This silent reel of film shows various V/STOL and VTOL test aircraft, and originated at the NASA Langley Research Center.The film begins with footage of the V/STOL X-100, tail #N853, in a transition attempt at :34. In March 1960 the Curtiss-Wright Corporation developed the X-100, a prototype for a new, vertical takeoff transport aircraft. The X-100 had a single turboshaft engine, which propelled two tilting-propellers, while at the tail swivelling nozzles used the engine’s exhaust gases to give additional control for hovering or slow flight. Although sometimes classified as a tiltrotor aircraft, the design differed from the Bell VTOL XV tiltrotor designs. The X-19 utilized specially designed radial lift propellers, rather than helicopter like rotors, for vertical takeoff and augmenting the lift provided by the wing structures.

From the X-100 Curtiss-Wright developed the larger X-200, of which the United States Air Force ordered two prototypes designated the X-19A. At 3:17 the McDonnell XV-1 is shown. This was an experimental compound gyroplane developed for a joint research program between the United States Air Force and the United States Army to explore technologies to develop an aircraft that could take off and land like a helicopter but fly at faster airspeeds, similar to a conventional airplane. The XV-1 would reach a speed of 200 mph (320 km/h; 170 kn), faster than any previous rotorcraft, but the program was terminated due to the tip-jet noise and complexity of the technology which gave only a modest gain in performance. At 5:03 the Ryan VZ-3 is shown. The VZ-3 was a simple proof-of-concept experimental aircraft using blown flaps to achieve a short or near vertical take-off. It was a high-wing monoplane powered by an Avco Lycoming T53 turboshaft engine located inside the fuselage driving two large-diameter propellers mounted, one on each wing. It had a T-tail and originally a tailwheel fixed landing gear. It had wide-span double retractable trailing-edge flaps, these were extended into the propeller slipstream for takeoff. To enable control while in the hover it had a universally-jointed jet-deflection nozzle at the rear of the aircraft. The VZ-3 could make a near-vertical takeoff within 30 ft (9m) at a speed of 25 mph (40 km/h) and the aircraft could be put into the hover up to a height of 3,700 ft (1,100 m). At 9:49 the Curtiss-Wright X-19 is shown. This was a successor to the X-100. The X-19 utilized specially designed radial lift propellers for vertical takeoff and augmenting the lift provided by the wing structures. From the X-100 Curtiss-Wright developed the larger X-200, of which the United States Air Force ordered two prototypes designated the X-19A. At 16:37 the XC-142A is shown. The Ling-Temco-Vought (LTV) XC-142 was a tri-service tiltwing experimental aircraft designed to investigate the operational suitability of vertical/short takeoff and landing (V/STOL) transports. An XC-142A first flew conventionally on 29 September 1964, and on 11 January 1965, it completed its first transitional flight by taking off vertically, changing to forward flight and finally landing vertically. Its service sponsors pulled out of the program one by one, and it eventually ended due to a lack of interest after demonstrating its capabilities successfully. At 20:00 the Bell X-22A is shown. Bell X-22 was an American V/STOL X-plane with four tilting ducted fans. Takeoff was to selectively occur either with the propellers tilted vertically upwards, or on a short runway with the nacelles tilted forward at approximately 45°. Additionally, the X-22 was to provide more insight into the tactical application of vertical takeoff troop transporters such as the preceding Hiller X-18 and the X-22 successor, the Bell XV-15. Another program requirement was a true airspeed in level flight of at least 525 km/h (326 mph; 283 knots). At 23:33 the Turbojet Ryan X-13 Vertijet is shown. Ryan X-13 Vertijet (company designation Model 69) was an experimental vertical take-off and landing (VTOL) jet aircraft flown in the United States in the 1950s. The main objective of the project was to demonstrate the ability of a pure jet to vertically takeoff, hover, transition to horizontal forward flight, and vertically land. The Bell X-14 is shown at 25:40. Bell X-14 (Bell Type 68) is an experimental VTOL aircraft flown in the United States in the 1950s. The main objective of the project was to demonstrate vectored thrust horizontal and vertical takeoff, hover, transition to forward flight, and vertical landing. At 29:46 the Kestrel Squadron patch for Harrier pilots is shown. A Harrier is shown at 30:00 taking off and doing fly-bys.
