 The task force also included 6 flights of F-105s for protection from SAMs, airborne radar support by College Eye EC-121 aircraft, and radar jamming support by EB-66s, escorted by four flights of F-104s of the 435th TFS at Ubon.The planners determined that if the MiGs reacted, their fuel endurance from takeoff to landing would extend to a maximum of 55 minutes.Arrival times of the F-4 flights over the targeted airfields were set five minutes apart to ensure continuous coverage and maximum opportunities for engagement in the target area, and to attempt to run surviving MiGs out of fuel by preventing them from landing.
