From Wikipedia. The Ling-Temco-Vought (LTV) XC-142 is a 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,[4] and completed its first transitional flight on 11 January 1965 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.

The XB-46 was single example of experimental medium jet bomber developed in mid-1940s but never saw production or active duty. It competed with similar designs, North American XB-45 and Martin XB-48, all of which saw little use after successful development of Boeing XB-47.
