The Walter HWK 109-509 powered the first piloted aircraft of any type to exceed how many MPH in level flight?
Messerschmitt Me 163 Komet The Messerschmitt Me 163 Komet was a German rocket-powered fighter aircraft. Designed by Alexander Lippisch, it is the only rocket-powered fighter aircraft ever to have been operational and the first piloted aircraft of any type to exceed 1000 km/h (621 mph) in level flight. Its design was revolutionary and its performance unprecedented. German test pilot Heini Dittmar in early July 1944 reached 1130 km/h , an unofficial flight airspeed record unmatched by turbojet-powered aircraft for almost a decade. Over 300 aircraft were built, but the Komet proved ineffective in its dedicated role as an interceptor aircraft and was responsible for the destruction of only about nine to eighteen Allied aircraft against ten losses. Aside from combat losses many pilots were killed during testing and training.
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.
