What Wikipedia says

Project Excelsior was a series of parachute jumps made by Joseph Kittinger of the United States Air Force in 1959 and 1960 from helium balloons in the stratosphere. The purpose was to test the Beaupre multi-stage parachute system intended to be used by pilots ejecting from high altitude.
