Pool Rack formation seen over an Army Base in Brooklyn, NY during a meteor shower

Some time in the early 1990's, probably around '90 or 91, there was a heavy meteor shower clearly visible over the NYC area. I was located inisde the Fort Hamilton Army Base in Brooklyn, NY. We observed the shower, just over the horizon, through the center and upper level of the Verrazzano Bridge. It was an amazing sight. But when we looked directly overhead, we saw about twelve unknown craft, all bottom-lit and flying in what I could only describe as a group of pool balls in a triangle formation, moving at a high rate of speed.
 These craft were definitely over the "ceiling" and were moving much faster than a passnger jet would fly at the same altitude. The most amazing thing about this sighting was that the UFO's switched positions rapidly, in like an "X" fashion, just as they were flying over my head. all of them did it at the same time, quite rapidly and precisely - it was then that I knew that the only group capable of doing such aerial arobics at that speed would be the Blue Angels.
 But why would they be flying over the city on an average day and at night - and in such a formation? And why were the fighters bottom-lit? Alot about this encounter did not make any sense to me. My natural assumption is that the craft must have been extra-terrestrial. I'm just hoping that I wasn't the only one, aside my cousin, who had my eye on the sky that night.
Date is approximate.  We have assigned an artificial date, allowing for the possibility that the witnesses may have been looking at the Leonid (??) Meteor shower, which we believe is the shower that occurs annually in mid-November.  PD
