This page from Lt. Wayne E. Bancroft's personal flight logbook records his training hours in the PBM-5 Mariner patrol bomber at Naval Air Station Corpus Christi in March 1950. Bancroft would later serve as co-pilot of a PBM patrol bomber lost off the coast of Korea in December 1952. Logbooks like this offer a direct, personal record of the training and experience that prepared naval aviators for wartime service. Project: 218132
