For 6 years, Mr. Callahan was the Division Chief of the Accidents and Investigations Branch of the FAA in Washington DC. In his testimony, he tells about a 1986 Japanese Airlines 747 flight that was followed by a UFO for 31 minutes over the Alaskan skies. The UFO also trailed a United Airlines flight until the flight landed. There was visual confirmation as well as air-based and ground-based radar confirmation. This event was significant enough for the then FAA Administrator, Admiral Engen, to hold a briefing the next day where the FBI, CIA, President Reagan’s Scientific Study Team, as well as others attended. Videotape radar evidence, air traffic voice communications and paper reports were compiled and presented. At the conclusion of this meeting, the attending CIA members instructed everyone present that ‘"he meeting never took place" and that "this incident was never recorded." Not realizing that there was additional evidence, they confiscated just the evidence presented, but Mr. Callahan was able to secure videotape and audio evidence of the event.
