This page from Lt. Wayne E. Bancroft's personal flight logbook records his March 1951 flights piloting Martin PBM Mariner patrol flying boats during the Korean War. Naval aviators were required to log every flight in meticulous detail - aircraft type, duration, and role - creating an enduring paper trail of Cold War-era naval aviation. Logbooks such as this offer historians a direct, day-by-day window into the operational tempo of Navy patrol squadrons during the conflict. Project: 218132
