OTD In Space – August 22: X-15 Sets World Altitude Record
- 8 months ago
On Aug. 22, 1963, U.S. Air Force Captain Joe Walker flew an X-15 space plane higher than any pilot had ever flown before.
Walker reached an altitude of over 67 miles (108 kilometers). That's about 5 miles (8 km) above the edge of space! Walker experienced about five minutes of weightlessness over the course of the 11-minute flight. This was the second and final suborbital spaceflight of the X-15 program. Walker piloted both flights and became the first person to go to space twice. For both flights, he flew in the space plane X-15 #3, which also became the first reused spacecraft to return to space.
