Darn it. That was too easy.

It is indeed a 7/8th scale 2D prop for a new film entitled "Flyboys" being made at RAF Halton. Note the lack of shadow. It's very well done & fools a lot of people.
Why didn't you stand behind it to have your picture taken "in the cockpit"?
Not possible I'm afaid. I'm not allowed on that side of the fence. It's parked on the other side of the active runway. I took this shot on full zoom.
