| Bell X-5 during test flight over Edwards AFB This NACA High-Speed Flight Research Station photograph of the X-5 was taken at Edwards Air Force Base in the mid 1950s. The photograph shows the aircraft in flight with the wings swept back, 1957. The Bell, X-5 was flight tested at the NACA High-Speed Flight Research Station (now the NASA Dryden Flight Research Center, Edwards, California) from 1952 to 1955. The X-5 was the first aircraft capable of sweeping its wings in flight. It helped provide data about wing-sweep at angles of up to 60 degrees at subsonic and transonic speeds. |

The photograph portrays a left wing side view of the aircraft and also shows the pitot-static probe, used to measure airspeed, Mach number, and altitude, mounted on a noseboom protruding from the top of the aircraft's nose engine inlet. Also attached to the static probe portion of the noseboom are flow direction vanes for sensing the aircraft’s angles-of-attack and sideslip in flight. |

| Bell X-5 on ramp at Edwards Air Force Base This NACA High-Speed Flight Research Station photograph of the X-5 was taken at the South Base of Edwards Air Force Base in 1952. The photograph is a left side view of the aircraft on the ramp. The X-5 was the first aircraft capable of sweeping its wings in flight. It helped provide data about wing-sweep at angles of up to 60 degrees at subsonic and transonic speeds. |

| Bell X-5 in front of NACA hangar, Edwards AFB The X-5 was the first aircraft capable of sweeping its wings in flight. It helped provide data about wing-sweep at angles of up to 60 degrees at subsonic and transonic speeds. This NACA High-Speed Flight Research Station photograph of the X-5 was taken at the South Base of Edwards Air Force Base. |

| Bell X-5 with wings extended out for low speed The Bell X-5 was taken at the South Base of Edwards Air Force Base. The photograph shows a frontal view of the X-5 on the ramp in-front of the NACA hangar. This view also provides a good view of the pitot-static probe, used to measure airspeed, Mach number, and altitude, mounted on a nose boom protruding from the top of the aircraft's nose engine inlet, 1952. |

| Bell X-5 with wings in high speed position Bell X-5 was taken at the South Base of Edwards Air Force Base. The photograph, on the ramp in-front of the NACA hangar, shows a frontal view of the X-5 illustrating it's wing sweep capability. This view also provides a good view of the inlet and attached nose boom on the top. |

| Bell X-5 variably swept wing capability This NACA High-Speed Flight Research Station photograph of the X-5 was taken at the South Base of Edwards Air Force Base. The photograph, a multiple exposure, illustrates the X-5's variably swept wing capability. |
