Five round red lights perform high-speed maneuvering and 90 degree turns over Cut Bank, MontanaOn the evening of November 11, 2007 at around 2145 hrs, I was getting into the hot tub in our back yard when I immediately noticed four or five round, red objects to the west. They were traveling NW in no specific formation. I thought the objects were parts of a meteor or satellite that had reentered, but after about three seconds they stopped. Two of the objects made 90 degree turns and went opposite directions, with the others staying motionless. The two rejoined the group several seconds later after making some pretty impressive tight maneuvers (that ruled out meteor or satellite pretty quick) and they changed to a SE course.They appeared to be at high altitude and were about 2-3 times the diameter of the stars in the sky. They stayed the same color (red to light red) throughout the sighting, and no noise or other signs were noted. I was able to maintain visual contact with the objects for a total of about 15 seconds until they were close enough to the SE horizon that lights made viewing them difficult.
