000 --> 00:11:52,000 And incredibly, race officials eventually agree to let him participate in the remainder of the two-day event. 121 00:11:53,000 --> 00:11:56,000 Neves' incredible resurrection stuns the crowd. 122 00:11:57,000 --> 00:12:06,000 In less than 24 hours after being pronounced dead, Ralph Neves won the riding title at Bay Meadows and was awarded $500 and a gold watch. 123 00:12:07,000 --> 00:12:14,000 So how did the Portuguese pepperpot apparently come back from the dead? 124 00:12:16,000 --> 00:12:27,000 It is later revealed that when the jockeys seemingly lifeless body arrived at the morgue, a grief-stricken friend who was a doctor at the hospital rushed in to pay his final respects. 125 00:12:28,000 --> 00:12:37,000 So he sees Neves and whether it was because it's his friend, whether he just had an instinct, he decided to check for a pulse. 126 00:12:39,000 --> 00:12:43,000 And to the doctor's amazement, there was a glimmer of a pulse. 127 00:12:44,000 --> 00:12:52,000 Believing the unconscious jockey could still be saved, the physician reportedly administered a shot of adrenaline directly to Neves' heart. 128 00:12:53,000 --> 00:13:00,000 And Neves miraculously sits up and comes back to life. 129 00:13:02,000 --> 00:13:07,000 Before the stunned doctor could say a word, the jockey rushed out the door. 130 00:13:08,000 --> 00:13:12,000 Neves galed a taxi and demanded to be taken back to the racetrack. 131 00:13:13,000 --> 00:13:20,000 Ralph Neves goes on to enjoy a long and prolific racing career. 132 00:13:21,000 --> 00:13:29,000 And in 1954, the Santa Anita Park presents him with one of the sport's highest honors, the George Wolf Award. 133 00:13:30,000 --> 00:13:35,000 Throughout his career, Ralph Neves won over 3700 victories. 134 00:13:35,000 --> 00:13:47,000 Today, the Santa Anita Park stands as a reminder of the jockey who crossed life's finish line, not once, but twice. 135 00:13:51,000 --> 00:13:52,000 Paris, France. 136 00:13:54,000 --> 00:13:58,000 The legendary Latin Quarter is home to one of the world's oldest universities. 137 00:13:59,000 --> 00:14:08,000 And also at the heart of this scholarly district stands another imposing edifice that celebrates the country's greatest minds. 138 00:14:09,000 --> 00:14:21,000 It's 350 feet long, 275 feet high with 22 Corinthian columns, and inside are frescoes and statues honoring France's great heroes. 139 00:14:22,000 --> 00:14:35,000 This is the Pantheon, final resting place of the philosopher Voltaire, scientist Marie Curie, and writer Jean-Jacques Rousseau. 140 00:14:36,000 --> 00:14:47,000 But as author Andrew Rosgineau knows, this palatial mausoleum also houses the tomb of a lesser known Frenchman who enlightened a once powerless population. 141 00:14:48,000 --> 00:14:52,000 He may not be a household name, but his invention spread throughout the globe. 142 00:14:52,000 --> 00:14:59,000 Who is this man? And how is his ingenious creation essential to millions of lives around the world? 143 00:15:01,000 --> 00:15:04,000 1812, Couvet, France. 144 00:15:06,000 --> 00:15:11,000 In this small country village outside of Paris, daily life holds few surprises. 145 00:15:12,000 --> 00:15:18,000 Yet for three-year-old Louis Brie, every moment is filled with intrigue and wonder. 146 00:15:19,000 --> 00:15:23,000 Louis was curious and creative. He was really interested in how the world works. 147 00:15:25,000 --> 00:15:31,000 Louis' favorite place to explore is the shop where his father makes harnesses for horses. 148 00:15:31,000 --> 00:15:37,000 Louis loved nothing more than to go to work with his father. Every day he would go in there and sit and watch his father and his work. 149 00:15:38,000 --> 00:15:47,000 The back-breaking job involves punching hundreds of holes into leather strips, using a hammer and a sharp instrument known as an awl. 150 00:15:48,000 --> 00:15:52,000 Louis' father expressly forbids him from playing with the dangerous tools. 151 00:15:54,000 --> 00:16:00,000 But one day, when the harness maker's back is turned, the curious boy sees a chance to handle the instruments. 152 00:16:01,000 --> 00:16:06,000 He tries as much as he can and musters all of his energy to put holes into the leather. 153 00:16:07,000 --> 00:16:10,000 But he's unable to get the sharp point to go through. 154 00:16:11,000 --> 00:16:13,000 Then suddenly, Louis loses his grip. 155 00:16:16,000 --> 00:16:18,000 The tool slips and goes into his left eye. 156 00:16:20,000 --> 00:16:28,000 Despite the efforts of local doctors, the wound develops into a raging infection that spreads to Louis' right eye. 157 00:16:28,000 --> 00:16:31,000 Unfortunately, the damage is irreversible and Louis becomes blind. 158 00:16:32,000 --> 00:16:34,000 The affliction is devastating. 159 00:16:35,000 --> 00:16:40,000 At the time, French schools are simply not equipped to educate blind children. 160 00:16:41,000 --> 00:16:44,000 So in the early 19th century, to be blind was to have no future. 161 00:16:45,000 --> 00:16:49,000 Most people that were blind at the time had lives as beggars in the streets. 162 00:16:50,000 --> 00:16:53,000 Louis knows this cruel fate may also await him. 163 00:16:56,000 --> 00:16:59,000 But seven years later, he's thrown what seems like a lifeline. 164 00:16:59,000 --> 00:17:06,000 A local priest secures a scholarship for him at the Royal Institute for Blind Youth in Paris. 165 00:17:07,000 --> 00:17:11,000 This was the only school of its kind, not only in France, but in the world. 166 00:17:12,000 --> 00:17:17,000 The elite academy offers classes ranging from math to science to music. 167 00:17:17,000 --> 00:17:22,000 Louis' imagination runs wild. He's picturing a library full of books, row after row after row. 168 00:17:23,000 --> 00:17:29,000 But when the ambitious boy arrives at the institute, he is sorely disappointed. 169 00:17:29,000 --> 00:17:34,000 He discovers that the school has just three books for blind readers. 170 00:17:34,000 --> 00:17:37,000 The existing technology to make books for the blind was called embossing, 171 00:17:37,000 --> 00:17:42,000 which was a process of pressing lead into wax paper in order to create raised letters 172 00:17:42,000 --> 00:17:45,000 that you would have to trace with your finger in order to read. 173 00:17:46,000 --> 00:17:51,000 The embossed type is so oversized that a single sentence is a single sentence 174 00:17:51,000 --> 00:17:56,000 that a single sentence often takes up an entire page, making reading laborious. 175 00:17:58,000 --> 00:18:06,000 Not only that, but fabricating such enormous books is so costly that precious few have ever been produced. 176 00:18:07,000 --> 00:18:13,000 This system had flaws. Louis realizes the current technologies that exist for the blind are not sufficient. 177 00:18:14,000 --> 00:18:16,000 Louis comes to a heartbreaking conclusion. 178 00:18:16,000 --> 00:18:23,000 Unless a better way to educate the blind is found, they are destined to remain on the fringes of society. 179 00:18:24,000 --> 00:18:27,000 In that moment, Louis realizes he's the one that's going to have to do this himself. 180 00:18:35,000 --> 00:18:41,000 It's the 1820s in France. Blind teenager Louis Bray is desperate to learn, 181 00:18:41,000 --> 00:18:47,000 but the system in place for teaching the blind how to read and write is woefully subpar. 182 00:18:47,000 --> 00:18:51,000 So what game-changing alternative is he about to invent? 183 00:18:54,000 --> 00:18:56,000 Couvret, France 184 00:18:56,000 --> 00:19:00,000 School is out of session and Louis has returned to his parents' village for the summer. 185 00:19:01,000 --> 00:19:07,000 But while the other children are playing outdoors, Louis spends most of his time in his father's harness shop. 186 00:19:08,000 --> 00:19:16,000 One morning, he picks up the awl, the very tool that injured him, and grips it in his hand like a pencil. 187 00:19:18,000 --> 00:19:20,000 Suddenly, inspiration strikes. 188 00:19:21,000 --> 00:19:28,000 Louis realizes that he can use this very same tool to poke dots into paper to create letters of the alphabet. 189 00:19:29,000 --> 00:19:33,000 But instead of recreating the large, embossed letters of his school books, 190 00:19:33,000 --> 00:19:37,000 the boy translates the alphabet into a simple code. 191 00:19:38,000 --> 00:19:43,000 Like a domino, Louis' system involved a series of dots, two by three. 192 00:19:43,000 --> 00:19:46,000 Each letter represented by one to six dots. 193 00:19:47,000 --> 00:19:52,000 To Louis' delight, his compact new system is much easier to read. 194 00:19:52,000 --> 00:19:56,000 Each letter could be read by a single finger as he moved it across the page. 195 00:19:56,000 --> 00:20:01,000 And he even had configurations for music, numbers and punctuations. 196 00:20:01,000 --> 00:20:08,000 Best of all, he knows that such a simplified code will finally make books for the blind more cost-effective to print. 197 00:20:10,000 --> 00:20:15,000 Louis presents his invention to his classmates, and it rapidly gains traction. 198 00:20:15,000 --> 00:20:19,000 Eventually, the French government would adopt the system and it would spread throughout the globe. 199 00:20:19,000 --> 00:20:25,000 This truly was now giving blind people the same access to knowledge that the side had had. 200 00:20:25,000 --> 00:20:32,000 To properly honor the 15-year-old student who created it, Louis' writing system is named after him. 201 00:20:33,000 --> 00:20:39,000 Even to this day, the code is called Braille, the English pronunciation of Louis' French name, Braille. 202 00:20:43,000 --> 00:20:51,000 200 years after his landmark invention, a bust of Louis Braille appears alongside his tomb at the Pantheon. 203 00:20:51,000 --> 00:20:57,000 A marble tribute to the man who delivered the world's knowledge to those who could not see it. 204 00:21:00,000 --> 00:21:07,000 Wyoming covers almost 100,000 square miles and is the 10th largest state in the Union. 205 00:21:07,000 --> 00:21:16,000 But despite its massive size, the 44th state has one of the smallest populations, a mere 500,000 people. 206 00:21:16,000 --> 00:21:23,000 But one imposing feature of this vast landscape now brings in just as many tourists. 207 00:21:23,000 --> 00:21:31,000 It's over a thousand feet high and the first thing you see about it is it's just covered with these vertical lines. 208 00:21:31,000 --> 00:21:35,000 Nature has been working on this a long time. 209 00:21:35,000 --> 00:21:37,000 This is Devil's Tower. 210 00:21:37,000 --> 00:21:44,000 In 1906, the striking monolith was declared America's first, and it was the first to be built. 211 00:21:44,000 --> 00:21:48,000 The first was declared America's first national monument. 212 00:21:48,000 --> 00:21:56,000 But according to author Mark O'Connell, it owes its popularity to one man's obsession with the unknown. 213 00:21:56,000 --> 00:22:04,000 His work propelled the popularity of Devil's Tower to unparalleled heights and made us wonder whether we were really alone in the universe. 214 00:22:05,000 --> 00:22:10,000 1966, Wright-Patterson Air Force Base, Ohio. 215 00:22:11,000 --> 00:22:18,000 Dr. J. Allen Heineck is a well-respected astronomer and scientific advisor for the U.S. Air Force. 216 00:22:18,000 --> 00:22:28,000 With UFO sightings on the rise, Heineck has been charged with squashing the public's growing fear by any means necessary. 217 00:22:28,000 --> 00:22:34,000 The Air Force employed him as a debunker. He was proud of that and he went after it with great relish. 218 00:22:34,000 --> 00:22:42,000 Heineck's job is to convince the public that UFOs don't exist and that sightings are a result of natural causes. 219 00:22:42,000 --> 00:22:47,000 To this end, he has developed an arsenal of excuses. 220 00:22:47,000 --> 00:22:53,000 Dr. Heineck's job was to look at every UFO sighting report that came in and say, 221 00:22:53,000 --> 00:22:59,000 no, we can set this one aside. That was clearly the planet Venus. That was clearly a meteor. 222 00:22:59,000 --> 00:23:05,000 There was one case where Heineck says, oh, that was an atmospheric eddy, but there was no such thing as an atmospheric eddy. 223 00:23:05,000 --> 00:23:08,000 It was something Heineck just made up for that case. 224 00:23:08,000 --> 00:23:12,000 But his life is about to be flipped upside down. 225 00:23:13,000 --> 00:23:20,000 On March 23rd, Heineck is sent to investigate a high-profile sighting in southwest Michigan. 226 00:23:20,000 --> 00:23:27,000 Once he arrives, the skeptical scientist speaks to a local resident who claims to have witnessed the event. 227 00:23:28,000 --> 00:23:35,000 A farmer in southern Michigan reported seeing a lighted craft land in the swamp north of his farmhouse. 228 00:23:35,000 --> 00:23:39,000 It hovered, it moved up and down, and side to side. 229 00:23:39,000 --> 00:23:44,000 But the farmer wasn't the only one to observe strange lights in the night sky. 230 00:23:44,000 --> 00:23:50,000 An entire sorority at a nearby college claims to have seen something similar. 231 00:23:50,000 --> 00:23:56,000 87 residents of a dorm watched very similar lights hovering in the arboretum outside the building. 232 00:23:56,000 --> 00:24:03,000 By the end of his visit, Heineck has interviewed over 100 people, including local police. 233 00:24:03,000 --> 00:24:08,000 They all confirm that they saw something in the skies over the town. 234 00:24:08,000 --> 00:24:12,000 It's then that Heineck has an epiphany. 235 00:24:12,000 --> 00:24:19,000 He started to wonder whether this case was credible. He realized that it was wrong to treat these people like they were kooks. 236 00:24:19,000 --> 00:24:25,000 Back at his hotel, Heineck starts to think about his previous cases from the past two decades. 237 00:24:27,000 --> 00:24:36,000 Heineck had spent an awful lot of time investigating some extremely strange UFO cases that had been reported by some extremely normal people. 238 00:24:36,000 --> 00:24:43,000 It really caused him to question his assumptions and think long and hard what had really happened to these people. 239 00:24:43,000 --> 00:24:48,000 It seemed clear to him that there was something more to this phenomenon than anyone had originally suspected. 240 00:24:48,000 --> 00:24:57,000 The former skeptic now unequivocally believes that the lights in Michigan could actually be evidence of something otherworldly. 241 00:24:57,000 --> 00:25:01,000 Heineck decides he needs to do something. 242 00:25:01,000 --> 00:25:07,000 What Dr. Heineck really wanted was a serious scientific study of the phenomenon. 243 00:25:08,000 --> 00:25:14,000 For the first time in 20 years, Heineck proposes to his boss, Major Hector Quintanilla, 244 00:25:14,000 --> 00:25:20,000 that supposed UFO sightings deserve serious scientific study. 245 00:25:20,000 --> 00:25:23,000 But he is immediately rebuked. 246 00:25:23,000 --> 00:25:32,000 Hector Quintanilla had made it very clear to Heineck that he had to come up with an explanation quickly and that it had to be natural causes. 247 00:25:32,000 --> 00:25:38,000 Vowing to pressure from his boss, Heineck reluctantly prepares a report. 248 00:25:38,000 --> 00:25:45,000 In it, he dismisses the mysterious sightings as nothing more than swamp gas. 249 00:25:45,000 --> 00:25:50,000 But the residents of Southwest Michigan don't buy it. 250 00:25:50,000 --> 00:25:55,000 An angry and confused public demands a more thorough investigation into the sightings. 251 00:25:55,000 --> 00:26:01,000 And Heineck is ordered to make a statement at a congressional hearing. 252 00:26:01,000 --> 00:26:06,000 So with the nation and the Air Force watching, what will Heineck say? 253 00:26:10,000 --> 00:26:20,000 It's 1968. UFO debunker Jay Allen Heineck has spent the last 20 years convincing the American public that aliens do not exist. 254 00:26:20,000 --> 00:26:25,000 But he's recently come to the stunning realization that maybe they do. 255 00:26:25,000 --> 00:26:32,000 Now he faces a congressional hearing. Will Dr. Heineck reveal his extraterrestrial epiphany? 256 00:26:34,000 --> 00:26:38,000 When the congressional hearing convenes, Heineck is called to the stand. 257 00:26:38,000 --> 00:26:41,000 I have a dossier of 20 particularly… 258 00:26:41,000 --> 00:26:48,000 In his statement, Heineck's proposal was to take the investigation of UFO cases out of the Air Force's hands 259 00:26:48,000 --> 00:26:53,000 and put it in the hands of scientific teams at universities across the country. 260 00:26:53,000 --> 00:26:58,000 It is a landmark moment and the press goes wild. 261 00:26:58,000 --> 00:27:02,000 The fiasco made Heineck a superstar. 262 00:27:02,000 --> 00:27:05,000 But his superiors aren't so impressed. 263 00:27:05,000 --> 00:27:09,000 They were furious with Heineck for making that statement. 264 00:27:09,000 --> 00:27:14,000 In the wake of Heineck's rogue statement, Project Blue Book is terminated. 265 00:27:14,000 --> 00:27:18,000 And with it, his role in the U.S. Air Force. 266 00:27:19,000 --> 00:27:25,000 Undeterred, in 1972, Heineck writes a book titled The UFO Experience. 267 00:27:25,000 --> 00:27:28,000 And in it, he coins a new term. 268 00:27:29,000 --> 00:27:34,000 Dr. Heineck introduced a new categorization system for UFO experiences. 269 00:27:34,000 --> 00:27:37,000 He identified them as close encounters. 270 00:27:37,000 --> 00:27:42,000 Today, the phrase is synonymous with extraterrestrial activities. 271 00:27:42,000 --> 00:27:49,000 A close encounter of the first kind involves visual contact with an object less than 500 feet away. 272 00:27:49,000 --> 00:27:54,000 A close encounter of the second kind includes physical effects. 273 00:27:54,000 --> 00:27:58,000 So this could mean that a UFO causes a car's engine to die. 274 00:27:58,000 --> 00:28:03,000 A close encounter of the third kind involves occupants of the UFO 275 00:28:03,000 --> 00:28:07,000 and possible interaction between the occupants and the human witness. 276 00:28:08,000 --> 00:28:12,000 Heineck's book becomes a runaway bestseller. 277 00:28:12,000 --> 00:28:18,000 And in 1977, the now infamous term finds its way to the silver screen. 278 00:28:18,000 --> 00:28:25,000 As the inspiration for Steven Spielberg's blockbuster hit Close Encounters of the Third Kind. 279 00:28:26,000 --> 00:28:31,000 For the location of the film's finale, the director casts Devil's Tower 280 00:28:31,000 --> 00:28:35,000 as the site of the climactic extraterrestrial encounter. 281 00:28:35,000 --> 00:28:40,000 In the movie, several UFO contactees become obsessed with this image 282 00:28:40,000 --> 00:28:46,000 and then they become obsessed with getting to where this image is, which is Devil's Tower in Wyoming. 283 00:28:46,000 --> 00:28:53,000 In a fitting nod of appreciation and respect, Spielberg even gives Dr. Heineck a cameo in the film. 284 00:28:54,000 --> 00:29:01,000 And today, the iconic peak of Devil's Tower stands as a magnificent testament to mother nature 285 00:29:01,000 --> 00:29:09,000 and a reminder of one man who risked his livelihood in the pursuit of ideas that were truly out of this world. 286 00:29:11,000 --> 00:29:18,000 The New York City neighborhood of Harlem is a world-renowned hub of African-American art and culture 287 00:29:18,000 --> 00:29:22,000 thanks to the great migration of the early 20th century. 288 00:29:22,000 --> 00:29:28,000 During this time, more than 6 million people fled the South in search of a better life. 289 00:29:29,000 --> 00:29:36,000 But standing on the north end of Fifth Avenue is an obelisk that commemorates a group of black Americans 290 00:29:36,000 --> 00:29:39,000 who traveled far beyond the nation's borders. 291 00:29:39,000 --> 00:29:48,000 It's 12 feet tall, 3 feet at the base, it's black granite, and like the men that it honors, this monument is largely unknown. 292 00:29:49,000 --> 00:29:53,000 This is the 369th Infantry Regiment Memorial. 293 00:29:54,000 --> 00:30:04,000 According to author Max Brooks, the soldiers immortalized here pushed themselves to the limit during an epic struggle for honor and equality. 294 00:30:05,000 --> 00:30:11,000 In spite of tremendous adversity, this unit helped define a war, an army, and a nation. 295 00:30:16,000 --> 00:30:19,000 April 1917, France. 296 00:30:20,000 --> 00:30:23,000 World War I is raging. 297 00:30:23,000 --> 00:30:29,000 America has just joined the Allies in the global conflict, and not a moment too soon. 298 00:30:30,000 --> 00:30:35,000 By 1917, the British were teetering on the edge of exhaustion. 299 00:30:35,000 --> 00:30:37,000 The French Army was at the end of its rope. 300 00:30:37,000 --> 00:30:42,000 The question was, could the United States marshal enough men to save the Allies? 301 00:30:43,000 --> 00:30:54,000 General Jack Pershing, commander of the American forces in Europe, calls on President Woodrow Wilson to send him one million troops. 302 00:30:54,000 --> 00:31:00,000 And by December, thousands of American soldiers have landed on French soil. 303 00:31:00,000 --> 00:31:03,000 Among them is the 369th Infantry. 304 00:31:05,000 --> 00:31:10,000 They are the first black combat soldiers America has ever deployed overseas. 305 00:31:10,000 --> 00:31:15,000 But while these men may be new to Europe, they are no strangers to conflict. 306 00:31:16,000 --> 00:31:25,000 Back in the U.S., where segregation and racial violence against African Americans is rampant, they live under constant threat of attack. 307 00:31:26,000 --> 00:31:33,000 The conventional wisdom in 1917 among white Americans was that the African American was a lesser breed of human. 308 00:31:34,000 --> 00:31:39,000 But by fighting for their country, the young men see an opportunity to finally prove their worth. 309 00:31:40,000 --> 00:31:43,000 As black men, they wanted to prove themselves to their community. 310 00:31:43,000 --> 00:31:48,000 And as Americans, they wanted to prove that they had a right to share in the American dream. 311 00:31:49,000 --> 00:31:54,000 Yet the Army's high command crushes their aspirations before they had their chance. 312 00:31:55,000 --> 00:32:01,000 The top brass thought that the 369th were not worthy of the battlefield. 313 00:32:01,000 --> 00:32:07,000 This unit was kept completely separate from whites, and they were made to do manual labor. 314 00:32:08,000 --> 00:32:16,000 Instead of heading to the front lines, the 369th are put to work unloading ships in French ports. 315 00:32:17,000 --> 00:32:20,000 These were combat troops. They were trained to go into the trenches. 316 00:32:21,000 --> 00:32:25,000 And to suddenly be made to offload ships could not have been a greater insult. 317 00:32:26,000 --> 00:32:33,000 The mood was grim. The mood was angry. They were described as orphans left on the stoop of France. 318 00:32:34,000 --> 00:32:39,000 So will the 369th infantry ever get their chance to fight? 319 00:32:44,000 --> 00:32:47,000 It's 1918 and World War I is raging. 320 00:32:48,000 --> 00:32:55,000 When an all-African-American unit is sent to Europe, they see it as an opportunity to prove themselves as first-rate soldiers. 321 00:32:56,000 --> 00:32:59,000 But upon arriving in France, they're told they're not allowed to fight. 322 00:32:59,000 --> 00:33:04,000 So will these men get the chance to show the world what they're truly made of? 323 00:33:08,000 --> 00:33:13,000 The 369th fear they'll be relegated to the sidelines for the rest of the war. 324 00:33:14,000 --> 00:33:20,000 But then they get some unexpected news. Not from the American Army, but from the French. 325 00:33:21,000 --> 00:33:23,000 The French were desperate for anybody who would help them. 326 00:33:24,000 --> 00:33:28,000 Suddenly there was a unit of American troops that was willing to get into combat, and the French didn't think twice. 327 00:33:29,000 --> 00:33:30,000 They took them with open arms. 328 00:33:31,000 --> 00:33:33,000 It's the chance they've been waiting for. 329 00:33:34,000 --> 00:33:38,000 They were given French helmets, French gear, French rifles. 330 00:33:39,000 --> 00:33:46,000 In September of 1918, the 369th Regiment arrives on the front lines in northeastern France. 331 00:33:47,000 --> 00:33:51,000 The battle they fight comes to be known as the Muse Argonne Offensive, 332 00:33:52,000 --> 00:33:56,000 an arduous campaign to push enemy forces out of France for good. 333 00:33:56,000 --> 00:34:02,000 It was a bloodbath. They had to endure shell fire. They had to endure machine guns. 334 00:34:03,000 --> 00:34:05,000 They had to endure poison gas. 335 00:34:06,000 --> 00:34:12,000 Day after day, the men of the 369th Regiment bravely risk their lives. 336 00:34:13,000 --> 00:34:20,000 You have men charging into shell fire and never retreating, never losing a foot of ground, never losing a man to capture. 337 00:34:21,000 --> 00:34:28,000 The soldiers are so ferocious and unyielding on the battlefield that the enemy even gives them a nickname. 338 00:34:30,000 --> 00:34:34,000 The Germans out of fear called them the Harlem Hellfighters. 339 00:34:36,000 --> 00:34:39,000 This was the unit you did not want to cross. 340 00:34:41,000 --> 00:34:48,000 And in November of 1918, Germany surrenders to the Allies, signaling the end of World War I. 341 00:34:49,000 --> 00:34:54,000 The Harlem Hellfighters set out to prove their mettle in combat, and they did it with honor. 342 00:34:55,000 --> 00:34:58,000 They became one of the most decorated regiments in the entire U.S. Army. 343 00:35:00,000 --> 00:35:03,000 Reports of their fearless feats make it back to America. 344 00:35:04,000 --> 00:35:08,000 And in February of 1919, the men return home as heroes. 345 00:35:09,000 --> 00:35:13,000 Over a million New Yorkers lined Fifth Avenue to welcome them back. 346 00:35:19,000 --> 00:35:28,000 While a long fight for civil rights still lay ahead, the men of the 369th Infantry Regiment took a courageous and historic step forward. 347 00:35:29,000 --> 00:35:35,000 The road to equality is made up of many stones, and one of those stones was laid by the Harlem Hellfighters. 348 00:35:36,000 --> 00:35:51,000 And this monument, commemorating the Harlem Hellfighters, stands as a fitting testament to a brave group of men who battled hatred on two continents and emerged victorious. 349 00:35:55,000 --> 00:36:03,000 The town of Wyndham, Connecticut was once home to the largest thread mill in North America, hence its nickname Thread City. 350 00:36:04,000 --> 00:36:14,000 But just downriver from the former mill's waterfall, a collection of unusual landmarks spins a far more chilling tale from the region's earliest days. 351 00:36:15,000 --> 00:36:23,000 They're 11 feet tall, they're blue-green, they're made of bronze, and they have huge bulging golden eyes that are a little bit creepy. 352 00:36:24,000 --> 00:36:28,000 And when you see these things, you wonder, what are they doing on the bridge? 353 00:36:28,000 --> 00:36:39,000 This quartet of four-legged amphibians holds court on each end of the Thread City crossing, a 500-foot bridge that spans the Willimantic River. 354 00:36:40,000 --> 00:36:50,000 And as author S. E. Schlosser can attest, these beguiling statues speak of a harrowing incident that left the people of Wyndham hopping with fright. 355 00:36:50,000 --> 00:36:57,000 There was a tale of terror that left a peaceful community convinced that they were on the brink of destruction. 356 00:37:01,000 --> 00:37:10,000 Wyndham, Connecticut, 1754. This agrarian community of 1,000 English settlers has fallen on hard times. 357 00:37:11,000 --> 00:37:19,000 It is in the throes of a parching drought, and the people live in constant fear of being attacked by neighboring Native Americans. 358 00:37:20,000 --> 00:37:23,000 If Wyndham had been attacked at this time, period, they wouldn't have survived. 359 00:37:24,000 --> 00:37:30,000 To protect the town from this grim fate, local lawyer Colonel Elephant Dyer forms a plan. 360 00:37:31,000 --> 00:37:40,000 Dyer was very aware that the town was vulnerable to a possible attack, so he started recruiting for militia out of the farmers and the other workers in his community at the time. 361 00:37:41,000 --> 00:37:45,000 And the Ragtag Group will be called into action sooner than they think. 362 00:37:46,000 --> 00:37:52,000 One night in June, the settlers are asleep when a strange chorus pierces the night. 363 00:37:53,000 --> 00:37:56,000 This sound comes out of nowhere. 364 00:37:57,000 --> 00:38:05,000 It was thunderous. It was shrieking and screaming and roaring. It woke everyone up in town. 365 00:38:05,000 --> 00:38:15,000 They think the Indians must be massed outside our village, and this is a huge battle cry just before they come and kill us all in our beds. 366 00:38:16,000 --> 00:38:18,000 The villagers descend into all-out panic. 367 00:38:19,000 --> 00:38:25,000 Women were screaming, and little kids started crying. People were huddling in their beds. They were diving for cover. 368 00:38:26,000 --> 00:38:30,000 As the townsfolk cry out in terror, Dyer quickly assembles his men. 369 00:38:30,000 --> 00:38:37,000 The militia are grabbing any kind of weapon they can get their hands on. Pitchforks, guns, rolling pins, whatever they can get. 370 00:38:38,000 --> 00:38:43,000 They brace for the onslaught. But the attack never comes. 371 00:38:44,000 --> 00:38:47,000 They're exhausted from terror, and nothing's happened. 372 00:38:48,000 --> 00:38:54,000 By morning, the horrific cries have died down, but the villagers still don't know if they're safe. 373 00:38:54,000 --> 00:38:59,000 So Colonel Dyer forms a posse and sets off into the woods to investigate. 374 00:39:01,000 --> 00:39:08,000 They're looking behind every rock, every tree, and every shrub expecting to find warriors waiting to attack, and there's no one there. 375 00:39:09,000 --> 00:39:14,000 They are totally baffled. What in the world is going on? Where's the enemy? 376 00:39:15,000 --> 00:39:23,000 But a few miles out of town, as the men near the crest of a hill, the bizarre cross, the men are all in the same place. 377 00:39:24,000 --> 00:39:26,000 The cries return. 378 00:39:28,000 --> 00:39:31,000 They think they're about to be attacked or terrified. 379 00:39:38,000 --> 00:39:47,000 It's 1754 in Connecticut. The villagers of Wyndham are searching for a tribe of Native Americans who they believe were shouting battle cries during the night. 380 00:39:48,000 --> 00:39:52,000 But what's really behind these mysterious nocturnal noises? 381 00:39:55,000 --> 00:40:02,000 As Dyer and his men creep up the hill towards the source of the noise, they brace themselves for battle. 382 00:40:04,000 --> 00:40:08,000 But when they reach the peak, they encounter an eerie sight. 383 00:40:10,000 --> 00:40:15,000 They get to the top. There's nothing there. No enemy. 384 00:40:17,000 --> 00:40:20,000 Instead, all they see is a half-empty pond. 385 00:40:21,000 --> 00:40:26,000 As they're walking towards the pond, they look down and look around. 386 00:40:28,000 --> 00:40:35,000 They see hundreds and hundreds of dead bullfrogs all over the ground. 387 00:40:37,000 --> 00:40:42,000 And the frogs that are still alive are making a kind of roaring sound at each other. 388 00:40:44,000 --> 00:40:47,000 The embarrassed militia men breathe a sigh of relief. 389 00:40:51,000 --> 00:40:59,000 But the question remains, why are there so many dead frogs? 390 00:41:00,000 --> 00:41:13,000 The theory is that because of the drought, many colonies of frogs from several areas all decided that night to migrate to the only source of water that was left in the area, which was this mill pond. 391 00:41:14,000 --> 00:41:22,000 Windomites believe that when there wasn't enough water to satisfy the frenzied mob, a massive and deadly battle ensued. 392 00:41:23,000 --> 00:41:33,000 Their battle cries, multiplied by hundreds and hundreds of frogs coming from many directions, were what caused this huge sound that seemed to surround the town. 393 00:41:34,000 --> 00:41:42,000 Two hundred and sixty years later, the legacy of a bullfrog battle endures as a piece of local folklore. 394 00:41:44,000 --> 00:41:53,000 They actually put the frog on their town's seal. When they were minting their own money, they had pictures of the battling frogs on their one dollar bill. 395 00:41:54,000 --> 00:41:58,000 And they've even created monuments to the frogs at each corner of the bridge. 396 00:41:58,000 --> 00:42:12,000 And so today, these whimsical frog sculptures greet visitors to Windom, a reminder of the case of mistaken identity that terrified an entire town. 397 00:42:15,000 --> 00:42:22,000 From a jilted spouse to a resurrected jockey, a blind inventor to a bullfrog battle. 398 00:42:22,000 --> 00:42:27,000 I'm Don Wildman and these are the Mysteries at the Monument.
