The four operators agreed that the object, which they observed for from 50 minutes to an hour through 7x50 binoculars, was circular in shape and with constant brilliance. An airborne C-54 was requested to check the object, which the pilot did, but he reported seeing only a star. The object was tracked at varying speeds from hovering to 300 knots.
