Yup - note that I said "no danger of a mast strike"!- Referring to earlier remarks about trying it in Huey.................... As you say it looks like a loop but is not - but pretty damned close, and filmed from the right angle is most impressive. We tried similar things in the Wessex 5 but I don't think we got as daring as this chap..........but then again we were strapped to it and the view from inside was a bit minimal.
