WEBVTT 00:00:00.000 --> 00:00:01.860 You're tuned into Zero Signal Shorts, the show 00:00:01.860 --> 00:00:04.280 where we dig into the odd files, forgotten experiments, 00:00:04.419 --> 00:00:06.599 and real -world mysteries that sound too strange 00:00:06.599 --> 00:00:09.380 to be true, but are. I'm David Green, and every 00:00:09.380 --> 00:00:12.039 short episode we pull one story from the archives 00:00:12.039 --> 00:00:14.099 and break it down fast. What happened, why it 00:00:14.099 --> 00:00:16.320 mattered, and what it says about us today. If 00:00:16.320 --> 00:00:18.480 you like The Deeper Dives, remember we post our 00:00:18.480 --> 00:00:21.179 full -length episodes every Tuesday at 6 a .m. 00:00:21.280 --> 00:00:24.440 For now, let's jump into today's Signal. This 00:00:24.440 --> 00:00:26.800 one comes straight out of the 1990s Air Force 00:00:26.800 --> 00:00:29.480 lab and a memo that somehow turned into one of 00:00:29.480 --> 00:00:49.280 the weirdest headlines in military history. It 00:00:49.280 --> 00:00:51.799 may have been one of the craziest, downright 00:00:51.799 --> 00:00:56.039 laughable ideas. A so -called gay bomb. The idea 00:00:56.039 --> 00:01:00.719 was that if soldiers suddenly all became irresistible 00:01:00.719 --> 00:01:03.899 to one another, that morale and cohesion would 00:01:03.899 --> 00:01:06.280 break down and the enemy would be unable to resist. 00:01:06.579 --> 00:01:09.400 The idea of a non -lethal chemical bomb containing 00:01:09.400 --> 00:01:12.500 aphrodisiacs was among nearly 200 proposals the 00:01:12.500 --> 00:01:15.799 Pentagon received in 1994. This one from an Air 00:01:15.799 --> 00:01:18.510 Force lad in Ohio. It pitched what it called 00:01:18.510 --> 00:01:21.810 a distasteful but completely non -lethal example, 00:01:22.209 --> 00:01:25.129 especially if the chemical also caused homosexual 00:01:25.129 --> 00:01:27.890 behavior. The Defense Department says it had 00:01:27.890 --> 00:01:30.670 all the ideas reviewed and that the gay bomb 00:01:30.670 --> 00:01:33.310 proposal was among those not making the cut. 00:01:33.629 --> 00:01:35.829 The Pentagon released a statement saying it never 00:01:35.829 --> 00:01:39.069 investigated the concept, it was just one individual 00:01:39.069 --> 00:01:41.530 putting together a concept paper with a variety 00:01:41.530 --> 00:01:44.689 of examples that were rejected. But members of 00:01:44.689 --> 00:01:47.450 the California Watchdog Group's Sunshine Project 00:01:47.450 --> 00:01:50.810 don't buy that. When the Pentagon says that they 00:01:50.810 --> 00:01:53.629 rejected this proposal, it's simply not true. 00:01:53.730 --> 00:01:55.930 And we have the facts to demonstrate that they've 00:01:55.930 --> 00:01:58.530 continued to think about it and to consider it 00:01:58.530 --> 00:02:01.010 in the years since it was first raised. In San 00:02:01.010 --> 00:02:03.969 Francisco's Castro district, the idea of a gay 00:02:03.969 --> 00:02:07.250 bomb, whether considered or not, was good for 00:02:07.250 --> 00:02:09.449 some laughs. Do they really think that, like, 00:02:09.490 --> 00:02:12.349 could it be faced with, like... guns and like 00:02:12.349 --> 00:02:14.169 being killed, they're really gonna choose sex. 00:02:14.409 --> 00:02:17.509 People still have such a misunderstanding of 00:02:17.509 --> 00:02:19.889 sexuality in general, not just homosexuality, 00:02:20.030 --> 00:02:21.870 but sexuality in general, that they think that 00:02:21.870 --> 00:02:24.129 it could be used as a weapon. Like when has that 00:02:24.129 --> 00:02:27.229 ever worked? It was 1994, the middle of a strange 00:02:27.229 --> 00:02:29.270 intermission in American military history. The 00:02:29.270 --> 00:02:31.990 Cold War was over, the Soviet Union was gone, 00:02:32.009 --> 00:02:34.229 and the Pentagon was trying to figure out what 00:02:34.229 --> 00:02:36.050 comes next. The Wright Laboratory in Dayton, 00:02:36.169 --> 00:02:38.469 Ohio, an Air Force research center better known 00:02:38.469 --> 00:02:41.009 for aerodynamics and propulsion, was told to 00:02:41.009 --> 00:02:43.389 start thinking about the future of non -lethal 00:02:43.389 --> 00:02:46.090 warfare. Non -lethal was the new buzzword of 00:02:46.090 --> 00:02:48.530 the decade. Policymakers wanted weapons that 00:02:48.530 --> 00:02:51.009 could disable enemies without killing them. Something 00:02:51.009 --> 00:02:53.530 that sounded humane and politically acceptable. 00:02:53.729 --> 00:02:56.069 Inside the lab, a small team of researchers started 00:02:56.069 --> 00:02:59.080 writing a three page proposal. called harassing, 00:02:59.219 --> 00:03:01.219 annoying, and bad -guy identifying chemicals. 00:03:01.360 --> 00:03:03.319 It was a brainstorming document, a wish list 00:03:03.319 --> 00:03:05.740 of chemical tricks that might disrupt an enemy 00:03:05.740 --> 00:03:08.340 force. There were ideals about bad -smelling 00:03:08.340 --> 00:03:11.259 gases, markers that could stain uniforms, sprays 00:03:11.259 --> 00:03:13.500 that would attract stinging insects, and irritants 00:03:13.500 --> 00:03:15.819 that would make people sneeze uncontrollably. 00:03:15.879 --> 00:03:17.960 In the middle of this list was one extraordinary 00:03:17.960 --> 00:03:20.759 suggestion, a chemical that would release strong 00:03:20.759 --> 00:03:23.639 aphrodisiacs, especially if the chemical affected 00:03:23.639 --> 00:03:25.620 male behavior. It was a bureaucratic language 00:03:25.620 --> 00:03:28.030 for a wild thought that a gas bomb can make enemy 00:03:28.030 --> 00:03:30.930 soldiers too distracted, or perhaps too enamored 00:03:30.930 --> 00:03:36.770 with one another to fight. The role of base defense 00:03:36.770 --> 00:03:39.930 requires the use of non -lethal techniques, backed 00:03:39.930 --> 00:03:42.550 by the threat of lethal force. Tech Sergeant 00:03:42.550 --> 00:03:44.650 Steve German introduces us to an interesting 00:03:44.650 --> 00:03:47.370 non -lethal weapon, the active denial system. 00:03:47.759 --> 00:03:50.099 That single line would eventually become famous 00:03:50.099 --> 00:03:51.939 when the document was uncovered years later. 00:03:52.180 --> 00:03:54.560 Journalists nicknamed it the gate bomb. It is 00:03:54.560 --> 00:03:56.159 important to pause here. That was not an official 00:03:56.159 --> 00:03:58.580 name. It was never a project title or a code 00:03:58.580 --> 00:04:01.099 word. The phrase was invented by reporters and 00:04:01.099 --> 00:04:03.500 immediately recognized as offensive. It reduces 00:04:03.500 --> 00:04:06.520 sexuality as a weapon. When we use the term today, 00:04:06.599 --> 00:04:08.939 it's only as a quotation from the historical 00:04:08.939 --> 00:04:11.139 record, not an endorsement. The real story is 00:04:11.139 --> 00:04:13.219 not about sexuality. It's about the strange ways 00:04:13.219 --> 00:04:15.919 military imagination sometimes runs ahead of 00:04:15.919 --> 00:04:18.100 science and ethics. The Wright Laboratory proposal 00:04:18.100 --> 00:04:21.040 estimated a budget of $7 .5 million over six 00:04:21.040 --> 00:04:23.160 years. It was one of the dozens of non -lethal 00:04:23.160 --> 00:04:25.139 concepts floating through the Pentagon at that 00:04:25.139 --> 00:04:27.500 time. The document was typed, stamped, and filed 00:04:27.500 --> 00:04:29.779 away. Perhaps it was never discussed again. A 00:04:29.779 --> 00:04:32.240 decade later, a small watchdog organization called 00:04:32.240 --> 00:04:34.800 The Sunshine Project was investigating U .S. 00:04:35.180 --> 00:04:37.079 chemical and biological research. Through a Freedom 00:04:37.079 --> 00:04:39.399 of Information Act request, they asked for any 00:04:39.399 --> 00:04:41.600 Air Force files about non -lethal chemicals. 00:04:41.779 --> 00:04:44.160 The Air Force sent them the right lab proposal. 00:04:44.399 --> 00:04:46.420 When the Sunshine Project staff were there, they 00:04:46.420 --> 00:04:48.120 were stunned. It sounded like satire. But it 00:04:48.120 --> 00:04:50.339 was real. They scanned the pages, uploaded them, 00:04:50.420 --> 00:04:52.800 and sent copies to reporters. In 2005, the store 00:04:52.800 --> 00:04:54.579 exploded. The U .S. military once considered 00:04:54.579 --> 00:04:56.600 building a gay bomb, read the headlines. BBC 00:04:56.600 --> 00:04:59.800 News, Wired, The Guardian, and CBS all confirmed 00:04:59.800 --> 00:05:01.860 the document's authenticity. A Pentagon spokesman 00:05:01.860 --> 00:05:04.060 explained that it had never been funded, but 00:05:04.060 --> 00:05:06.339 the internet had found its next legend. To understand 00:05:06.339 --> 00:05:08.399 how anyone could have written such a proposal, 00:05:08.560 --> 00:05:10.300 we have to understand the scientific background 00:05:10.300 --> 00:05:11.959 they thought they were drawing on. During the 00:05:11.959 --> 00:05:15.100 80s and 90s, research on pheromones, the invisible 00:05:15.100 --> 00:05:17.300 chemical messengers that guide animal behavior, 00:05:17.160 --> 00:05:19.519 was everywhere. Insects and mammals were known 00:05:19.519 --> 00:05:21.579 to use pheromones for mating and territorial 00:05:21.579 --> 00:05:23.920 signals. Poplar culture seized on the discovery. 00:05:24.079 --> 00:05:26.079 Perfume companies began advertising pheromone 00:05:26.079 --> 00:05:28.819 sprays that supposedly made wearers irresistible. 00:05:28.980 --> 00:05:31.100 Lifestyle magazines published stories about the 00:05:31.100 --> 00:05:33.360 chemistry of attraction. In that climate, a military 00:05:33.360 --> 00:05:35.819 scientist looking for novel ways to disable an 00:05:35.819 --> 00:05:38.120 opponent might wonder whether chemistry could 00:05:38.120 --> 00:05:40.259 interfere with human behavior. If moths could 00:05:40.259 --> 00:05:42.839 be guided by scent, why not men? The flaw in 00:05:42.839 --> 00:05:45.079 that logic is that humans are not moths. Our 00:05:45.079 --> 00:05:47.459 organs, the structure, animals, used to detect 00:05:47.459 --> 00:05:50.000 pheromones is most vestigial. Human attraction 00:05:50.000 --> 00:05:52.579 depends on far more than smell. It's a complex 00:05:52.579 --> 00:05:55.120 cocktail of sight, voice, hormones, culture, 00:05:55.279 --> 00:05:57.399 and circumstance. Laboratory experiments with 00:05:57.399 --> 00:06:00.620 complex hormones have shown only mild and inconsistent 00:06:00.620 --> 00:06:02.899 mood changes, nothing like uncontrollable lust. 00:06:03.079 --> 00:06:04.839 Air Force researchers probably didn't know that 00:06:04.839 --> 00:06:06.879 or didn't care. The early 1990s were full of 00:06:06.879 --> 00:06:08.920 speculation, and they were tossing ideals at 00:06:08.920 --> 00:06:10.920 a wall to see what might stick. Even if the chemistry 00:06:10.920 --> 00:06:12.860 worked, the engineering wouldn't. Chemical weapons 00:06:12.860 --> 00:06:15.120 have to be delivered as fine aerosols, microscopic 00:06:15.120 --> 00:06:17.600 droplets, that drift through the air. Dispersion 00:06:17.600 --> 00:06:19.540 depends on the wind, humidity, and temperature. 00:06:19.680 --> 00:06:21.399 A 10 -mile -per -hour cross -breeze can carry 00:06:21.399 --> 00:06:23.740 a gas cloud a kilometer off target. Soldiers 00:06:23.740 --> 00:06:25.600 in the open would inhale wildly different doses. 00:06:25.720 --> 00:06:27.199 Some would breathe, though most none. Others 00:06:27.199 --> 00:06:29.620 might get sick. Realistically, a love gas would 00:06:29.620 --> 00:06:32.259 produce confusion and nausea, not romance. But 00:06:32.259 --> 00:06:34.100 that wasn't unusual for non -lethal weapons. 00:06:34.259 --> 00:06:36.180 Many ideals of that era were equally implausible. 00:06:36.300 --> 00:06:38.339 Pentagon files describe sticky foam that could 00:06:38.339 --> 00:06:40.279 trap people in place, sound weapons that could 00:06:40.279 --> 00:06:43.040 induce nausea, and maldirants designed to smell 00:06:43.040 --> 00:06:45.730 so foul that enemy troops would flee. The aphrodisiac 00:06:45.730 --> 00:06:48.790 line was just one entry among dozens of improbable 00:06:48.790 --> 00:06:50.850 chemical dreams. When the proposal surfaced publicly, 00:06:51.050 --> 00:06:53.589 the reaction mixed humor and disbelief. Journalists 00:06:53.589 --> 00:06:55.509 asked whether the Air Force had really tried 00:06:55.509 --> 00:06:57.709 to make people gay. Late night shows joked that 00:06:57.709 --> 00:07:00.110 the Pentagon wanted to weaponize fabulousness. 00:07:00.290 --> 00:07:02.350 Whatever we come up with is going to be wasteful, 00:07:02.810 --> 00:07:04.529 embarrassing to the administration and upsetting 00:07:04.529 --> 00:07:07.970 to the voters. Holy smoke. What have you got? 00:07:08.459 --> 00:07:12.360 In 1994, the Pentagon explored the possibility 00:07:12.360 --> 00:07:14.519 of a non -lethal chemical weapon that would, 00:07:14.519 --> 00:07:17.639 quote, reduce enemy soldiers' combat posture 00:07:17.639 --> 00:07:20.660 by making them totally gay bones for each other. 00:07:21.439 --> 00:07:24.449 How gay? It doesn't say. The project was abandoned 00:07:24.449 --> 00:07:26.829 in the planning stages. Of course it was. It 00:07:26.829 --> 00:07:29.149 would have been expensive, impractical, and offensive 00:07:29.149 --> 00:07:31.389 to both the red states and the gay or blue states. 00:07:31.610 --> 00:07:33.529 Within the defense community, officials wince 00:07:33.529 --> 00:07:36.009 but confirm the paperwork was authentic. They 00:07:36.009 --> 00:07:38.170 emphasize that it had never been funded, and 00:07:38.170 --> 00:07:40.050 the most brainstormed never left the proposal 00:07:40.050 --> 00:07:42.050 stage. Still, the idea was far too strange to 00:07:42.050 --> 00:07:45.250 forget. In 2007, the document even received a 00:07:45.250 --> 00:07:47.569 Nobel Peace Prize, awarded for research that 00:07:47.569 --> 00:07:49.589 first makes people laugh then makes them think. 00:07:49.689 --> 00:07:51.730 If you actually read the entire three -page memo, 00:07:51.689 --> 00:07:53.509 It's clear the writers weren't making a joke. 00:07:53.589 --> 00:07:55.970 They were following a pattern of government brainstorming 00:07:55.970 --> 00:07:57.670 that stretched back decades. During the Cold 00:07:57.670 --> 00:07:59.810 War, American intelligence agencies had experiment 00:07:59.810 --> 00:08:02.250 with every imaginable kind of behavior modification. 00:08:02.410 --> 00:08:05.350 The CIA's MK -ULTRA program had tested LSD as 00:08:05.350 --> 00:08:07.730 a true serum and dosed unwitting civilians. The 00:08:07.730 --> 00:08:10.250 Navy's Operation Sea Spray had sprayed bacteria 00:08:10.250 --> 00:08:12.649 over San Francisco to measure aerosol drift. 00:08:12.790 --> 00:08:15.350 The Army's Project Sunshine had secretly collected 00:08:15.350 --> 00:08:17.949 tissue samples from the dead to study nuclear 00:08:17.949 --> 00:08:19.970 fallout. Therefore, scientists in Dayton weren't 00:08:19.970 --> 00:08:22.389 working inside the same culture of experimentation. 00:08:22.569 --> 00:08:24.870 They weren't trying to be ridiculous. They were 00:08:24.870 --> 00:08:27.250 trying to be innovative. The absurdity only became 00:08:27.250 --> 00:08:29.149 visible in hindsight. Ethically, the proposal 00:08:29.149 --> 00:08:31.290 exposes a troubling mindset. It traced human 00:08:31.290 --> 00:08:33.590 desire as a switch to be manipulated, intimacy 00:08:33.590 --> 00:08:36.070 as a vulnerability to exploit. The assumption 00:08:36.070 --> 00:08:38.110 that sexuality could be turned into a weapon 00:08:38.110 --> 00:08:41.409 reflects the social basis for that time. In 1994, 00:08:41.509 --> 00:08:43.509 the U .S. military was operating under Don't 00:08:43.509 --> 00:08:45.950 Ask, Don't Tell, a policy that effectively silenced 00:08:45.950 --> 00:08:48.029 the gay service members. Within that culture, 00:08:48.330 --> 00:08:50.190 the ideal that same -sex attraction could be 00:08:50.120 --> 00:08:52.580 used to weaken an enemy made sense to someone 00:08:52.580 --> 00:08:54.840 on paper. Today it reads as both offensive and 00:08:54.840 --> 00:08:57.220 revealing, a snapshot of how prejudice and suede 00:08:57.220 --> 00:08:59.600 silence can blend into the batter of research. 00:08:59.759 --> 00:09:01.759 Could anything like it work today? Modern neuroscience 00:09:01.759 --> 00:09:04.139 gives us a definitive no. We know now traction 00:09:04.139 --> 00:09:06.960 is distributed across brain networks, the hypothalamus, 00:09:07.059 --> 00:09:09.460 the limbic system, the prefrontal cortex. You 00:09:09.460 --> 00:09:11.279 can influence mood with drugs or hormones, but 00:09:11.279 --> 00:09:13.980 you can't command desire. Experiments with oxytocin 00:09:13.980 --> 00:09:16.460 sprays show tiny effects on trust and empathy, 00:09:16.720 --> 00:09:18.940 not romance. Even with cutting edge tools like 00:09:18.940 --> 00:09:22.159 trans cranial stimulation, or optogenetics, scientists 00:09:22.159 --> 00:09:24.580 can only modulate emotion in lab animals under 00:09:24.580 --> 00:09:26.659 controlled conditions. Delivering such changes 00:09:26.659 --> 00:09:28.659 across the battlefield is completely science 00:09:28.659 --> 00:09:30.519 fiction. The only technologies that achieve large 00:09:30.519 --> 00:09:33.019 -scale behavior change today are digital, not 00:09:33.019 --> 00:09:35.259 chemical. Social media algorithms already influence 00:09:35.259 --> 00:09:37.720 attention, emotion, and decision -making more 00:09:37.720 --> 00:09:40.039 efficiently than any aerosol ever could. If the 00:09:40.039 --> 00:09:41.960 gay bomb represented the fantasy of controlling 00:09:41.960 --> 00:09:44.299 hearts through chemistry, the 21st century achieved 00:09:44.299 --> 00:09:46.100 it through code. The story of the gay bomb also 00:09:46.100 --> 00:09:48.659 teaches us how myths form. A single line in a 00:09:48.549 --> 00:09:50.750 technical memo became a global punchline. It 00:09:50.750 --> 00:09:52.909 spread because it combined taboo and absurdity 00:09:52.909 --> 00:09:55.330 in one irresistible package. It confirmed what 00:09:55.330 --> 00:09:57.409 people already suspected, that behind closed 00:09:57.409 --> 00:09:59.649 doors, governments fund bizarre projects and 00:09:59.649 --> 00:10:02.289 scientists sometimes lose perspective on what 00:10:02.289 --> 00:10:04.610 they're talking about. The humor made it memorable, 00:10:04.690 --> 00:10:07.470 but the laughter reminded us how power and imagination 00:10:07.470 --> 00:10:09.929 can drift into moral blind spots. But nobody 00:10:09.929 --> 00:10:12.110 asked the obvious questions, should we? In the 00:10:12.110 --> 00:10:14.710 end, the right laboratory never built its aphrodisiac 00:10:14.710 --> 00:10:16.889 bomb. The document was quietly shelved and the 00:10:16.889 --> 00:10:19.389 lab moved on to conventional research. Yet the 00:10:19.389 --> 00:10:22.110 file lives on as a parable. It shows that even 00:10:22.110 --> 00:10:24.970 at institutions obsessed with rationality, fantasy 00:10:24.970 --> 00:10:27.309 can slip through disguised as innovation. It's 00:10:27.309 --> 00:10:29.970 the same impulse that once drove the CIA to study 00:10:29.970 --> 00:10:33.110 psychic spies in the Air Force to imagine invisibility 00:10:33.110 --> 00:10:35.240 cloaks. The gay bomb is a perfect emblem. of 00:10:35.240 --> 00:10:37.440 that mindset, attempt to engineer human nature 00:10:37.440 --> 00:10:39.840 itself. When you strip away the jokes, what remains 00:10:39.840 --> 00:10:42.259 is a mirror. It reflects the fears and fantasies 00:10:42.259 --> 00:10:44.580 of a superpower trying to make war painless. 00:10:44.700 --> 00:10:47.000 It reminds us that every time humanity invents 00:10:47.000 --> 00:10:50.019 a new technology, chemical, digital, or psychological, 00:10:50.259 --> 00:10:52.539 we also invent new ways to misuse it. The real 00:10:52.539 --> 00:10:54.440 lesson of the gate bomb isn't that scientists 00:10:54.440 --> 00:10:56.480 once tried to make the soldiers fall in love. 00:10:56.580 --> 00:10:58.740 It's that the search for the control, even compassion, 00:10:58.919 --> 00:11:00.799 can become a weapon. So yes, the gate bomb was 00:11:00.799 --> 00:11:03.080 real, but only as an ideal. a footnote in a long 00:11:03.080 --> 00:11:05.320 history of military imagination. It never exploded 00:11:05.320 --> 00:11:07.539 on a battlefield, but it detonated in public 00:11:07.539 --> 00:11:10.019 consciousness, where it continues to echo. Maybe 00:11:10.019 --> 00:11:11.700 that's fitting. A bomb built from uncertainty, 00:11:11.980 --> 00:11:13.879 remembered through irony, and ultimately serving 00:11:13.879 --> 00:11:16.080 as a warning that the line between science and 00:11:16.080 --> 00:11:18.440 satire is thinner than we think. And sometimes, 00:11:18.659 --> 00:11:20.620 the strangest conspiracies are the one buried 00:11:20.620 --> 00:11:22.200 in plain sight.
