While Felix Baumgartner was getting ready to jump out of his capsule at an altitude of 39 km to begin his supersonic skydive, something else supersonic was taking place elsewhere: The man who first broke the sound barrier, Chuck Yeager, flew faster than sound again in the back seat of an F-15 Eagle. Way to go, General Yeager! I hope I will be at least half as healthy as you are when I turn 89.
