A page from a U.S. Navy cadet's personal flight logbook, June 1943, recording a 3.3-hour training flight in a North American SNJ-4 advanced trainer at the Naval Air Training Center, Corpus Christi, Texas. The adjoining monthly summary, certified by the pilot and countersigned by the base Operations Officer, shows a cumulative total of 214.1 flight hours — a record of the intensive training pipeline that prepared thousands of naval aviators for combat during the Second World War.
