This photograph, purporting to depict the first prototype Heinkel He 178, this appears more likely to be a picture of a mock-up of a possible third aircraft. Many features appear common to the second prototype, but this machine has a longer canopy and enlarged fin and rudder.
Another view of the Heinkel He 178 V2. It was powered by the He S6 engine, designed to produce 1,200lb-thrust at 13,000 r.p.m.
A front view of the Heinkel He 178 V2, the second prototype. It had a fully retractable undercarriage and wider-span wings than the first prototype, but was never flown.

Another view of the He 178 V2, showing the straight tapered wings - the first prototype had elliptical trailing edges.
Первый взлет He 280V2. 30 марта 1941г.
The Heinkel He 280 prototype takes off from the Heinkel factory airfield at Rostock-Marienehe on its first flight under power, on April 2, 1941 (some sources give the date as March 30). The first 40 or so flights were made as a glider, towed behind a Heinkel He 111H. The He 280’s engine cowlings were removed for the first flight as a precaution against fire, as unburnt fuel had collected in them during ground-running trials.
