On This Day in Space Oct. 14, 1947: Chuck Yeager Breaks the Sound Barrier


I’d like to think this was like it was.

On Oct. 14, 1947, Chuck Yeager broke the sound barrier for the first time! Yeager was a test pilot for the U.S. Air Force who made history by flying an aircraft faster than the speed of sound.

Yeager made his historic flight in a Bell X-1 rocket plane that he named “Glamorous Glennis” after his wife. Yeager had broken two ribs the night before when he fell off a horse, but that didn’t stop him!

His aircraft was dropped from a Boeing B-29 bomber before accelerating to a speed of Mach 1.07, which is about 821 miles per hour. The speed of sound, Mach 1, is about 760 miles per hour.
