On 30 March, around 2300, the Belgian police was called by an off-duty police officer, who observed with his wife and another couple UFOs in formation seen in the night sky in the area general area of Wavre. It was, once again, the “unplanely” appearance and behavior that caught their attention. The objects were described as moving in an unpredictable way, with lights appearing and disappearing, and changing color to include white, blue, red, and green. The witness then called the Beauvechain military base and at that point the lights became slower, and maybe stationary, and turned into a red color. The witness was told to contact Glons NATO radar station instead, as Beauvechain was on minimum manning because it was the weekend, which he did (p. 180). Wavre is about midway between Brussels and Namur, while Glons is about 15 km north of Liege (see map).
• At 0013, the first combat radar lock-on occurred, but in 3 seconds the object went from 150 to 970 knots (280 km/h to 1890 km/h) and dropped from 9000 to 5000 feet. A few seconds later it returned to 11000 feet and quickly to down to ground level (p. 227).
• At 0030, there is the second lock-on for 6 seconds; the combat radar system very briefly showed a jamming signal on the in-flight screen (p. 227). At the same time, police officers and witnesses on the ground saw the lights of the F-16 turning around in the sky, while most of the UFO lights went off (p. 227).
• Between 0045 and 0100, the fighter jets still tried several interceptions again, but to no avail (pp. 227-228).
• At 0106, the police informed the military that a similar observation was made at Joidoigne (p. 228). Joidoigne is about 20 km east of Wavre (see map).
• At 0130, witnesses (including police officers) reported that the last lights in the sky were gone (p. 186).
• Beyond the police officers and the civilian witnesses already noted, at least 7 other reports confirmed the observations of the night (pp. 197-190).
After these events, the Belgian military launched an investigation to understand what happened. This led to the drafting of the Lambrechts Report (from the name of the author, a Major in the Belgian military), and an English version is available here. The Belgian military could not find an explanation to what happened. In June of the same year, the Report was publically released and the Belgian military made all their data available for further analysis by SOBEPS and whoever is interested in studying them.
