This page from a Naval aviator's personal flight logbook documents PBM-5 Mariner flying-boat missions flown in December 1950, at the outset of the Korean War. Signed and certified by pilot Wayne E. Bancroft and countersigned by a Lieutenant, USN, the ledger meticulously tracks flight hours, instrument time, and carrier qualifications — a firsthand record of the routine training and patrol duty that underpinned naval aviation operations during the conflict.
