An Air Force Form 5, "Pilots Individual Flight Record," documenting Major Peter D. Williams' flight hours for January 1970. Official flight records like this one tracked every sortie a pilot flew — aircraft type, duration, day/night and instrument conditions, and combat time — and provide a precise, verifiable account of a Vietnam-era Air Force pilot's operational flying career, which by this entry totaled over 4,000 hours, including more than 400 hours of combat flying.
