A B-52 tore apart over North Carolina in January 1961 and dropped two hydrogen bombs, and Sandia’s own accident reports, released in 2021, record that one bomb powered itself up, ran its timer out and crushed its nose on impact, and that an arm-safe switch left on safe was the reason it did not detonate
Two February 1961 Sandia Corporation reports, released under a Freedom of Information Act request in 2021, one for the first time and the other with far less blacked out, walk through the wreckage component by component. On the bomb whose parachute opened, the batteries fired, the barometric switch closed, the timer ran its cycle out and the nose crushed on impact. Two switches had never been moved, and the second stayed safe only because the first did.
