Additional Information: The X-14 was the X-Plane with possibly
the longest research flight life. It is also the only open cockpit X-Plane.
Beginning tethered flights in February of 1957, the single X-14 constructed
was not retired until late in 1981, due to damage from a hard landing. During
these years, there were no serious incidents or injuries incurred from flying
the X-14. Over 25 pilots flew the X-14 as their first VTOL experience in
preparation for flying more advance VTOL craft.
The X-14 is now on display at the US
Army Aviation Museum at Ft. Rucker Alabama.
