Here's a cool read about a pilot who flew a helicopter to film some shots over the Abu Dhabi desert.

So that part in the teaser following the Millenium Falcon was because of him. I think that's awesome. Before I couldn't tell for sure if that camera-work was real or not, but now we know for certain it is (with the MF of course added afterward).

He also mentions seeing Simon Pegg having lunch with the crew. Very interesting. So it looks a little more likely he'll indeed have a cameo, even if it might cost him an arm ;)
