Photograph of airmail planes at Omaha, Nebraska
The Post Office Department constructed hangars for their use at this Omaha, Nebraska airmail field. Omaha was part of the transcontinental flyway between New York City, New York to San Francisco, California. A group of mail airplanes are parked in front of the main hangar. Most of the craft are de Havilland DH-4B airplanes, an airplane that was nicknamed the workhorse of the early airmail service. A Boeing B40 aircraft is parked at the far right of the photograph. Two Douglas M2 aircraft are parked next to each other at the far left of the photograph. These airplanes were among those built as part of a search by postal officials for a successor to the de Havilland. Few B40s or M2s were used for airmail service under the Department, but both airplanes were used in the late 1920s by commercial aviation companies.
