The UFO was not observed visually by the F-16s at any time. An analysis by the author, based on distance data, indicates that the object would have had to have been exceptionally large or well illuminated to have been observed visually under the conditions that evening.
1-4: level flight 150 knots; UFO apparently detects interceptor
5: descends 1000 feet
6: resumes level flight, accelerating to 570 mph, 70 degree heading change
7-8: continues level flight, small speed changes
9: continues level flight, slowing, may be losing energy in the entry to the ascent
10: ascends 1000 feet, continues slowing, may be losing energy post ascent entry
11: ascends 2000 feet, regains some speed, turn -60 degrees
12: ascends 1000 feet, regains some speed to highest pre-ascent speed
13: ascends 1000 feet, loses some speed; top of a nearly ballistic trajectory
14: descends 1000 feet, regains speed to amount in (12)
15: descends 3000 feet, turns 60 degrees, increases speed by 200 knots
16: descends 1000 feet
17: levels off, increases speed slightly
18: descends 1000 feet
19: descends 1000 feet, turns 30 degrees, increases speed by 200 knots
20-23: continues descent at 1000 fps with shallow turn and gradual speed decreases
[...] due to aerodynamic considerations, high-G turns (and these are extremely high-G turns), are generally avoided, since they use up the available energy budget for the pursued aircraft more quickly. Yet the UFO made three high-G turns in a span of less than half a minute - and during those turns provided no sign of losing energy (i.e. rapid loss of forward speed). This suggests an extremely high performance vehicle with an unconventional aerodynamic profile
A remarkable UAP (Unidentified Aerial Phenomenon1) has been observed by Lt Col André AMOND and his wife Chantal on December 11, 1989 at ERNAGE near GEMBLOUX in Belgium. We provide first-hand data about all phases of this event and describe the behaviour of the observed lights. These belonged to an object that was invisible to the witnesses and flying very slowly, at low altitude without making any noise. It surprised the witnesses, since it approached closely, turned very sharply and departed at high velocity. During the new inquiry, we found a related observation made by another witness, also in ERNAGE. The facts are analyzed in a rational way and the hypothesis that it could have been a helicopter or any other conventional aircraft is carefully checked, but refuted. Two other cases that so-called sceptics attributed to helicopters are also studied.
1. “The slowness of the movements of the flying object, in contrast to its final rapid motion.”
When I was driving, I had to wait until it caught up, but at the end, it displayed a tremendous
acceleration and flew off at very high velocity.
2. “The mass, which should necessarily have carried the lights, did not reflect the moonlight and
was not visible.” The full moon was positioned, behind the witness. Could its rays have been
deviated towards the rear-side of the object?
3. “The lack of engine noise.” No sound was heard, not even when the car engine was shut off on
the country road, at that time, devoid of traffic. Slightly later, it was possible to hear there the
noise made by a train that was passing much farther away.
4. “For me, it is clear: it was neither an AWACS, ULM or helicopter, nor a hologram”. The Colo-
nel discards thus any conventional explanation, but he insists that “some kind of intelligence was
involved”, since the flying object deviated from its course with a specific purpose. He doesn‟t
know whether this “visit” did result from curiosity or aggressiveness, but it was not accidental.
The motions of the group of lights were always coherent and attributable to a flying object, al-
though the manoeuvre was amazingly slow. The approaching light was very intense, but had a
sharply defined boundary and didn‟t illuminate the ground.
