The clear skies over southern California was ripped by a small, orange machine, and a sound never heard before issued forth from the cerulean skies... Boom!!!
The Sound Barrier was exceeded.
Congratulations to Chuck Yeager, the first. And just to prove he's still got it, just last month he went Mach 1 in an F-16.
(Tip of the supersonic hat to Phil Plait, who mentioned it at his Bad Astronomy site.)
