It was in 1912 that AEG began to produce aeroplanes on the former Teltow aerodrome near Berlin. In 1913, AEG used metal construction fort he first time in Germany. Aeroplanes were built using seamless drawn tubing that was welded for the fuselage frame. Later, even wing spars were built with this technology. Another pioneer work of the AEG aircraft construction was the introduction of hinged wings. During WW I the factory was relocated to Berlin-Henningsdorf, where a runway with a length of 3 km was established. The factory then was shifted to Johannisthal at the end of the war. Some large bombers became well-known as war planes, e. g. the AEG G.IV. In 1919, AEG was forced to discontinue aircraft construction based on an order by the Western Allies. The major part of the personnel was taken over by the locomotive department being part of the factory. Aircraft construction did not resume until 1933, when an electrical helicopter was developed. Apart from this development work taking place in Berlin, AEG had a high-capacity plant in Wildau near Königswusterhausen. Among other things, empennages for Ju-88, 188, and 388 were produced and repaired in this plant.
