From Wikipedia, the free encyclopedia
The Hiller X-18, also known as the "Propelloplane",[1] was an experimental aircraft built by the Hiller Aircraft Corporation for the United States Air Force. Intended as a testbed for tiltwing technology in the development of practical V/STOL aircraft. Proving troublesome in testing, a near accident resulted in the grounding of the aircraft, and only limited further testing was performed before the program was cancelled.
