The Belgian Air Force tried to identify the alleged intruder(s) and, on three occasions, launched F-16 aircraft. On one occasion, two F-16 registered rapid changes in speed and altitude which were well outside of the performance envelope of existing aircraft.

Nevertheless, the pilots could not establish visual contact and the investigation revealed that specific weather conditions may have caused electromagnetic interferences and false returns on the radar screens. The technical evidence was insufficient to conclude that abnormal air activities took place during that evening.
In short, the Belgian UFO wave was exceptional and the Air Force could not identify the nature, origin and intentions of the reported phenomena.
