Transparent saucer followed by F-4 Phantoms

I was driving south on hi-way 281 about 50 miles south of Kingsville tx. when I saw to my right 2 F-4 phantoms about 300 ft in the sky and coming over the road way in front of me real slow that's when I notice they where following a saucer shaped UFO which was transparent. They few across the road and kept going headed to the east
Source of report indicates that the date is approximate.  Witness also elects to remain totally anonymous; provides no contact information.  We suspect that this may not be a serious-minded report, principally because M-D F-4 "Phantoms" would not fly at 300 feet altitude at a slow airspeed.  It would be more likely that they would orbit above a target, maintaining high airspeed, and the advantage of a greater altitude that their target.  PD
