We had the same deal in the early hours of Wednesday over Rotherhithe.
I assumed that it was a police thing, but there was no searchlight emanating from it, which is normal when the police are tracking something on the ground.
It is very easy to assume that they are there solely to annoy you but presumably there was a valid reason for it.
Regularly drives me bonkers too. A whole hour hovering just over the house at 8 am on a sunday morning the other week.
Its really antisocial and I don't care what the reason is, IMHO its not justified.
Debra, I never heard Met explaining WHY is it sooo necessary to keep helicopter hanging above residential areas at the darkest hours of the night WITHOUT searchlight. Every other week! Even twice or three times a week.
They don't need to use the searchlight - they use infra-red to spot the bad guys. Yes, it is annoying, but they do it for a reason. It kept me awake at 4:30 this morning but if means they catch the villain - I will settle for that.
I was rudely awoken by the same helicopter at 4.20 am - it was hovering right above for ages. If they actually caught someone, then all well and good, but why do they do this in the middle of the night? Don't they collect intelligence that enables them to make arrests on the day shift?
