50th Anniversary of XC-142A First Conventional Flight and First Transitional Flight

     Born in a Joint Services requirement for a V/STOL transport. A winning bid was submitted by a combined  Vought-Hiller-Ryan team with Vought being the prime contractor. the VHR-447 design which became the XC-142A. The award was for five aircraft serial numbers 62-5921 to 62-5925.

The XC-142A first flew on Sept. 29, 1964. The flight was accomplished with conventional take-off and landing. On Jan. 11, 1965 the XC-142A completed its first transitional flight taking off vertically, transitioning to conventional flight and returning to land vertically.

The XC-142A aircraft were extensively tested by the military services. At one time three of the five aircraft were participating in testing in California at the same time. There is a video link at the end of this post that leads to a digitized film of the XC-142 testing.

During it's time it was the largest and fastest V/STOL aircraft. Capable of a 400 mph forward speed and a reverse speed of 35 mph. Unfortunately technical problems, accidents and changing needs spelled the end of the program. Of the five XC-142As built, only one aircraft survives today. 62-5924 went on to serve with NASA as NASA 522 and is currently on display in the National Museum of the US Air Force.
