Messerschmitt Me 163

The Messerschmitt Me 163 Komet was a rocket-powered interceptor fighter produced in the 1940s, the only operational aircraft to adopt this propulsion system during the Second World War. It achieved unrivalled performance for its time, reaching 1,123 km/h in 1944. T-Stoff was so corrosive that, in the event of a crash, it could literally dissolve the pilot's body. Source: Wikipedia
