Feather Drop ` - Dec 1, 2012
Felix Baumgartner was nearly in free fall as he stepped out of his capsule at an altitude of 39 kilometers (24 miles). At this altitude, the atmosphere is so thin that a falling object experiences hardly any air resistance, so it accelerates rapidly to very high speed (Baumgartner's skydive exceeded the speed of sound).
