X-15 Flight 90 pilot, Joe Walker

Flight 90 of the North American X-15 was a test flight conducted by NASA and the US Air Force in 1963. It was the first of two X-15 missions that reached space, along with Flight 91 the next month. The X-15 was flown by Joseph A. Walker, who flew both X-15 spaceflights.

Mission parameters

  • Mass: 15,195 kg fueled; 6,577 kg burnout; 6,260 kg landed
  • Maximum Altitude: 106.01 km

  • Launch Vehicle: NB-52B Bomber #008

Mission highlights

Maximum Speed - 5,971 km/h. Maximum Altitude - 106,010 m. 80 cm diameter balloon towed on 30 m line to measure air density. First X-15 flight over 100 km (a height known as the Kármán line). This made Walker the first US civilian in space.[1] This was also the first spaceflight of a spaceplane in aviation history. First flight launched over Smith Dry Lake, NV. Experiments: Towed balloon, horizon scanner, photometer, infrared and ultraviolet. Balloon instrumentation failed.

The mission was flown by X-15 #3, serial 56-6672 on its 21st flight.

Launched by: NB-52B #008, Pilots Fulton & Bement. Takeoff: 17:19. UTC Landing: 19:04 UTC.

Chase pilots: Crews, Dana, Rogers, Daniel and Wood.

The X-15 engine burned about 85 seconds. Near the end of the burn, acceleration built up to about 4g (39 m/s²). Weightlessness lasted for 3 to 5 minutes. Re-entry heating warmed the exterior of the X-15 to 650 °C in places. During pull up after re-entry, the acceleration built up to 5g (49 m/s²) for 20 seconds. The entire flight lasted about 12 minutes from launch to landing.
