The SAS are based near me and they have some nice helicopters, but I don't think they'd appreciate me taking pictures, the guys positioned outside the base all have submachine guns :/
Since the war has stepped up in the mid east (2 to 3 years now) the helicopter traffic has greatly increased. Every two weeks at least 5 or 6 in formation fly over. I've seen as many as 10 and 12 together. They also fly very low and shake everything. They're the big ones with guns all over. It is very strange.
