“What you guys doing?”
“Oh nothing, just waiting FOR AN ATOMIC BOMB TO EXPLODE ABOVE OUR HEADS!”
On July 19, 1957, five men stood at Ground Zero of an atomic test that was being conducted at the Nevada Test Site. This was the test of a 2KT (kiloton) MB-1 nuclear air-to-air rocket launched from an F-89 Scorpion interceptor. The nuclear missile detonated 10,000 ft above their heads.
A reel-to-reel tape recorder was present to record their experience. You can see and hear the men react to the shock wave moments after the detonation.
