Contribution to the technique of landing large airships. Part II
A 1929 NACA technical memorandum on landing large airships, issued as a numbered report with technical plates for engineers of the era. Its pictures are black-and-white photographs and engineering drawings of mooring masts, shed frameworks, and airship hulls, with a few handwritten-style captions. A designer might take from them the lattice steel tower forms, the dense truss geometry of hangar sheds, and the streamlined silhouette of rigid airships.
