Summary
On December 3, 1957, three F-86L fighter jets from Lockbourne Air Force Base in Ohio picked up an unusual object during a training flight near Parkersburg, West Virginia. The pilots and ground radar operators tracked what they described as a crescent or circular object that glowed orange-red. The object appeared to follow the aircraft for 20 to 40 minutes, moving erratically across radar scopes at an estimated speed of 1.5 Mach (roughly 1,000 miles per hour).
The pilots called it in to ground radar operators at the 783rd Aircraft Control and Warning Squadron in Guthrie, West Virginia, who confirmed they were painting it on their search radar. As the object moved, radar and pilot observations seemed to match up. One pilot said the object appeared to close in range and move away again but did not actually change direction. Another pilot noted that the radar position reports agreed with what he saw. The pilots were careful in their descriptions, one noting that while it might be the moon, it did not behave like the moon.
However, the Air Force investigation reached a skeptical conclusion. The final report noted that the moon was approaching its first quarter on December 14th, and that the visual sighting direction and the moon's position coincided. The investigators suspected a weather inversion, a layer of warm air that can bend light and create false radar images, might have distorted both the pilots' view of the moon and created a radar ghost. The report stated that the radar return was probably caused by inversion effects rather than a physical object. Despite the pilots' protests that what they saw was not the moon, and despite radar confirmation from the ground station, the Air Force classified the case as unknown but with a likely explanation of weather phenomena.
