DEFENDERS OF AMERICA from National Biscuit Company: X-15 ROCKET POWERED RESEARCH PLANE


Before you read about the X-15 I wanted to let you know you can see several vintage snapshots my father took of seaplanes in the late 1940s and early 50s by visiting my other site, Tattered and Lost Photographs.

And now...the X-15, courtesy of the National Biscuit Company late 1950s trading cards.

The North American X-15 was a rocket-powered aircraft operated by the United States Air Force and the National Aeronautics and Space Administration (NASA) as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the early 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. As of 2012, the X-15 holds the official world record for the fastest speed ever reached by a manned rocket-powered aircraft.
During the X-15 program, 13 different flights by eight pilots met the USAF spaceflight criteria by exceeding the altitude of 50 miles (80 km) thus qualifying the pilots for astronaut status. The USAF pilots qualified for USAF astronaut wings, while the civilian pilots were awarded NASA astronaut wings in 2005, 35 years after the last X-15 flight.
Of all the X-15 missions, two flights (by the same pilot) qualified as space flights per the international (Fédération Aéronautique Internationale) definition of a spaceflight by exceeding 100 kilometers (62.1 mi, 328,084 ft) in altitude.
