Glons radar confirmed the sighting of an unidentified object at an altitude of 3,000 meters. Semmerzake radar confirmed the Glons detection and passed its confirmation onto the Air Force. The radar scans were compared with the previous Eupen radar sightings (see Eupen Case) by Semmerzake and Glons and were found to be identical.
Several police patrols had witnessed the same phenomenon before. It was a massive triangular shape with the same lighting configuration as seen at Eupen four months earlier.
Colonel Wilfred De Brouwer, Chief of the operations section of the Air Force, said: "That because of the frequency or requests for radar confirmation at Glons and Semmerzake - and as a number of private visual observations had been confirmed by the police - it was decided that as these parameters had been met, a patrol of F-16 aircraft should be sent to intercept an unidentified object somewhere to the south of Brussels"
As a consequence, two F-16 aircraft of the Belgian Air Force - registration
numbers 349 and 350 = flown by a Captain and a Flight-Lieutenant, both highly qualified pilots, took off from Bevekom.
Within a few minutes - guided by the Glons radar - both pilots had detected a positive oval-shaped object on their on-board radar at a height of 3,000 meters, but in the darkness saw nothing. This oval configuration, however, caused the pilots some concern. It reacted in an intelligent and disturbing way when they attempted to 'lock-on' with their on-board radar.
Changing shape instantly, it assumed a distinct 'diamond image' on their radar screens and - increasing its speed to 1,000km/h - took immediate and violent evasive action.
Photographs of the actual on-board radar of the F-16s recorded a descent of this object from 3,000m to 1,200 in 2 seconds, a descent rate of 1,800km/h. The same photographs show an unbelievable acceleration rate of 280km/h to 1,800km/h in a few seconds. According to Professor Leon Brening - a non-linear dynamic theorist at the Free University of Brussels - this would represent an acceleration of 46g and would be beyond the possibility of any human pilot to endure.
It was noted that in spite of these speeds and acceleration times there was a marked absence of any sonic boom. The movements of this object were described by the pilots and radar operators as 'wildly erratic and step-like', and a zigzag course was taken over the city of Brussels with the two F-16s in pursuit. Visual contact was not possible against the lighting of the city.
This same procedure was repeated several times, with this object - whenever an attempt at radar 'lock-on' was made - pursuing a violently erratic course at impossible speed and losing its pursuers.
The famous slide of Petit-Rechain was analysed in the 1990’s by several experts in scientific imagery, particularly by Marc Acheroy (Royal Military School, Brussels), François Louange (Fleximage company, Paris) and Richard F. Haines (Los Altos California); on Oct. 15th 2001, Patrick Ferryn of the SOBEPS gave us this slide, he wanted us to analyse it in our turn using the latest techniques of image numerical analysis, used in the Theoretical and Applied Optics Institute in Orsay. The purpose of this was to compare our results to the previous results, and to outline extra information and if possible draw conclusions about the authenticity of the document and about the nature of the object photographed.
General obversation of the slide
In a first step, we have conducted a visual observation of the film after taking it out of its frame, then a digitisation by transparency using a flatbed scanner Agfa Duoscan T1200. Our observations match those previously made:
- The frame of the picture is perfectly neat and with no split even if it is seen with a very increased contrast; this excludes a double or multiple exposure during the photography.
- It is very difficult to consider faking with a model or any other similar process. This will be confirmed by numerical treatment (see below).
- Video processing or CGI can’t be imagined either: such pictures characteristics are not found on the slide, even by increasing enormously the contrasts.
Even if nothing can be excluded, it seems very likely that the picture is one of a solid object seen on a sky background, object of an unidentified origin to this day.
Digitisation of the picture
The second step was to precisely digitise the slide using a 35mm Canon film scanner with an optical resolution of 2720ppp, which brings a pixel size of under 10µm. That resolution is much bigger than that of the film (around 1µm) but greatly better than the smallest significant details in the picture, which are never under 20µm.
Other than the four very luminous stains, the picture is nearly black and had nearly no contrast. It was thus necessary to have, as early as the digitisation, a noise/signal ratio as good as possible, in order to catch the smallest differences, even in the darkest areas of the picture. For that purpose, we have used a technique consisting in averaging multiple consecutive digitisations: by digitising n times the slide in the same conditions, one reduces the noise part of the image due to the electronic equipment by a factor of 1/sqrt(n).
By digitising the slide in a normal position, then rotated by 90°, 180° and 270°, it is possible to average the fixed noise due to the structure of the equipment (non uniform answers from the bar photosites). To do that, you then need to reprocess the pictures up to the pixel, with an appropriate software, in order to superimpose them perfectly.
It is also possible to reduce the quantification noise influence (i.e. the pixels are coded by 8 bits per colour, that is 256 levels) by averaging the digitisation of the film in ‘positive film’ mode and ‘negative film’ mode, because the answer curves of the scanner are not the same in both modes.
Having then obtained a final average picture in its three components red, green and blue, we kept only a roughly 2 centimetres square, composed of 2430 by 2430 pixels. Finally, given the size of the smallest visible details (about 20µm as said above), we resized that zone to 1024 by 1024 by interpolation of pixels (fig 1.), in order to limit the size of the pictures and the calculation times.
Numerical treatments results
1. A contrasts increase brings out the object shape (fig. 2), particularly on the blue component (fig. 3). That outline is in the shape of an isosceles triangle ABC nearly squared angled on A, completed on its base by a quadrilateral BCED very similar to a rectangle. Taking into account the viewing angle, it is probable that angles A, D and E are square angles, and that the object is horizontal. On the object, very dark, are four very bright stains, that we will call lights to simplify. Three of those lights are close to A, D and E on the object, while the fourth one is situated roughly on the altitude AH of the triangle, from vertex A down to the DE base (fig. 4). It is not possible to estimate the size of or distance to the object, because there is no landmark.
Some areas of the outline are nearly neat while others are blurred, indicating a relative movement of the object and the film. The most believable explanation is that the object has executed a movement during the exposure time, the camera being fixed, but we can’t exclude a small movement of the camera. The two extreme positions are shown on figure 5.
The shape of the observed blurring can be explained by a rotation of the object in space, around an axis going through a point O nearly on the line BC and such that BO = O.25 BC (fig. 5). The rotation angle is close to 5°. We could simulate that blur effect by simulation (fig. 6).
The same rotation also allows to find the whole set movement the four lights underwent, supposed circular on the simulation. However, the three external lights show complex coloured structures and distortions that this global rotation do not explain: the obtained pictures necessarily imply independent movements for all of those lights in comparison with the object.
2. Various colour treatments allow to bring out a luminous halo around the object as well as light trails between the lights, particularly between the central light and the edge ones (fig 7.). However these treatments, in real as well as false colours, do not allow to draw a conclusion about the nature of that halo, nor to be able to precise what are those lights: lighting systems, signal lights or hovering/propulsion systems from the object.
3. Decomposition of the picture in brightness, hue and saturation provides rich information, particularly on the saturation component. This information is substantially improved through frequency filters and colour compositions. Processes have allowed to show privileged directions, especially in the halo that surrounds the object (fig. 8, 9, 10, 11). These directions correspond to the orientations of small luminous grains which, on the picture, compose a sort of rotation around the object, to be compared to snow flakes being flown around in a wind vortex. We can also compare it to iron filings that would be oriented in the lines of a magnetic field. Would that be electromagnetic perturbations, an air ionisation process? Without any available elements, the nature of that phenomenon is difficult to precise, even more because it is practically unspottable on the red, green or blue components of the image. These new observations are even more interesting because they seem to reinforce some theories, like those of the ionic plasma waves, theory used by Auguste Meessen, Professor Emeritus at Louvain University, about the object propulsion (magnetoplasmadynamic propulsion).
Anyway, the existence of those “force lines” is a heavy argument against a faking, which would then be particularly elaborated. Moreover one doesn’t see well a reason why a hoaxer would have undergone the effort to imagine and realise such a complex phenomenon, particularly since it is only perceivable with a sophisticated image processing.
Conclusion
The numerical processing that we executed in Orsay on the Petit-Rechain slide have confirment the major observations already made. They also brought new surprising results about the luminous halo surrounding the object, showing a process in the appearance of a whirl. The nature of the physical phenomenon corresponding could, according to some authors, be linked to the particular propulsion system of the object. That question ought to be investigated further.
Yes, it is possible to take this kind of photo!
During the “non debate” on RTBF, I knew that M. Magain (Astrophysics Institute in Liège University) would not hesitate to underline a technical impossibility: “the slide is suspect due to the impossibility to produce a neat picture using the exposure time used by the witness”. I had forewarned Isabelle Franchimont, who had formally promised me that I would precisely have to answer to that argument. It is the only reason why I finally have accepted to participate in the show.
As I expected, Magain indeed explained his objection, but at the precise moment I was going to answer, the sound from the microphone I was using has been cut! Then the host went on with another chapter. I stood up, decided to reach the center of the stage, have word again, and answer to Magain, but the technicians and Isabelle Franchimont prevented me, guaranteeing that even if I would do it, it would cut out during editing! I therefore have not had the possibility to contradict Pierre Magain.
The process is inelegant because the public will only remember the opinion of one high level scientific. If I could have answered as it was assured to me, it would have only taken a few seconds: I would have only said that Pierre Magain is free to believe that it is impossible to produce a neat picture in those conditions, but that it is not exact! I have even showed it by producing several pictures – neither clearer, neither blurrier – of a model photographed in identical circumstances (see “Vague d’ovnis sur la Belgique”, vol. 1), and that even free hand! I do not pretend that it is the best way to successfully picture anything. The witness, he took care of blocking his objective, wedge it against a wall to avoid as much as possible a movement. Too bad that it was impossible to speak of it…
The analysis of the three colour components (red, green, blue) show that the size of the lights is the same in the three components for the faked photo, but to the contrary is strongly increasing like the wavelength in the picture from Petit-Rechain. This can easily be explained by the process used to obtain the picture of Van Utrecht (a holed mask between the camera and the light source).
In the faked one, the lights movement is the same as the triangular surface. In the picture from Petit-Rechain, it is different.
In the faked one, within a same light, le “light lines” are all in the same direction, which is not the case in the picture from Petit-Rechain.
Conclusion: it is not by using the faking method of W. Van Utrecht that the original slide was produced. The following comments however need to be mentioned:
- it was impossible to demonstrate that the original could be a fake.
- even if it was possible to produce a document in all aspects identical to the slide taken in Petit-Rechain, that would not mean automatically that it is a fake.
- the hypothesis that the Petit-Rechain slide would be a fake cannot be rejected to this date, and maybe will never be, one must then stay careful.
- If the Petit-Rechain slide is an authentic document, nothing proves it is about extraterrestrials.

Care to explain why, how, and what? I am quite adamant that this was *not* any secret US ship for a million good reasons. One does *not* test top secret equipment above a country with 350 persons per square kilometer during 18 months!

The Belgium wave is also one of my favorite cases and it's a shame this thread gets so little attention. I can imagine why the debunkers stay out of this thread because they normally cannot cope with hard evidence. But I would assume that anybody with a serious interest in Ufology would be highly interested in updates regarding this case.

Electronic countermeasures (ECM) are a subsection of electronic warfare which includes any sort of electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems like IR (infrared) and Laser. It may be used both offensively or defensively in any method to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. ...Frequently is coupled with stealth advances so that the ECM system has an easier job. Offensive ECM often takes the form of jamming. Defensive ECM includes using blip enhancement and jamming of missile terminal homers.
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.

The one theory I have which may explain why these craft appeared is that the U.S sensing the Soviet Union may need to be pushed. The Soviets, being alarmed at the latest technology displayed by the Americans sue for peace as it were.
