As first described by Lieutenant Gorman and by the three witnesses on the ground, the light was small, bright, and clear; no structure was visible; it made no noise and left no trail or exhaust. It was south of the control tower, was traveling horizontally west and northwest, seemingly at high speed, on a straight course, at low altitude. On these points all the witnesses agreed. They did not agree in their estimates of its actual distance and height--a fact that is not surprising when we consider the circumstances. The night was clear and cloudless. It was also dark. The sun had set more than two hours earlier and there was no moonlight (new moon on October 2). On a dark night, the height and distance (and hence the speed) of a moving light of unknown size are notoriously difficult to estimate. According to Lieutenant Gorman, the light when he first saw it was about 1000 feet above the ground and 1000 yards--a little more than ½ mile--from his plane. The three men on the ground saw the UFO, for a few seconds, at different times during a period of less than ten minutes. Like Gorman, they were experienced airmen but they differed from him and from each other in their estimates. According to the assistant traffic controller, the altitude and distance from the control tower were 2000–2500 feet and 1–2 miles. According to the traffic controller, they were 4000–5000 feet and ½ mile; according to the Cub’s pilot, they were 5000–6000 feet and 1 mile. In spite of the discrepancies, these estimates are in general agreement and, together with the details of the UFOs appearance, are consistent with the description of the weather balloon that had been released at 8:50, about ten or fifteen minutes before the UFO was sighted from the ground. The balloon carried a small white light, moved west and then northwest, was at low altitude and slowly climbing, and would soon have disappeared from the view of ground observers. The object that Lieutenant Gorman first saw and pursued was also the balloon, climbing and turning. As it bobbed and swayed in the air currents it would have seemed to blink off and on, just as he reported. Underestimating its height and distance and overestimating its velocity as did the pilot in the Cuban dogfight (p. 42), he tried to follow its apparent climbing turn and, as he stated, blacked out briefly because of his excessive speed. During this interval, short as it may have been, he of course lost track of the object. Shortly afterward, when the UFO passed over his canopy and he dived, he again lost sight of the object.
