Aborted takeoff

The United States Air Force (USAF) Strategic Air Command (SAC) B-52D Stratofortress (serial number 55-0103) of the 4252d Strategic Wing had a full bomb load and broke up and caught fire after the aircraft aborted takeoff at Kadena Air Base while it was conducting an Operation Arc Light bombing mission to the Democratic Republic of Vietnam during the Vietnam War.[1]

Resultant fire and explosion

The fire resulting from the aborted takeoff ignited the aircraft's fuel and detonated the 30,000 lb (14,000 kg) bomb load of twenty-four 500 lb (230 kg) bombs, (twelve under each wing) and forty two 750 lb (340 kg) bombs inside the bomb bay and caused a blast so powerful that it created an immense crater under the burning aircraft some 30 ft (9.1 m) deep and 60 ft (18 m) across. The blast blew out the windows in the dispensary at Naha Air Base (now Naha Airport), 23 miles (37 km) away and damaged 139 houses.[2][3]

Recovery and investigation

The aircraft was reduced "to a black spot on the runway"[1] The blast was so large that Air Force spokesman had to announce that there had only been conventional bombs on board.[2] Nothing remained of the aircraft except landing gear and engine assemblies, the tail turret, a few bombs, and some loose explosive that had not detonated. Very small fragments of aircraft metal from the enormous blast were "spread like confetti," leaving the crew to use a double entendre to refer to the cleanup work, calling it, "'52 Pickup." The Electronic Warfare Officer and the Crew Chief later died from burn injuries after being evacuated from Okinawa. Two Okinawan workers were also injured in the blasts.[1]

Had the aircraft become airborne, it might have crashed about 1⁄4–1⁄2 mi (400–800 m) north of the runway and directly into the Chibana ammunition storage depot. The Chibana depot stored ammunition, bombs, high explosives, and tens of thousands artillery shells and is now known to have held warheads for 19 different atomic and thermonuclear weapons systems in the hardened weapon storage areas. The weapons included W28 warheads used in the MGM-13 Mace cruise missile and W31 warheads used in MGR-1 Honest John and MIM-14 Nike-Hercules (Nike-H) missiles.[4]

The storage depot at Chibana also included 52 igloos in the Project Red Hat chemical weapons storage area and presumably Project 112's biological Agents.[5][6][7][8]

The crash led to demands to remove the B-52s from Okinawa and strengthened a push for the reversion from U.S. rule in Okinawa.[1][3] Okinawans had correctly suspected that the Chibana depot held nuclear weapons. The crash sparked fears that another potential disaster on the island could put the chemical and nuclear stockpile and the surrounding population in jeopardy and increased the urgency of moving them to a less populated and less active storage location.

gollark: How did you work that out? Spending unreasonable amounts of effort to put it into a computery program?
gollark: How do you know? It might go to enjarred brain conventions.
gollark: It would still maybe be killed. It's not not mean to kill someone just because they won't feel pain.
gollark: That would be mean.
gollark: 1000V would be much rounder.
