A picture taken in 1971 shows a nuclear explosion in Mururoa atoll. A sign marks the plane crash that caused two nuclear bombs to fall in North Carolina. Mars Bluff Incident: The US Air Force Accidentally Dropped a Nuclear Bomb on South Carolina Starting in the late 1940s and running through to the end of the Cold War, an arms race occurred. Before coming in for a landing at Seymour Johnson Air Force Base in the populated Goldsboro, the pilot decided to keep flying in an attempt to burn off some gas an action he likely hoped would help prevent the plane from exploding if the risky landing should go wrong. Ironically, it appears that the bomb that drifted gently to earth posed the bigger risk, since its detonating mechanism remained intact. Despite decades of alarmist theories to the contrary, that assessment was probably correct. They point out that the arm-ready switch was in the safe position, the high-voltage battery was not activated (which would preclude the charging of the firing circuit and neutron generator necessary for detonation), and the rotary safing switch was destroyed, preventing energisation of the X-Unit (which controlled the firing capacitors). The atomic bomb dropped on Hiroshima in World War II had a yield of about 16 kilotons. When the second tanker arrived to meet up with the B-47, the bomber was nowhere to be found. The parachute opened on one; it didnt on the other. It took a week for a crew to dig out the bomb; soon they had to start pumping water out of the site. While many drive past the site of the 'Nuclear Mishap' every day without even realizing it, there are some scars remaining from that chilling night. The wing was failing and the plane needed to make an emergency landing, soon. Second, the bomb landed in a mostly empty field. Examination of the bombs mechanism revealed it had completed several automated steps toward detonation, but experts disagree on just how close it came to exploding. Five crewmen ejected and one climbed out a hatch, watching from their parachutes as the B-52 literally broke apart in the air. Sixty years ago, at the height of the Cold War, a B-52 bomber disintegrated over a small Southern town. Within an hour, in the early morning of January 24, a military helicopter was hovering overhead. The role of the bomber was to see if these kinds of planes could perform bomb runs in extremely cold weather. Eight crew were aboard the gas-guzzling B-52 bomber during a routine flight along the Carolina coast that fateful night. Then, at 4:19 p.m., a member of the crew aboard a U.S. Air Force B-47E bomber accidentally released a nuclear weapon that landed on the girls' playhouse and the family's nearby garden, creating a massive crater with a circumference of 50 feet (15 meters) and depth of 35 feet (10 meters). But it didnt, thanks to a series of fortunate missteps. It produced a giant explosion, left a 3.5-meter (12 ft) deep crater, and spread radioactive contaminants over a 1.5-kilometer (1 mi) area. It is, without a doubt, the most mysterious incident of its kind. He was a very religious man, Dobson says. He said, 'Not great. On that night in 1961, the bomber carrying these nukes sprung a mysterious fuel leak. After searching for more than 10 minutes, he pulled himself up to look over the bomb's curved belly. Why didn't the bombs explode? In 1961, as John F. Kennedy was inaugurated, Cold War tensions were running high, and the military had planes armed with nuclear weapons in the air constantly. What the voice in the chopper knew, but Reeves didnt, was that besides the wreckage of the ill-fated B-52, somewhere out there in the winter darkness lay what the military referred to as broken arrowsthe remains of two 3.8-megaton thermonuclear atomic bombs. The mission was supposed to be pretty simpledeliver a load of unarmed AGM-129 ACM cruise missiles to a weapons graveyard. The Mark 6 bomb that fell onto this remote area of South Carolina weighed 7,600 pounds (3.4 metric tons) and was 10 feet, 8 inches (3.3 meters) long. And within days of accidentally dropping a bomb on U.S. soil, the Air Force published regulations that locking pins must be inserted in nuclear bomb shackles at all times even during takeoff and landing. Thats a question still unanswered today.

Mars Bluff isnt a sprawling metropolis with millions of people and giant skyscrapers. [3] The third pilot of the bomber, Lt. Adam Mattocks, is the only person known to have successfully bailed out of the top hatch of a B-52 without an ejection seat. The tip was barely dug into the ground.. As with the British Columbia incident, the bomb was inactive but still had thousands of pounds of explosives. This is the second of three broken arrow incidents that year, this time taking place in the waters off Tybee Island near Savannah, Georgia. While its unclear how frequently these types of accidents have occurred, the Defense Department has disclosed 32 accidents involving nuclear weapons between 1950 and 1980. Even now, over 55 years after the accident, people are still looking for it. Fuel was leaking from the planes right wing. This material may not be published, broadcast, rewritten or redistributed. [4] In contrast the Orange County Register said in 2012 (before the 2013 declassification) that the switch was set to "arm", and that despite decades of debate "No one will ever know" why the bomb failed to explode. Consider supporting our work by becoming a member for as little as $5 a month. His only chance was to somehow pull himself through a cockpit window after the other two pilots had ejected. Ten B-29 bombers were loaded with one nuclear weapon each. When a military crew found the bomb, it was nose-down in the dirt, with its parachute caught in the tree, still whole. The plot is still farmed to this day. He was heading straight for the burning wreckage of the B-52. With a maximum diameter of 61 inches (1.5 meters), the Mark 6 had an inflated, cartoon-like quality, reminiscent of something Wile E. Coyote would order from the ACME Co. Its capabilities, however, were no laughing matter. On January 21, 1968, a B-52 bomber carrying four hydrogen bombs was flying over Baffin Bay in Greenland when the cabin caught fire. A similar incident occurred just a month before the South Carolina accident, when a midair collision between a bomber and a fighter jet on a training mission caused a "safed" hydrogen bomb to fall near Savannah, Georgia. The bombing by American forces ended the second world war. The demon core that killed two scientists, what happens when a missile falls back into its silo, the underground test that didnt stay that way, supposed to be ready to respond to a nuclear attack, had to start pumping water out of the site. He seized on that moment to hurl himself into the abyss, leaping as far from the B-52 as he could. That sign, a small patch of trees, and some discolored dirt in a field are the only reminders of the fateful night that happened exactly 62 years ago today. On the other hand, I know of at least one medical doctor who was considering moving to Goldsboro for a position, but was concerned that it might not be safe because of the Goldsboro broken arrow. [11], Former military analyst Daniel Ellsberg has claimed to have seen highly classified documents indicating that its safe/arm switch was the only one of the six arming devices on the bomb that prevented detonation. [18], Lt. Jack ReVelle, the bomb disposal expert responsible for disarming the device, determined that the ARM/SAFE switch of the bomb which was hanging from a tree was in the SAFE position. "Long-term cancer rates would be much higher throughout the area," said Keen. Which travel companies promote harmful wildlife activities? Their garden ceased to exist; the playhouse seemed to have disappeared into thin air, save a small piece of tin from the roof; and the family home sat at a tilted angle, no longer flush with the foundation, surrounded by parts of itself. [12][b][4], The second bomb plunged into a muddy field at around 700 miles per hour (310m/s) and disintegrated without detonation of its conventional explosives. The nuclear components were stored in a different part of the building, so radioactive contamination was minimal. Add a Comment. "It could have easily killed my parents," said U.S. Air Force retired Colonel Carlton Keen, who now teaches ROTC at Hunt High School in Wilson. A Warner Bros. Crash of a United States Air Force bomber carrying nuclear warheads in North Carolina. What was not so standard was an accidental collision with an F-86 fighter plane, significantly damaging the B-47s wing. the bomb's nuclear payload wasn't armed . So sad.. This is one of the most serious broken arrows in terms of loss of life. It contains 400 pounds (180kg) of conventional high explosives and highly enriched uranium. The incident that happened in Palomares, Spain on January 17, 1966 was a bad one, even for a broken arrow. Most of the thermonuclear stage of the bomb was left in place, but the "pit", or core, containing uranium and plutonium which is needed to trigger a nuclear explosion was removed. So far, the US Department of Defense recognizes 32 such incidents. In the planes flailing descent, the bomb bays opened, and the two bombs it was carrying fell to the ground. During the flight, the bomber was supposed to undergo two aerial refueling sessions. But one of the closest calls came when an America B-52 bomber dropped two nuclear bombs on North Carolina. Declassified documents that the National Security Archive released this week offered new details about the incident. However, when the B-52 reached its assigned position, the pilot reported that the leak had worsened and that 37,000 pounds (17,000kg) of fuel had been lost in three minutes. I had a fix on some lights and started walking.. The Reactor B at Hanford was used to process uranium into weapons grade plutonium for the Fat Man atomic bomb that was dropped on Nagasaki (Credit: Alamy) "The effects are medical, political . Due to the harsh weather conditions, three of the six engines failed. As the plane broke apart, the two bombs plummeted toward the ground. The Royal Navy organized extensive searches assisted by French and Moroccan troops stationed in the area. The accident happened when a B-52 bomber got into trouble, having embarked from Seymour Johnson Air Force base in Goldsboro for a routine flight along the East Coast. Theyre sobering examples of how one tiny mistake could potentially cause massive unintentional damage. As the pilot lost control, two hydrogen bombs separated from the plane, falling to the North Carolina fields below. The 12-foot (4 m) long Mark 15 bomb weighs 7,600 pounds (3,400kg) and bears the serial number 47782. The site where one of the atomic bombs fell is marked today by an unusual patch of trees standing in the middle of an otherwise unassuming field. Thousands could have died in the blast and following radioactive cloud, especially depending on which direction the winds blew. And I said, "Great." However, the military wasnt actually planning to nuke anybody, so the bomb didnt contain the plutonium core necessary for a nuclear detonation. The impact of the crash put it in the armed setting. When they found that key switch, it had been turned to ARM. At about 2:00 a.m., an F-86 fighter collided with the B-47. Well, Lord, he said out loud, if this is the way its going to end, so be it. Then a gust of wind, or perhaps an updraft from the flames below, nudged him to the south. Eco-friendly burial alternatives, explained. Largely hidden behind woods, walls, and wetlands, the base has been an unobtrusive jobs-and-money community asset since World War II. The incident was less dramatic than the Mars Bluff one, as the bomb plunged into the water off the coast of nearby Tybee Island, damaging no property and leaving no visible impact crater. One landed in a riverbed and was fineit didnt leak; it didnt explode. 2.

They had no idea that five years later, they would earn the dubious honor of being the first and only family to survive the first and only atomic bomb dropped on American soil by Americans. He told me he just looked around and said, Well, God, if its my time, so be it. When does spring start? It had been "safed" for transport, meaning that the radioactive part of the bomb's payload was removed and was being moved in a different plane. The fake story spread widely via social media.[12]. In what would eventually get dubbed Thulegate, it came out that the Danish government was secretly allowing the stockpiling of nuclear weapons on its soil during peacetime. At this moment, it looked like that chance assignment would be his death warrant. There is some uncertainty as to which of the two bombs was closest to detonation, as different sources contradict one another over this point. The crew was forced to bail out, but they first jettisoned the Mark IV and detonated it over the Inside Passage in Canada. To protect the aircrew from a possible detonation in the event of a crash, the bomb was jettisoned. Piecing together a giant prehistoric rhinoceros is as hard as it looks. How did this mountain lion reach an uninhabited island? Each contained more firepower than the combined destructive force of every explosion caused by humans from the beginning of time to the end of World War II. We didnt ask why. [8], Starting on February 6, 1958, the Air Force 2700th Explosive Ordnance Disposal Squadron and 100 Navy personnel equipped with hand-held sonar and galvanic drag and cable sweeps mounted a search. The refueling was aborted, and ground control was notified of the problem. The blast today, with populations in the area at their current level, would kill more than 60,000 people and injure more 54,000, though the website warns that calculating casualties is problematic, and the numbers do not include those killed and injured by fallout. (Related: I trekked to a nuclear crater to see where the Atomic Age first began.). Sign up for our newsletter and enter to win the second edition of our book. "So it can't go high order or reach radioactive mass.". Lulu. The tritium reservoir used for fusion boosting was also full and had not been injected into the weapon primary. Only a small dent in the earth, the Register reports, revealed its location. Weapon 2, the second bomb with the unopened parachute, landed in a free fall. Shortly after takeoff, one of the planes developed engine trouble. Fortunately once again it damaged another part of the bomb needed to initiate an explosion. Another fell in the sea and was recovered a few months later. Above the whomp-whomp of the blades, an amplified voice kept repeating the same word: Evacuate!, We didnt know why, Reeves recalls. Offer subject to change without notice. The officer in charge came and gave a quick inspection with a passing glance at the missiles on the right side before signing off on the mission. Then, for reasons that remain unknown, the bombs safety harness failed. Jamie founded Listverse due to an insatiable desire to share fascinating, obscure, and bizarre facts. The bomb was jettisoned over the waters of the Savannah River. Fortunately, the safing pins that provided power from a generator to the weapon had been yanked preventing it from going off. Michael H. Maggelet and James C. Oskins (2008). Firefighters hose down the smoking wreckage of a B-52 Stratofortress near Faro, North Carolina, in the early morning hours of January 24, 1961. A dozen of them were loaded onto a B-52, six on each side. Illustration: Ada Amer/Background image: Public Domain. [1] A Boeing B-52 Stratofortress carrying two 34-megaton Mark 39 nuclear bombs broke up in mid-air, dropping its nuclear payload in the process. [5] As noted in the Atomic Energy Commission "Form AL-569 Temporary Custodian Receipt (for maneuvers)", signed by the aircraft commander, the bomb contained a simulated 150-pound (68kg) cap made of lead. Winner will be selected at random on 04/01/2023. Even so, when word got out, the public was quite distressed to find out exactly how easily six incredibly dangerous nuclear weapons can get misplaced through simple error. Unauthorized use is prohibited. Why didn't the area sink into a nuclear winter, and why not rope off South Carolina for the next several decades, or replace the state flag's palmetto tree with a mushroom cloud? The military does have a tendency to lose a nuclear weapon every now and then without ever recovering it. Two pieces of good news came after this. An eyewitness recalls what happened next. The crew didnt find every part of the bomb, though. That is not the case with this broken arrow. This Greenland incident, commonly referred to as the Thule accident, took place just two years after Palomares and has a lot of similarities with the previous broken arrow. Looking up at that gently bobbing chute, Mattocks again whispered, Thank you, God!. However, he said, "We have rigorous protocol in place to prevent anything like this from remotely happening.". My mother was praying. Greenland is a territory administered by Denmark, and the country had implemented a nuclear-free policy in 1957. Other than that one, theres never been another military crash around here., "Course," he adds, "the one accident we did have dropped a couple of atom bombs on us", Copyright 1996-2015 National Geographic SocietyCopyright 2015-2023 National Geographic Partners, LLC. The bomb landed on the house of Walter Gregg. Check out the other articles in the series: The demon core that killed two scientists, missing nuclear warheads, what happens when a missile falls back into its silo, and the underground test that didnt stay that way. They were Mark-39 hydrogen thermonuclear bombs. Even so, it still had about 2,250 kilograms (5,000 lb) of regular explosives, so the Mark IV could still create a huge explosion. The Goldsboro incident was first detailed last year in the book Command and Control by Eric Schlosser. Broken arrows are nuclear accidents that dont create a risk of nuclear war. If the nuclear components had been present, catastrophe would have ensued. In January, a jet carrying two 12-foot-long Mark 39 hydrogen bombs met up with a refueling plane, whose pilot noticed a problem. But by far the most significant remnant of that calamitous January night still lies 180 feet or so beneath that cotton field. On a January night in 1961, a U.S. Air Force bomber broke in half while flying over eastern North Carolina. The bomb's detonation leveled nearby pine trees and virtually destroyed the Gregg residence, shifting the house off of its foundation. Another five accidents occurred when planes were taxiing or parked. "These nuclear bombs were far more powerful than the ones dropped in Japan.". The B-52 crash was front-page news in Goldsboro and around the country. "Not too many would want to.". The crew did not see an explosion when the bomb struck the sea. It started flying through the seven-step sequence that would end in detonation. Then they began having electrical problems. The aircraft, a B-52G, was based at Seymour Johnson Air Force Base in Goldsboro. In fact, accidents like that at Mars Bluff caused the Air Force to make changes. The first recorded American military nuclear weapon loss took place in British Columbia on February 14, 1950. [1] It was carrying a single 7,600-pound (3,400kg) bomb. On this very day 62 years ago, history in North Carolina was almost irreparably changed when two nuclear bombs fell from a crashing military airplane, landing in a field near Goldsboro. The device fell through the closed bomb bay doors of the bomber, which was approaching Kirtland at an altitude of 520 metres (1,700 ft).
