Prospective development of giant airplanes
A 1928 technical report on proposed giant airplanes, issued through the NASA Technical Reports Server from an earlier aeronautical document. The pictures are black-and-white engineering drawings: plan and elevation views of a very large multi-engined flying wing with passenger cabins and dimension lines in metres and feet. A designer could take from them the clean line-drawn technical diagram style, with numbered callouts and labelled dimensions.
