Waycross celebrated the arrival of brand new P-51 Mustangs in April, 1945. Initially, Waycross operated an equal number of P-40s and P-51s. The only problem encountered with the Mustang was cockpit heat caused by the aircraft's bubble canopy during summer. As a result, the RTU operated the Mustangs above 5,000 ft. using them mainly for air-to-air gunnery. In May, Waycross received one Douglas C-47 and one Beech C-45. The C-47 took the base's enlisted men on cross-country liberty flights while the officers had use of the C-45. Liberty flights were flown to Washington, D.C., New York City, Chicago, Pittsburg, and St. Louis and other cities.
