Row of White Lights: The plane was designated as America West Flight 564, and was at 39,000 feet near Bovina, Texas, when First Officer John J. Waller and a flight attendant observed a row of white lights which flashed from left to right. The lights were below their flying altitude. Waller immediately made radio contact with the Albuquerque FAA Air Route Traffic Control Center during the observation. Nothing could be found that should be flying in that space at that time.
NORAD Confirms UFO: The next day, the controller made another check with NORAD, and he was told that they had indeed tracked another unknown target the night before that was at first stationary, then accelerated and stopped again very rapidly. These quick darts were estimated at somewhere between 1,000 and 1,400 mph.
Conclusions: There was nothing that could explain the sighting of America West Flight 564, and until another explanation can be found for the unusual object, we must assume that a UFO was seen that night.
The case of America West 564 is a good example of a confirmed UFO by an experienced crew, with confirmation by radar."
