Google VP of Knowledge, Alan Eustace, jumped from stratosphere, 42KM (26 miles) above the sea level, in 15 minutes on Oct 24th, 2014. (Alan retired in March 2015.) This jump is in a self-sustained system, like astronaut's suit. Alan was lifted by a helium balloon and dropped with a parachute. If he used a capsule instead of a suit, he would be lifted by a lunching system. His suit is only 500 lb, but the capsule is 3000 lb.
