Dated 15 July 1971, this page lists ten specific responsibilities for the crew of a radio-out fighter aircraft, from monitoring emergency channels and squawking the proper identification code to reducing aircraft weight and watching for light signals from the control tower. These procedures reflect the layered contingency planning built into every F-4 Phantom combat sortie flown from Da Nang Air Base during the Vietnam War, ensuring a communications failure never left a pilot without a plan.
