Object appearing larger than a full moon hovering over hangers moved at varying speeds and made 90 and 180-degree turns.

At age 15, visiting my cousin, whose father was Dept. head, model testing, NCAA (forerunner of NASA) George & I were on the road crossing one of the runways where we stopped at a signal indicating runway in use. My cousin, looking out the driver's side, commented on the full moon. I was looking out the passenger window, observing a much larger object, moon-like in shape which was hovering over the hangers. It began moving, slowly at first, in a straight line, accelerating as a group of 3 F-101 Voodoos began chasing it. The object made 2 90-degree turns and "floated" back to initial position. Minutes later, a group of 3 F-100 Super Sabres did likewise, but the object made 2 spectacular 180-degree turns, then soared directly upward until it disappeared.
