December 1965. In heavy seas, an A-4 Skyhawk carrying a B43 nuclear weapon is rolled across the deck of an American carrier. One wheel slips. Aircraft, pilot and weapon go over the edge into five kilometres of water — and the world will not learn about it for years.
This evidence-led investigation follows the Cold War "Broken Arrow" accidents: the Ticonderoga loss and the map correction that turned it into a diplomatic problem with Japan; the 1950 B-36 that jettisoned a Mark 4 with no plutonium core installed; the B-47 that vanished over the Mediterranean with two nuclear capsules and left no wreckage at all; Tybee Island, where ten weeks of searching found nothing and the rumours never stopped; and Palomares, the case that proved recovering the hardware does not rewind the event.
We are careful about the difference between "a bomb was lost" and "a bomb could detonate" — they are not the same sentence. The United States has acknowledged 32 serious nuclear-weapon accidents between 1950 and 1980, none of which produced an accidental nuclear detonation. That is a real safety achievement. It is not proof the accidents were harmless.
Where the record says "probably" — as with the USS Scorpion's torpedoes — this video says "probably" too.
