File talk:Keystone B-6 twin-engine airmail plane in snow storm, 1920.jpg

Misidentification

I have amended the description and categories of this image to reflect that it portrays a Keystone B-6 aircraft in 1934, not the "De Havilland" in "1920" described by the National Postal Museum, the source of the image. First, the image shows a very large twin-engined biplane with radial engines; De Havilland produced a similar-looking aircraft, the DH.66, but it had three engines, and no examples are recorded as being used in the US. Reference to the cited source shows that the postal service briefly used the DH.4B, an experimental twin-engined conversion of the small DH.4 being employed on US air mail services in the 1920s. It appears that the National Postal Museum erroneously connected that episode with the image here. The cited source shows that in the very extreme weather conditions in early 1934, Keystone B-6s of the US Army Air Corps briefly replaced commercial air mail contracts, until a major political scandal (see en:wp article Air Mail scandal). See various accounts and images on the source website. In my rationale, no other aircraft type matches the image.PeterWD (talk) 09:08, 1 December 2011 (UTC)
