This U.S. Air Force AFTO Form 5 flight record documents the combat flying hours of 1Lt Donald L. Engebretsen in the A-1H Skyraider during late 1969. Such official flight-time ledgers, meticulously recorded to the tenth of an hour, provide historians a precise account of a Vietnam-era attack pilot's sortie tempo, day/night and instrument proficiency, and cumulative combat exposure.
