On January 24, 1961, a B-52 bomber experienced a mid-air breakup over Goldsboro, North Carolina, due to a fuel leak. This incident led to the release of two hydrogen bombs that were part of its payload.
Five of the eight crew members successfully bailed out, while three were killed in the crash.
First Warhead
The first hydrogen bomb landed in a field with its parachute deployed, resulting in a relatively soft impact. This warhead was equipped with six interlocking safety mechanisms designed to prevent detonation. A 1969 report by nuclear safety supervisor Parker F. Jones stated that five of these six interlocks were activated by the fall. A single remaining switch prevented the 24-megaton bomb from detonating.
Second Warhead
The second hydrogen bomb impacted a muddy field, creating a 1.5-meter hole. During its recovery, which took three days, investigators found that its safety switch was set to "Armed." The conclusion drawn by investigators was that the impact itself shifted the switch to "Armed" but simultaneously damaged the circuits necessary for detonation. Major components of this bomb remain buried in the field.
Aftermath
Experts concluded that a detonation of either bomb could have eliminated a city of approximately 30,000 people. The US government compensated the farmer with $100 for a 61-meter radius section of the farm. Agricultural use of the land is permitted, but digging beyond five feet is prohibited in that area.
