LWC-05 Heinkel He-70

Luftwaffe Cargo Supply - The Heinkel He 70 Blitz ("lightning") was a fast monoplane aircraft designed and produced by the German aircraft manufacturer Heinkel Flugzeugwerke. It was the first Schnellbomber operated by the Luftwaffe. Development of the He 70 commenced in the early 1930s in response to a request from Deutsche Lufthansa for a fast mail plane. Heinkel designed a low-wing cantilever monoplane that incorporated various measures to minimise drag, including its use of an aerodynamically efficient elliptical wing, a smooth external finish, and a retractable undercarriage. The He 70 was powered by a single nose-mounted BMW VI 7.3 Z engine and cooled via a relatively compact retractable radiator as a further drag-reducing measure. The first prototype performed its maiden flight on 1 December 1932 and set eight separate world speed records over the following months.
