Above Enemy Lines
The men of the RAF's 27 Squadron are in Afghanistan for a tour of duty. For two months, they will be flying missions around the notorious frontline of Helmand Province, where British troops are engaged daily in ferocious battles with a resurgent Taliban. In this intimate film featuring cockpit footage, we follow the pilots and crewmen for the duration of their tour, as they deliver troops, food and ammunition, and rescue injured British troops while under enemy fire.
I'm sure the first search result would make interesting viewing, but the second sounds pretty good too!
