Well last night a 23:30 hours, I saw one of the Met police's EC145s hovering pretty high (though not quite in the cloud) without a single light on, not even anti collision, the heli was simply a black blob in the cloud and I had trouble keeping track of it but for the distinctive noise. It eventually moved of to the north (towards Isle of Dogs)
The Met pilots are civilians on contract are they not? in any case I'm sure they had a valid reason, and there was no mistake, on takeoff the pilot is questioned by the rear observer on whether the correct lights are on.
One more note, the only light I did see was an occasional bright white light shining out of the cabin, I undertsand the ASU do alot of aerial photography and maybe it has something to do wIth this?
Im a curious person and this was something I'd never seen
