Peter Girard Peter Frank "Pete" Girard (May 5, 1918 – February 12, 2011) was a United States Army Air Corps pilot, Chief Engineering Test Pilot for Ryan Aeronautical, and the first man to hover in jet vertical flight. This feat was accomplished November 24, 1953 during tests that would culminate in the development of the Ryan X-13 Vertijet. He would later accomplish the first full-cycle vertical takeoff, horizontal flight, and vertical landing in a jet aircraft on April 11, 1957 at Edwards Air Force Base. Prior to working with Ryan, Girard had worked at Curtiss-Wright in St. Louis, Missouri and served in the United States Army Air Corps during World War II as a Consolidated B-24 Liberator pilot.
