On This Day in Space: April 22, 2010: X-37B space plane launches on 1st top-secret mission
On April 22, 2010, the U.S. Air Force launched the super-secret X-37B space plane on its first spaceflight.
On July 17, 1962, American test pilot Bob White broke the world record for the highest flight.
On July 17, 1962, the American test pilot Bob White broke the world record for the highest altitude flight.
He took off from Edwards Air Force Base in a rocket-powered X-15 aircraft and made it to an altitude of 314,750 feet. That's almost 60 miles!

At the time, the Air Force considered the edge of space to be 50 miles above the Earth. So White received astronaut wings for his record-breaking spaceflight.
