Flying the Bell X-1A, Chuck Yeager becomes the first person to exceed twice the speed of sound.
On the anniversary of Marconi's first transatlantic radio signal, the U.S. military launched the first privately built satellite into orbit around the Earth. OSCAR1 - short for Orbiting Satellite Carrying Amateur Radio - hitched a ride aboard a Discoverer satellite that was launched into orbit by a U.S. military Thor-Agena rocket. The payload orbited the Earth for 22 days sending the message "Hi" by Morse code to approximately 300,000 amateur radio operators tracking OSCAR1.
