This pink reference card, dated December 1971, provided F-4 Phantom II aircrews of the 57th Fighter Weapons Wing with standardized procedures for handling in-flight emergencies and for supporting rescue combat air patrol (RESCAP) operations to locate downed airmen. Carried in a pilot's kneeboard binder, such cards were essential quick-reference tools during training and combat operations at bases like Nellis Air Force Base, Nevada, reflecting the rigorous procedural discipline of Vietnam-era fighter aviation.
