A page from a U.S. Navy fighter pilot's personal flight log book, recording flights flown in October 1943. The entries trace a young aviator's progression through fleet training -- familiarization hops, sector tactics, oxygen equipment checks, dummy and live gunnery runs, and night flying -- in the Grumman F4F Wildcat, its General Motors-built FM-1 variant, and the SNJ advanced trainer. Log books like this one document, flight by flight, the rigorous preparation required before a Navy aviator was ready for carrier squadron duty in the Pacific War. Project: 218060
