REPORT ON THE OBSERVATION OF UFOs DURING THE NIGHT OF MARCH 30-31, 1990
a. This report
gives an overall view of the reports from the concerned Air Force units
and of the reports from ocular witnesses of the gendarmerie patrols, about
the unknown phenomena watched in the air space (hereafter called UFOs),
south of the axis Brussels-Tirlemont, during the night of March
observations, visual and radar, were of such a nature that the take off of
two F-16 of the 1 J Wing has been decided, in order to identify these
c. This report
has been established by Major Lambrechts, VS/3 Ctl-Met 1.
beginning of December 1989, strange phenomena have been regularly noticed
in the Belgian air space. The Air Force has at its disposal several ocular
witnesses, most of them having been informed by the gendarmerie. The Air
Force radar stations could not confirm, in any case, up to March 30-31,
these sightings, and the presence of the UFOs could never be established
by the fighters sent in that order. The Air Force staff has been able to
produce several hypotheses about the origin of these UFOs. The presence or
the testing of B-2 or F-117 A (stealth), RPV (Remotely Piloted Vehicles),
ULM (Ultra Light Motorised) and AWACS in the Belgian air space during the
facts can be excluded.
The cabinet of
the MLV (Ministery of National Defense) has been informed about these
discoveries. In the meantime, the SOBEPS (Societe Belge d'Etude des
Phenomenes Spatiaux) got in touch with the MLV, in order that the MLV
backed the SOBEPS in its inquiries about this phenomenon.
has been accepted, and after that the Air Force has regularly cooperated
with this society.
Chronological summary of the events during the night of March 30-31, 1990.
23 h 00: The
supervisor responsible (MC) for the Glons CRC (Control Reporting Center)
receives a phone call from Mr. A. Renkin, gendarmerie
certifies to see, from his home at Ramillies, three unusual lights towards
Thorembais-Gembloux. These lights are distinctly more intense than stars
and planets, they don't move and are located at the apexes of an
equilateral triangle. Their color is changing: red, green and yellow.
23 h 05: The
Glons CRC asks the Wavre gendarmerie to send a patrol at this place in
order to confirm this sighting.
23 h 10: A new
call from Mr. Renkin points out a new phenomenon: three other lights move
towards the first triangle. One of these lights is far brighter than the
others. The Glons CRC observes in the meantime an unidentified radar
contact, about 5 km north of the Beauvechain airport. The contacts moves
at about 25 knots towards west.
23 h 28: A
gendarmerie patrol including, among others, Captain Pinson, is on the
premises and confirms Mr. Renkin's sightings. Captain Pinson describes the
observed phenomenon as follows: the bright points have the dimension of a
big star(*); their color changes continually. The prevailing color is red;
then it changes itself in blue, green, yellow and white, but not always in
the same order. The lights are very clear, as if they were signals: this
enables to distinguish them from stars.
23 h 30 - 23 h
45: The three new lights, in the meantime, have drawn closer to the first
observed triangle. In their turn, after a series of erratic moves, they
arrange themselves also in triangular formation.
In the mean
time, the Glons CRC observes the phenomenon on radar.
23 h 49 - 23 h
59: The Semmerzake TCC/RP (Traffic Center Control/Reporting Post) confirms
in its turn to have a clear radar contact at the same position pointed out
by the Glons CRC.
23 h 56: After
prerequisite coordination with the SOC II, and since all conditions are
fulfilled to make the QRA take off, the Glons CRC gives the scramble order
to the 1 J Wing.
23 h 45 - 00 h
15: The bright points are still clearly observed from ground. Their
respective position does not change. The whole formation seems to move
slowly in comparison with the stars. The ocular witnesses on ground notice
that the UFOs send from time to time brief and more intense luminous
signals. In the mean time, two weaker luminous points are observed towards
Eghezee. Those, as the others, have also brief and erratic moves.
00 h 05: Two
F-16, QRA of J Wing, AL 17 and AL 23, take off.
Between 00 h
07 and 00 h 54, under control of the CRC, on the whole nine interception
attempts have been undertaken by the fighters. The planes have had,
several times, brief radar contacts on the targets designated by the CRC.
In three cases, the pilots managed to lock on the target during a few
seconds, which, each time, induced a drastic change in the comportment of
the UFOs. In no case, the pilots have had a visual contact with the UFOs.
00 h 13: First
lock on the target designated by the CRC. Position: "on the nose" 6 NM
(Nautical Miles), 9000 feet, direction: 250. The target speed changes
within minimum time from 150 to 970 knots, altitude coming down from 9000
to 5000 feet, then up to 11000 feet, and, shortly after, down to ground
level. From this results a "break lock" after some seconds, the pilot
losing the radar contact. The Glons radar informs, at the moment of the
break lock, that the fighters are above the target position.
+/- 00 h 19 -
00 h 30: The Semmerzake TCC as well as the Glons CRC have lost contact
with the target. From time to time a contact appears in the region, but
they are too few to have a clear track. In the meantime, the pilots
contact on VHF the radio of the civilian air traffic, in order to
coordinate their moves with the Brussels TMA.
contact on UHF is maintained with the Glons CRC.
00 h 30: AL 17
has a radar contact at 5000 feet, 20 NM away Beauvechain (Nivelles),
position 255. The target moves at very high speed (740 knots). The lock on
lasts during 6 seconds, and, at the break lock, the signal of a jamming
appears on the scope.
+/- 00 h 30:
The ground witnesses see three times the F-16 pass along. During the third
pass, they see the planes turning in circles at the center of the great
formation initially seen. At the same time, they notice the disappearance
of the little triangle, while the brightest, western point of the big
triangle moves very fast, probably up. This point emits intense red
signals, in a repetitive way, during the manoeuvre. The two other points
of the great triangle disappear shortly after. The clear points above
Eghezee are no longer visible, and only the western brightest point of the
triangle can be observed.
00 h 32: The
Glons and Semmerzake radars have a contact at 110 / 6 NM away Beauvechain,
which heads for Bierset at 7000 feet and high speed.
speeds go from 478 to 690 knots. The contact is lost above Bierset. The
Maastricht radar control center has had no contact with this UFO.
00 h 39 - 00 h
41: The Glons CRC mentions a possible contact at 10 NM from the planes,
altitude 10000 feet. The pilots have a radar contact at 7 NM. Again is
noticed an acceleration of the target from 100 to 600 knots. The lock on
lasts only a few seconds, and the planes as well as the CRC lose the
00 h 47: The
Beauvechain RAPCON mentions a contact on its radar, at 6500 feet altitude,
position away Beauvechain: 160 / 5 NM. The Glons CRC has also a contact on
the same position. This one is observed up to 00 h 56.
00 h 45 - 01 h
00: Some attempts are undertaken in order to intercept the UFOs. The
planes register only a few very short radar contacts.
observers see the last UFO disappear towards Louvain-la-Neuve (NNW).
Around 01 h 00, the UFO has completely disappeared.
01 h 02: AL 17
and AL 23 quit the frequency of the Glons CRC and go back to their base.
01 h 06: The
Jodoigne gendarmerie mentions to the Glons CRC that has just been observed
a phenomenon like the one observed by Mr. Renkin at 23 h 15.
01 h 10:
Landing of AL 17.
01 h 16:
Landing of AL 23.
01 h 18:
Captain Pinson, who in the meantime has gone to the Jodoigne gendarmerie,
describes his observation as follows: four luminous white points at the
apexes of a square, the center of which is Jodoigne. The UFO seen towards
Orp-Jauche (SW of Jodoigne) is the brightest and has a yellow-red color.
The luminous points move with jerky and short moves.
+/- 01 h 30:
The UFOs lose their luminosity and seem to disappear in four distinct
a. Meteo. The
data mentioned by the Air Force Wing Meteo regarding the concerned area
and during the night of March 30-31, 1990, are the following:
to 15 km with clear sky. Wind at 10000 feet: 50/60 knots. A slight
temperature inversion at ground, and another, as slight, at 3000 feet.
These data are confirmed in Captain Pinson's report. He mentions also that
the stars were clearly visible.
b. Because of
lack of appropriate material, the ground observers could not make any
photo or film of the phenomenon.
c. The UFO
observed with a telescope is described as follows: a kind of sphere, a
part of which is very luminous; a triangular shape could also be
distinguished (For a more detailed observation, see Captain Pinson's
report, in appendix H1).
contradiction with other pointed out UFO sightings, for the first time a
radar contact has been positively observed, in correlation with different
sensors of the Air Force (CRC, TCC, RAPCON, EBBE and F-16 radar), and this
in the same area as visual observations. This has to be explained by the
fact that the March 30-31 UFOs have been noticed at +/- 10000 feet
altitude, whereas in the former cases there was always talk of visual
contacts at very low altitude.
b. The visual
evidences, on which this report is partially based, come from gendarmes in
duty, whose objectivity cannot be questioned.
c. The UFOs,
as soon as seen by the F-16 radar in the "Target Track" mode (after
interception), have drastically changed their parameters.
measured at that time and the altitude shifts exclude the hypothesis
according to which planes could be mistaken for the observed UFOs. The
slow moves during the other phases differ also from the moves of planes.
d. The fighter
pilots never have had visual contact with the UFOs. This can be explained
by the changes of luminous intensity, and even the disappearance of the
UFOs, when the F-16 arrived in the neighborhood of the place where they
were observed from the ground.
hypothesis according to which it was an optical illusion, a mistake for
planets, or any other meteorological phenomenon, is in contradiction with
the radar observations, especially the 10000 feet altitude and the
geometrical position of the UFOs between themselves. The geometrical
formation tends to prove a program.
f. The first
observation of the slow motion of the UFOs has been made roughly in the
same direction and with the same speed as the wind.
differs by 30 degrees from the direction of the wind (260 degrees instead
of 230 degrees). The hypothesis of sounding balloons is very improbable.
The UFOs altitude during all this phase remained 10000 feet, whereas the
sounding balloons go on higher and higher, up to burst at around 100000
feet. It is difficult to explain the bright lights and changes of color
with such balloons.
It is very
improbable that balloons stay at the same altitude during more than one
hour, while keeping the same position between themselves. In Belgium,
during the radar observation, there was no meteorological inversion in
progress. The hypothesis according to which it could be other balloons
must be absolutely dismissed.
speeds greater than the sound barrier have been measured several times,
not any bang has been noticed. Here also, no explanation can be given.
h. Though the
different ground witnesses have effectively pointed out eight points in
the sky, the radars have registered only one contact at the same time. The
points have been seen at a distance one from another sufficient for them
to be distinguished by the radars also.
explanation can be put forward.
hypothesis of air phenomena resulting from projection of holograms(*) must
be excluded too: the laser projectors should have been normally observed
by the pilots on flight. Moreover, the hologram cannot be detected by
radar, and a laser projection can be seen only if there is a screen, like
clouds for example. Here, the sky was clear, and there was no significant
