Due to restrictions after World War I the Heinkel He 111 was disguised as an airliner, and flew with Lufthansa starting in 1934.1,4 It however, could be converted into a bomber.1
The pilot sat on the left, and the bombardier on the right in the cabin.1 There was a gangway that went between the bomb racks back to the rear compartment that held the gunners and radio operator.1
There was a ventral gondola that had a MG in it.1 However, it was called the Sterbebett (Deathbed) as it was very vulnerable to attacks from below.1
The allies soon learned to attack from the front of the He 111 as there was no armor in front.1
The early models had the more normal stepped cockpits.3
The broad dihedral wings gave excellent stability and the ability for the He 111 to carry heavy loads.1
The fuselage and tail section was made from metal, including the skin.1 The allowed for great durability, and sometimes could even fly with a destroyed elevator.1
Rockets could be fitted to help the He 111 take off from short or rough fields or with heavy loads.1

The He 111 first flew at Marienehe on February 24, 1934.1,2,3
The He 111H prototype first flew in January 1938.3
The He 111V8 (became the He 111P) prototype first flew in January 1938.3
Over 7,300 He 111s were produced.1,2

Models used by which countries:
The He 111s were extensively used in the early German campaigns.3
There were over 400 He 111Hs in service by September 1939.3,4
The Condor Legion was supplied with the He 111 in the Spanish Civil War.1 They received 30 He 111B-1s in February 1937.2,3
The He 111s proved to be vulnerable to the Hurricanes and Spitfires of the Royal Air Force (RAF).4
