The Latecoere 501 commercial seaplane (French) : a three-engine metal sesquiplane
This 1932 NACA aircraft circular from NASA's Technical Reports Server documents the Latecoere 501, a French three-engine metal sesquiplane flying boat, with photographs and drawings for aeronautical engineers. Its pictures show exterior views of the seaplane on water, interior cabin and hull views, a line drawing of the wing and engine layout, and a cockpit instrument panel, useful to a designer seeking vintage aviation or technical drawing references.
