Dreaded helicopter Why? There is no way any criminals needs chasing around on such regular basis around the same time middle of the night and I thought there were some rules about "exercises" for Police helicopters so why???? Anyone knows? It may not be a police helicopter Anka. Just guessing, but it could be a commercial helicopter doing a regular run back to base. " a commercial helicopter doing a regular run back to base" What going round and round for over an hour? Saturday just gone was very hot and I found it very difficult to sleep, eventually I dozed off only to have the sleep shattered about 2am by a police helicopter going round and round over FP, Harringay, South T'ham for over an hour. For why?
