A technician makes adjustments to a scale model of the XB-70 Valkyrie before aerodynamic characteristics related to the aircraft are evaluated in Tunnel A of the von Kármán Gas Dynamics Facility at Arnold Air Force Base, Tenn., headquarters of Arnold Engineering Development Complex, in 1959. Beginning in the late 1950s and continuing through the mid-1960s, tests were conducted at Arnold Air Force Base, Tenn., headquarters of Arnold Engineering Development Complex, in support of the XB-70 program. Only two Valkyries were built, with only one of the pair remaining. The now-retired aircraft made its first flight on Sept. 21, 1964. (U.S. Air Force photo)
