X-14
Mission: The X-14 was designed to explore the feasibility of building a pure-jet vertical takeoff and landing aircraft operating in a conventional (i.e., horizontal) attitude. At one time, it was the longest-lived X-plane program in history. Power was provided initially by two Armstrong-Siddeley Viper 8 axial flow turbojet engines. Later, it was re-engined with General Electric J85 turbojets.
