2007 Alderney, English Channel - a capt. Ray Bowyer, passengers, 2 ATC towers and an additional pilot from a 2nd aircraft.
This case is dynamite. It is a shame there are no photos we know about (photos do not convince debunkers anyway) but nevertheless, there is bags of evidence of a substantial and credible nature. 2 pilots in totally different positions and views of the object(s), multiple passengers, more than one air traffic control tower had radar returns of 2 objects and in the correct position for what Ray Bowyer was reporting, as it happened.
Capt, Ray also had a pair of quality binoculars in the cockpit with him and he used them, while flying, to get a better look!
Basically, unless Ray Bowyer, the other pilot and the passengers are all liars, or saw the same hallucination, there can be no doubt that they saw these collosal objects. There is no need to even go through the usual suspects for mis-identification because man has nothing in the sky that comes remotely close to the size of these. It illustrates just how 'big' the sky is, when really, so few people see things so strange and massive, not far south off the coast off England and north of France!
I don't know why this case isn't championed much more - many are unaware of it - cos it really is up there with the greatest cases ever and it didn't happen in the middle of nowhere, it wasn't at night and it was relatively recent too, proving that good UFO cases do still occur in the modern age.
