U.S.N.T.S. Aircraft Recognition Card: A-30 Baltimore Medium Bomber (Form 2, Columbus, Ohio, 12-8-42)
A page from a 1942 U.S. Navy Training School aircraft recognition manual identifying the Martin A-30 Baltimore, a twin-engine medium bomber used by U.S. Army and RAF forces. Photographs and silhouette diagrams trained wartime observers and aircrew to instantly distinguish friendly and enemy aircraft by shape, a vital skill before radar identification became widespread.
