 On January 2, 1967, U.S. Air Force F-4 Phantom II multirole fighters flew a mission along flight paths typically used by the bombers during Rolling Thunder.The ruse drew an attack by Vietnamese Mikoyan-Gurevich MiG-21 interceptors, whose pilots expected to find heavily loaded fighter-bombers.Instead, they were met by the far more agile F-4s, which shot down between five and seven of the MiGs.
