Speed and Deceleration Trials of U.S.S. Los Angeles
A 1930 NASA technical report on speed and deceleration trials of the U.S. Navy airship U.S.S. Los Angeles, compiled for engineers and airship researchers. Its pictures are graph plots of time against reciprocal speed with fitted mean-slope lines, plus one photograph of the airship's underside on a field with ground crew. A designer might take from them the clean, sparse plotting style of early engineering charts and the stark rigid-airship silhouette.
