As a resident of a village south of Bracknell, I would be very interested in the source of this article or claim (and the facts)
Yes there have been some seemingly (to the laymen) low flights when EGLL using 09L/R ops, but nothing exceptional that I have witnessed.( Yes the GA traffic and odd vintage aircraft do fly around the area.)
One Bracknell resident quoted in a newspaper, but not one peep from anyone on board, I am sure if they had been exceptionally low, and wobbling about (press/witness words) there would have been someone who will have said something.
BUT, however, saying that, there seems to be some interesting press reports of UFO's in the north Bracknell area, maybe someone has been sniffing the xmas sherry a bit early.
