As they were flying a DC-8 charter cargo plane from St. Louis, Missouri, to Dallas, Texas, two anonymous pilots observed an object over southeast Oklahoma. They had just commenced a gradual descent from 21,000 feet in the vicinity of McAlester when the object appeared off to their right, approximately 5000 feet away, and moving in the same direction. It gave off a strange orange light and abruptly rose straight up like an elevator, then made a right angle turn in the direction of the DC-8 and approached at incredible speed, taking a position about 300 yards away, slightly above them. It was disc shaped, with a clear dome on top, and continued to pace the airliner in the new position. The pilot tried to raise its air traffic controller by radio with no success. The moonlight reflected off the silvery sides of the object, which had two sets of raised fins along its trailing edge; it appeared to be about 75 feet long and 40 feet wide. The pilot switched on his radar and immediately picked up its echo on the scope; almost instantaneously the object began a series of complex maneuvers and took up a new position just below the leading edge of their left wing. It dropped to a position 300 feet below the aircraft and the two pilots were able to see two, perhaps three, indistinct and shadowy figures inside the dome; the object then moved out and ahead of the plane, executed several more maneuvers, and disappeared into the night.
