                         Messerschmitt Me 163B Komet

The Messerschmitt Me 163 Komet was a German rocket-powered interceptor 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 performance and aspects of its design were unprecedented. German test pilot Heini Dittmar in early July 1944 reached 1,130 km/h (700 mph), an unofficial flight airspeed recordunmatched by turbojet-powered aircraft for almost a decade. Over 300 Komets were built, but the aircraft proved ineffective in its dedicated role as an interceptor and destroyed about nine to 18 Allied aircraft against 10 losses.Aside from combat losses many pilots were killed during testing and training.

Me 163B-1a

Werknummer 191659 and RAF Air Ministry serial number AM215, “Yellow 15”, was captured at Husum in 1945 and was sent to the College of Aeronautics at Cranfield, England in 1947. After many years of touring airshows and various outdoor gatherings around the UK it was loaned to the National Museum of Flight at East Fortune Airfield, East Lothian, Scotland in 1976.
