1953 ... Shot: Grable (Atomic Cannon)

... 15 kiloton at 525 feet... "These clips are from shot Grable, the Atomic Cannon test in 1953 showing the initial burst and shockwave. Identified also are the various vehicles on the desert floor which are very, very tiny compared to the fireball of the blast. There are cars, jeeps, buses and tanks under the blast area."
