Above is an image of a downed blimp, or barrage balloon, that was floated above the Nevada Test Site to measure the effects of the pressure wave from a nuclear blast. The test was a nineteen kiloton detonation codenamed Stokes, part of the series Operation Plumbbob, and was set off about five miles away from the blimp. That was today in 1957.
