Military planes are busy round my way?

[Prep Girl]

Might be some thing and nothing but, I over look a few flight paths, I've lived here 6 years , at a guess I'd say I look out on Stansted, City and military flight paths, the planes for the Royal wedding last year flew by me on the way to the palace and then back again, I know the different sounds of the planes, don't hear to many of what I'd call military air crafts but, last few weeks they have been going by a lot, usually at night when I can't be bothered to get up and look but did tonight coz it was so loud , it was a chopper, type you'd see in the war films when they fly in and rescue the soldiers, what's that all about I wonder?
