The Boeing Model 204 was an American biplane, pusher configuration flying-boat aircraft built by Boeing in 1929. Externally the 204 looked identical to the Boeing Model 6E, but a number of internal changes, including increasing the passenger capacity to four, gave it a new Type Certificate and model number.
Construction was started on five aircraft, but only two were completed. The first, designated 204 and the second 204A. A third aircraft was built by a private owner who had bought the three incomplete machines. The 204A was a dual-control version which was later owned by Peter Barnes, who flew it on his private Seattle-Victoria, British Columbia main run.
The C-204 Thunderbird, a modified 204, was the first type produced by Boeing Aircraft of Canada. These had altered wing and tailplane incidence and a reduction in upper wing area. The prototype was first flown on 30 March 1930, the first of a batch of four. They failed to sell readily, though they were sometimes leased for work. Eventually three were sold. All worked in British Columbia, remaining active until 1939.

The Boeing Model 6D, a.k.a. Boeing Model 6E, Boeing B-1D and Boeing B-1E, was an American pusher biplane flying-boat built by Boeing between 1928 and 1929.List of pusher aircraft by configuration
A pusher aircraft is a type of aircraft using propellers placed behind the engines and may be classified according to engine/propeller location and drive as well as the lifting surfaces layout (conventional or 3 surface, canard, joined wing, tailless and rotorcraft),
Some aircraft have a Push-pull configuration with both tractor and pusher engines. The list includes these even if the pusher engine is just added to a conventional layout (engines inside the wings or above the wing for example).
