The Heinkel He 70 was a German mail plane, passenger, liaison, training and bomber aircraft of the 1930s. Although useful, it had a relatively brief commercial career before it was replaced by types which could carry more passengers. As a combat aircraft, it was a not a great success because it rapidly became outdated. Nevertheless, the He 70 was a brilliant design for its day, setting no fewer than eight world speed records by the beginning of 1933.
The Heinkel He 70 Blitz was designed in the early 1930s to serve as a fast mailplane for Deutsche Lufthansa. The He 70 was developed in response to Lufthansa request for a faster aircraft than the Lockheed Vega and Orion (as used by Swissair) for employment on short routes. It was a low-wing monoplane, with the main characteristics of its revolutionary design its elliptical wing, which the Günther brothers had already used in the Bäumer Sausewind sports plane before they joined Heinkel, and its small, rounded control surfaces. In order to meet the demanding speed requirements, the design minimised drag, with countersunk rivets giving a smooth surface finish and a retractable undercarriage, a novel feature for a German aircraft. It was powered by a BMW VI V-12 engine, cooled by ethylene glycol rather than water, allowing a smaller radiator and therefore reducing drag. The pilot and radio operator were seated in tandem, with a cabin housing four passengers on two double seats facing each other.
The first prototype flew on 1 December 1932, and proved to have excellent performance, setting eight world records for speed over distance, and reaching a maximum speed of 377 km/h (222 mph).
Lufthansa operated He 70s between 1934 and 1937 for fast flight service which connected Berlin with Frankfurt, Hamburg and Cologne, as well as the Cologne/Hamburg route. Lufthansa He 70s were flown abroad from Stuttgart to Sevilla between 1934 and 1936. Remaining aircraft were transferred to the Luftwaffe in 1937.
Twenty-eight aircraft were sent with the Legion Kondor, where they were used during the Spanish Civil War as fast reconnaissance aircraft. Their high speed gave them the nickname Rayo (lightning), ("blitz" in german).
