Video Link There may be a better video online but this one will suffice. Now, most individuals would laugh at the prospect of aliens or "E.T" marauding our skies and abducting plebs of all sorts. Of course this would be highly improbable and there are far more reasonable and scientific explanations in regards to certain "sightings" or "abductions" (atmospheric phenomena and sleep paralysis for instance). However, this footage surely is compelling evidence that at the very least, one terrestrial armed force has acquired/developed exotic technology? This craft was detected by at least two ground based radar stations, in addition to the on-board radar of the intercepting F-16 (I imagine the wingman also captured the same data). There were police units who confirmed a sighting of the object (a black triangle supposedly). Furthermore, every time the F-16(s) would lock on to the object with radar, it would react by performing some acute and seemingly impossible manoeuvres. Accelerating from 150-990 knots in mere seconds? It also made some rather sharp turns, some times at 90Â° angles. Now, clearly this object is man-made and I would bet that it belonged (or still belongs) to a branch of the US armed forces. What was it doing in Belgian airspace? I don't know. It's strange that any armed force (air force) would test their aircraft by hovering over a farmer's field or randomly fly over various population centres. One would think if they (who commissioned the aircraft) wanted to test it against modern weapons and detections systems; this could be done easily in a secluded and secure military testing ground. Nonetheless, it does raise some uncomfortable questions. For argument sake; if it was not terrestrial then what was it? If it is terrestrial, then who operated it? If it's American (which I think is the most obvious and plausible explanation) then what are they really doing with such technology? I find it disturbing that such a highly capable craft could penetrate allied airspace with such ease and also with such impunity. Whilst I do not believe UK airspace will suddenly be compromised by black flying triangle crafts, it is not easy to digest the fact that the UK government has scaled back air cover for the mainland. By reducing the number of aircraft that patrol our skies. If such sightings and contacts were to appear over UK airspace, then there is nothing we could do to stop them. You may laugh and dismiss this off-hand, fine. I would do the same. Although it does question how secure we really are here. Surely, a matter at which none should balk.
