SA-2 Saturn I lifting off from LC-34 at Cape Canaveral, Florida. This was the first flight of Project Highwater, which was carried on SA-2 through SA-4.

"This vehicle had a secondary mission. After the first stage shutoff, at a 65-mile altitude, the water-filled upper stage was exploded, dumping 95 tons of water in the upper atmosphere. The resulting massive ice cloud rose to a height of 90 miles. The experiment, called Project Highwater, was intended to investigate the effects on the ionosphere of the sudden release of such a great volume of water."
