For his supersonic freefall attempt, Baumgartner will be exiting a moving platform. But he's also highly experienced in BASE jumping--that is, making parachute jumps from fixed objects. ("BASE" stands for buildings, antennas, spans/bridges, and earth.) Here, in a multiple-exposure shot from 2004, he leaps into the Marmet Cave in Croatia. At 623 feet deep, it presented much different challenges from what Baumgartner's got before him today.
