Ling-Temco-Vought XC-142

The Ling-Temco-Vought (LTV) XC-142 was a tri-service tiltwing experimental aircraft designed to investigate the operational suitability of vertical/short take-off 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.

Five aircraft were built, only one still survives.

XC-142A is on display in the experimental aircraft hangar at the National Museum of the United States Air Force at Wright-Patterson Air Force Base near Dayton, Ohio.
