Wolf 20, Cherry has a tally. Check nose is cold . The leader may tell the boomer what the refueling order is. Wolf, refueling order is 2,4,3,1. The tanker has lights on the bottom of its fuselage that cue the pilot into position.
Most people try to keep it quiet.
As must be obvious, air refueling is a most demanding process. Everyone is at max attention since the slightest error can spell disaster. The general idea is for the F-4 pilot to stabilize in a position below and slightly behind the tanker. Once stabilized in position, the boomer will fly the boom to the refueling receptacle on the back of the F-4 to the rear of the aft canopy. The boomer then plugs the boom into the F-4 and begins to pump gas.
