A B-36 Bomber accidentally drops a 10-megaton bomb over Albuquerque, New Mexico (1957)
I looked this up yesterday - this was a non-nuclear detonation of a Mark 17 Hydrogen Bomb, just a little ways away from Kirtland AFB outside Albuquerque. The bomber was on approach, transporting the weapon from Biggs AFB in Texas.
Per normal takeoff/landing procedure, the locking pin was removed so that the device could be jettisoned if an emergency arose. Turns out the trigger for release was also inadvertently pulled by some means, dropping the device through the bottom of the plane, leaving a gaping hole (similar to the accidental drop over Mars Bluff, SC almost 10 months later.)
The detonation of the conventional explosives aboard the bomb left a crater 25 feet wide and 12 feet deep. The non-critical fissile material scattered over a much smaller area than a cow that happened to be nearby - the only casualty of the incident.
Here is an interesting narrative of the event and the general cold war atmosphere by someone who was in school in Albuquerque at the time of the detonation.
