The "Turkey Buzzard" glider
A 1923 technical report on the Turkey Buzzard glider, published by NASA's Technical Reports Server from an earlier archived record, and aimed at engineers and builders rather than general readers. The pictures are black-and-white engineering drawings: a wing rib and spar layout with bracing wires, a plan and side elevation with numbered stations, a gliding-angle graph plotted against speed, and a small detail of a wooden frame joint with dimensions. A designer could take their clean line-drawing style, dimension callouts and labelled schematic diagrams as models for technical illustration.
