Ammon News - On this day in 1966, Spanish authorities announced the recovery of a hydrogen bomb that had accidentally fallen into the Mediterranean several months earlier. The bomb, along with three others, had dropped from the sky after a U.S. B-52 collided with a refueling tanker over southern Spain, killing seven airmen. Two bombs exploded, a third landed intact, and the fourth simply disappeared, until officials pursued a tip from a fisherman about something hitting the water on the day of the accident. Britannica
