This 1954 photo shows the prototype Republic YRF-84F Thunderstreak on the ramp adjacent to Hangar 4802 at the NACA High-Speed Flight Research Station. The one-of-a-kind prototype, Air Force serial number 51-1828, NACA tail number 154, was flown from 1954 through 1956 to gather research data on the pitch-up phenomenon, a common problem with early swept-wing aircraft.1954NACA/NASA photo› RF-84F Project Description
