The first one to get away

Two-thousand meters up Mount Kologet in the Kispiox Valley of northern British Columbia, the mangled and charred remains of a US B-36 bomber have sat since Feb 14, 1950, when the aircraft crashed after experiencing three catastrophic engine failures while flying a practice mission. It was no ordinary practice--the B-36 was carrying one Mk-4 atomic bomb. An expedition to the crash site of the first US broken arrow sorts through lingering questions about the fate of this atomic practice flight.
