Two-seat closed cockpit parasol-winged observation monoplane, the only survivor of 90 built for the USAAC from 1935. Crashed at Harlingen TX 27.11.42 and remains retrieved in 1967 and restored for display.
The US Navy's AJ Savage was a carrier-capable nuclear bomber. It was powered by two R-2800 radials plus an auxiliary jet engine with a retractable dorsal intake. NASA used three Savages for weightlessness (zero gravity) simulation, including this one, Navy serial 134069. Photo from: NASA
The X-13 was intended to prove that a jet could take off vertically, transition to horizontal flight and return to vertical flight for landing. It was hoped that such a jet would lead the way for submarine-based aircraft and provide offensive capability should conventional runways be destroyed in an attack. This is the second of two X-13s, completing the first full-cycle flight in April 1957 at Edwards AFB and is now on dispaly in the R&D Gallery of the NMUSAF's new fourth building.
