When a Dropped Socket Threatened Nuclear Armageddon

追加: 2026-05-30

[00:00:00]September 18th, 1980.

[00:00:02]An 8-lb socket slips off the tool and falls 80 ft into the darkness of the silo. Below sits a rocket with a 9-megaton warhead.

[00:00:12]In 9 hours, one of the four people in this bunker will be dead. Official reports will call it human error.

[00:00:20]They won't be lying, but they won't [music] tell the whole story.

[00:00:28]What happens when America's most secure bunker turns into a trap from the inside?

[00:00:34]The man who can stop this is already [music] on base, but no one will ask him.

[00:00:40]David Powell and Jeffrey Plumb descend into the silo. It's a standard mission, a pressure check on the oxidizer tank.

[00:00:48]Air Force regulations require a torque wrench.

[00:00:51]Powell grabs a heavy ratchet instead. 25 lb, 3 ft long.

[00:00:56]The correct tool is back in the truck.

[00:01:00]But [snorts] Powell is in a escape suit.

[00:01:02]The way back is across the entire complex.

[00:01:06]He decides not to turn back.

[00:01:10]>> [snorts] >> The silo, nine stories of reinforced concrete.

[00:01:14]Inside stands the Titan II.

[00:01:17]The fuel tanks are made of aircraft-grade aluminum. The walls are thinner than a penny.

[00:01:23]Only internal pressure holds the structure together.

[00:01:27]On top sits the W53 warhead, nine megatons, 600 times more powerful than Hiroshima.

[00:01:37]Therefore, every operation inside this silo has exactly one allowed scenario.

[00:01:43]Deviations from protocol don't get a second chance here.

[00:01:48]Powell stands on the upper platform, reaches for the valve.

[00:01:52]The 8-lb socket detaches from the tool.

[00:01:56]It falls 80 ft through the narrow gaps, bounces off a rubber spacer, smashes into the first stage hull.

[00:02:04]A direct hit on the Aerozine 50 fuel tank.

[00:02:08]Aerozine 50 doesn't need a spark. It ignites instantly upon contact with the oxidizer.

[00:02:14]The tank is pierced.

[00:02:16]Fuel sprays out under pressure.

[00:02:19]The silo begins to fill with toxic vapor from the bottom up.

[00:02:23]In the control center, the alarm blares.

[00:02:26]The commander's first documented reaction to Powell's report, verbatim, "Uh-oh."

[00:02:35]930 mi away, a man who has never seen a Titan II up close just picked up the phone.

[00:02:43]The protocol existed. The tool existed.

[00:02:47]There was only one decision, and they failed to make it 3 seconds before it was too late.

[00:02:55]Who runs the operation when there is no protocol?

[00:03:00]All personnel at site 374-7 have been evacuated.

[00:03:05]A perimeter is established. Police are forcibly removing civilians within a 5-mi radius.

[00:03:11]People are told to leave immediately.

[00:03:14]Don't even lock your doors.

[00:03:17]Inside the silo, only the damaged rocket remains.

[00:03:21]The concentration of Aerozine 50 vapors grows with every minute.

[00:03:30]930 mi away, at Strategic Air Command headquarters in Omaha, Lieutenant General Lloyd Leavitt approaches the console. He takes command of the operation over the phone. Leavitt has never worked with Titan II rockets, not for a single day, but he is now the one determining every next step.

[00:03:51]Jeff Kennedy is standing at the perimeter. Kennedy is one of the top Titan II technicians on the entire base.

[00:03:59]While headquarters in Omaha looks for a precedent, there is no protocol for a massive leak in a closed silo. Kennedy has already run the numbers. He knows where the valves are. He knows the pressure. He knows exactly how much time is left before the point of no return.

[00:04:16]So, he tries to fight his way through to command. They tell him to wait. Hours pass. Levitt holds meetings over the phone. Pump water into the silo.

[00:04:26]Stabilize the pressure. Try the ventilation. Kennedy hears these plans and flags one detail that none of those plans account for. The ventilation system at site 374-7 is not blast proof. But, the order is not open for discussion. Meanwhile, Rex Huckle and Greg Devlin receive a mission that doesn't exist in any manual. They have to get inside the locked complex through an emergency hatch. The electronic lock is no longer responding.

[00:04:57]In their hands, they have a crowbar and hammers. Two US officers are breaking into their own secret nuclear facility.

[00:05:06]So, at 10:00 p.m., Washington joins the operation.

[00:05:10]Vice President Walter Mondale, at a Democratic National Convention in Little Rock, just 50 miles from the silo, asks one question over a secure channel.

[00:05:21]Is there a nuclear weapon on board?

[00:05:24]The answer is delayed.

[00:05:26]At that same convention is the governor of Arkansas, Bill Clinton.

[00:05:31]He is 50 miles away from a silo with a 9-megaton warhead, where a fuel tank has been breached and toxic steam has been leaking for 6 hours straight.

[00:05:41]Neither of them knows just how close this has come. At 2:00 a.m., Levitt finally makes a decision.

[00:05:48]Kennedy and 22-year-old Airman David Livingston are ordered to enter the vapor zone.

[00:05:54]Before going in, Kennedy stops. He says to Livingston quietly, "I have a bad feeling about this.

[00:06:01]Somebody is going to die tonight." Then he takes a step and goes in first.

[00:06:08]The man with the answer stood at the perimeter.

[00:06:11]The man without experience held the phone.

[00:06:15]Between them, 930 miles and the chain of command.

[00:06:23]What happens when you send a man where no one is allowed to go?

[00:06:27]What they find after the blast will not appear in any official report the next morning.

[00:06:35]Sergeant Jeff Kennedy and Senior Airman David Livingston put on their escape suits.

[00:06:40]Full chemical protection. Zero blast protection.

[00:06:44]None.

[00:06:46]Inside, visibility is zero.

[00:06:50]Instruments show that Aerozine 50 concentration has long since exceeded all survival limits.

[00:06:58]Kennedy and Livingston move by touch through the fog. They take measurements.

[00:07:03]They head back to the surface.

[00:07:05]They report their findings.

[00:07:08]But, Leavitt has already made the next decision.

[00:07:11]Over the radio comes the order. Turn on the exhaust fan.

[00:07:17]Kennedy knows what that means. The silo is filled with Aerozine 50 vapors to a critical level.

[00:07:24]The fan is not blast proof. Its contact group is a standard electrical circuit.

[00:07:29]Activating the motor creates a spark.

[00:07:32]Just one spark.

[00:07:35]So, the order is not open for discussion. Livingston approaches the switch.

[00:07:41]Spark.

[00:07:43]Detonation.

[00:07:45]Power, several tons of TNT.

[00:07:48]A reactive jet of fire blasts upward through the silo. The 740-ton concrete lid is blown into the night sky and lands 650 ft away.

[00:07:59]Kennedy is thrown 150 ft from the entrance. Severe fractures. He is alive.

[00:08:06]Livingston is caught in the epicenter.

[00:08:08]Tons of concrete and steel.

[00:08:12]>> Uh all the time that I'm walking I can hear them say "Oh my god, help me."

[00:08:19]"Please, somebody help me."

[00:08:23]Because of my leg being broken I determined that I could not get him.

[00:08:30]>> Sergeant Roberts finds him in the chaos of smoke and fire.

[00:08:34]Livingston is conscious. He cannot move.

[00:08:37]Roberts picks him up in his arms. He carries him 100 yd through the toxic cloud like a child.

[00:08:45]Livingston dies in the hospital later that day.

[00:08:48]Pulmonary edema from nitrogen tetroxide vapors.

[00:08:52]He was 22 years old.

[00:08:54]Before they entered the vapor, Jeff Kennedy had turned to his partner and said "Someone's going to die tonight."

[00:09:02]He was right.

[00:09:03]But he didn't know he was predicting the death of the man standing right next to him.

[00:09:09]That was the last piece of accurate information command received that night.

[00:09:14]The silo is burning. Rescue teams cannot get close. Secondary explosions, toxic smoke, nitric acid instead of water.

[00:09:25]But the biggest problem of the night is no longer in the silo.

[00:09:29]It's gone.

[00:09:32]Livingston shouldn't have been there that night.

[00:09:35]He volunteered.

[00:09:37]The order that killed him came from a man 930 mi away.

[00:09:44]Where is the 9 megaton warhead now?

[00:09:48]The Pentagon will find it.

[00:09:50]But the question of who pays for this night will remain open for a long time.

[00:09:56]The explosion threw the nose cone of the rocket along with the W53 warhead into the air.

[00:10:02]The warhead's mass, 8,000 lb.

[00:10:05]Where it landed, a man.

[00:10:08]US troops are scouring the fields in the dark.

[00:10:11]Flashlights, Geiger counters, thick toxic smoke.

[00:10:15]No coordinates.

[00:10:17]When Vice President Mondale asks again over the secure channel about the status of the nuclear charge, command stalls again.

[00:10:26]But they find the warhead a few hours after the blast.

[00:10:31]It is lying in the roadside ditch near the main gates of the complex.

[00:10:35]8,000 lb in a standard ditch.

[00:10:39]External dents, no detonation.

[00:10:43]Why didn't it blow?

[00:10:45]To initiate a W53, the conventional explosives around the plutonium core had to detonate simultaneously at all points with microsecond precision.

[00:10:56]The electrical circuits of the arming system were physically disconnected. The rocket was in standby mode.

[00:11:03]But experts later admitted the W53 was one of the least safe warheads in the US arsenal.

[00:11:11]It did not have insensitive high explosives, material that won't detonate from impact or fire.

[00:11:18]If the impact factor had hit the detonators directly, there was a real risk of a massive plutonium dispersal over Arkansas.

[00:11:27]So, between that night and radioactive contamination for thousands of years, there stood exactly one thing.

[00:11:35]The angle the warhead hit the ditch.

[00:11:39]Not the system.

[00:11:40]Not the protocol.

[00:11:42]The angle.

[00:11:44]Warhead found, silo destroyed, one man dead. The Pentagon begins an investigation.

[00:11:52]And now, the system must answer one question.

[00:11:55]Who is to blame?

[00:11:57]The answer is already ready.

[00:12:00]It doesn't involve the generals.

[00:12:06]The system failed.

[00:12:08]Who answered for it?

[00:12:10]The answer to that question will take several months.

[00:12:13]The result can be predicted from the first page of the investigation.

[00:12:17]The Pentagon forms a commission. The investigation takes months. The commission looks for the start point, the moment where the system broke.

[00:12:26]They find the ratchet.

[00:12:29]David Powell, the 21-year-old technician who took the wrong tool, becomes the central figure of the blame.

[00:12:36]The Air Force applies Article 15, non-judicial punishment, discharge from the service.

[00:12:43]But, the investigation doesn't stop at the ratchet. It goes further, to the fern, to the order, to the man who gave that order.

[00:12:53]Lieutenant General Lloyd Leavitt.

[00:12:56]The man who ran the operation over the phone. The man who had never worked with Titan II's. The man whose order to turn on a non-blast-proof fan in a silo with a critical concentration of vapors directly initiated the detonation.

[00:13:14]His career did not suffer. Kemedy got a medal, then a reprimand.

[00:13:20]Same night, same actions, same envelope.

[00:13:24]Powell got Article 15, told no one for 35 years. Not colleagues, not friends, not his mother.

[00:13:34]When he closes his eyes, he still sees it falling. The 8-lb socket, 80 ft of darkness, the sound of impact.

[00:13:44]>> I hear a song on the radio.

[00:13:46]I'll see something on TV, and bam, there it is. It's back, you know.

[00:13:55]It's very hard to talk about even today.

[00:13:58]I uh tried to live as normal a life as I can.

[00:14:04]And uh and uh but there isn't a day goes by that I don't think about it.

[00:14:10]30, whatever, 35 years, whatever it's been.

[00:14:15]Every day.
