Dated 15 September 1971, this page from a USAF fighter aircrew manual outlines the emergency air refueling procedure: how a pilot separated from formation or critically low on fuel would contact Ground Controlled Intercept and relay call sign, fuel state, position, altitude, and ordnance load to arrange a tanker rendezvous. Procedures like this were vital lifelines for F-4 Phantom crews flying long-range missions over Vietnam and Laos, where running low on fuel far from base could quickly become a life-or-death situation.
