Why: Air Force pilot Chuck Yeager flew the X-1 to Mach 1.06 at 43,000 feet. The X-1 was carried up under a B-29 bomber and dropped before lighting its rocket.

Huh, didn't know that: The flight was so important that the Air Force made it Top Secret two hours later.

Why did Chuck Yeager fly so fast? He heard there was a sound barrier and wanted to beat it to the punch.
