The Flaming Coffin

• The Army Air Service was called upon to supply
  the Army Corps of Engineers and the Geological
  Survey with aerial photos for mapping and stereo
  viewing. The DH-4 was the most suitable and,
  because of its great numbers, the most available
  plane for the job. It was used as the standard
  airplane for the purpose for 10 years.Other uses
  of the plane
• It was called the flaming coffin because if the
  plane got shot at it caught on fire it would burn
  down like a bird on fire and crash.

After the War

• With few funds to buy new aircraft in the years
  following World War I, the US Army Air Service
  used the DH-4 in a variety of roles, such as
  transport, air ambulance, photographic plane,
  trainer, target tug, forest fire patroller and
  even as an air racer. In addition, the US Post
  Office operated the DH-4 as a mail carrier.
• The DH-4 also served as a flying test bed at
  McCook Field in the 1920s, testing turbo
  superchargers, propellers, landing lights,
  engines, radiators, and armament. There were a
  number of notable DH-4 flights such as the
  astounding New York to Nome, Alaska flight in
  1920, the record breaking transcontinental flight
  in 1922 by Jimmy Dolittle and the first
  successful air-to-air refueling in 1923.

• 1,538 DH-4s were modified in 1919-1923 to DH-4Bs
  by moving the pilot's seat back and the now
  unpressized gas tank forward, correcting the most
  serious problems in the DH-4 design. A further
  improved version was the DH-4M whereby over 300
  DH-4s received new steel tube fuselages.
• By the time it was finally retired from service
  in 1932, the DH-4 had developed into over 60
  variants.
