A point about 1/3 down the runway (touchdown aiming point) from which one would begin a 360 degree descending circle and land. It was basically a 360 degree overhead pattern started at an altitude (F-105 was 12,000 AGL) that would permit 250 KCAS to be carried throughout the circle. You dropped the gear at high key or held it until you made the profile (usually if you did not have the high key altitude to begin with). You played the diameter of the circle to give you 6,000 ft at the 180 degree point and 3000 at the 270 point.Flaps came down when you had the runway made. Speed brakes were as necessary. Ram air turbine was put by the pilot when the engine quit. It ran one of the two flight control systems - barely. One guy had big engine problems and did a bonafide SFO at Norvenich AB, Germany, near Cologne, and when he put the ram air turbine out on short final, the flight controls seized. He bailed at about 500' AGL and made it.
This is probably more than you bargained for, but it may be informative.
Cheers,

Please define "High Key" for us non-airforce guys.
