	X-5 Program Flight Chronology 1952-1955 The NACA High-Speed Flight Station operated the Bell X-5 #1 (50-1838) from 1952 to late 1955. Following the conclusion of the contractors program in October 1951, the airplane was grounded for installation of a NACA instrument package. In December 1951, the Air Force completed a brief evaluation program involving six flights; because data were taken, these were considered part of the overall NACA effort and were logged as join AF-NACA flights. The first all-NACA flight was flight 7, and it is with this flight that this chronology begins. The second X-5 (50-1839) was operated only by Bell and the Air Force and was lost in a spin accident in 1953. Bell X-5 #1 (50-1838) Flights
