My congratulations to SunvsorFlyer who nailed the quiz! No bonus points however.
The US Army awarded a contract to Ryan to develop and design a V/TOL jet-powered aircraft in the 1960s for battlefield surveillance. One objective was to prove the "fan-in-wing" VTOL concept. The subsequent Ryan VZ-11RY of 1961 was redesignated to XV-5 in 1962. The XV-5 Vertifan used LIFT-FANS in each delta WING driven by the powered gas thrust of two turbojet engines, and a smaller LIFT-FAN was in the aircraft's nose. Louvered vanes deflected lift below the wings for vectored thrust fore & aft also for yaw control. In conventional flight hinged-covers were shut in the wings' upper airfoil. The smaller nose fan was for pitch control. Turbojet engines' power determined the rpm of the fans. Roll control was by differential vane thrust actuation in the two wings. Aircraft was sub-sonic in forward flight.
My answers:
1a. Ryan Aeronautical Company. 1b. XV-5 VERTIFAN. 1c. Turbojets-two General Electric J85-GE-5s of 2,650 lbft thrust each.
2. US Army Aviation, Fort Rucker, Alabama.
3a. May 25, 1964. 3b. First VTOL, hover & vertical landing flight July 1964. (First transition flight, not asked, was November 5, 1965).
4. 338 flights were made by the Army's test program until March 1967. The surviving VX-5 that same month was provided to NASA at Ames Research Center who modified the tri-gear's main gear to be outboard of the wing lift-fans rather than inboard of them, for better ground stability and braking. This denoted VX-5B version. NASA continued V/STOL testing until 1974.
5. Army Aviation Museum, Fort Rucker, Alabama.
6. Bonus. The original basic "fan-in-wing" thrust concept VTOL aircraft was the AVRO VZ-9 of 1959.

As an aside, I made two trips to Fort Rucker on business in the mid-late 1970s when in Flight Test Division of the Pacific Missile Test Center and did a side-tour of their aviation museum then. Great Southern hospitality
