Through development it was described as a "wolf in sheep's clothing" because the project masqueraded the machine as civilian transport, though from conception the Heinkel was intended to provide the nascent Luftwaffe with a fast medium bomber.
Dornier Do K The Dornier Do K was a German commercial passenger and freight monoplane, designed by Claude Dornier and built by Dornier Flugzeugwerke. Only three prototypes of different designs were built and the type was not a commercial success.
