Selected images of the newly rebuilt Cologne airport, originally published in Moderne Bauformen - Monatshefte für Architektur und Raumkunst [Modern Construction Design - Monthly Magazine For Architecture And Interior Art], volume XXXVI, issue no. 6, June 1937, Julius Hoffmann Verlag, Stuttgart, Germany.
Top: parked aircraft inside the grosse Flugzeughalle [large aircraft hangar]. The aircraft in the centre is De Havilland D.H.86A (later D.H.86B), G-ADUG, operated by Imperial Airways.
The hangar was surrounded on the outside by an extension along three of its walls. This extension housed a variety of rooms used by Deutsche Lufthansa, such as workshops and storage facilities. Further rooms were used by the air traffic control.
Centre and bottom: enlargements of the main photo, showing Focke-Wulf A 47 D, D-IJTE, and, partially hidden behind a Lufthansa Heinkel He 70 and the Imperial Airways D.H.86 G-ADUG, an unidentified Junkers Ju 86.
