 The North Vietnamese flew their interceptors with guidance from ground controllers, who positioned the MiGs in ambush battle stations to make their "one pass, then haul ass" attacks.The MiGs made fast and often accurate attacks against US formations from several directions (usually the MiG-17s performed head-on attacks and the MiG-21s attacked from the rear).After shooting down a few American planes and forcing some of the F-105s to drop their bombs prematurely, the MiGs did not wait for retaliation, but disengaged rapidly.
