Turning about with a helo was always just a bit of fun to try and get a guns solution. The battle had been over with a Fox 3 and Fox 2 on the way to the merge. Of course you could always go supersonic over the top that would wipe out the helo - in the same way a low level Tornado did to a Winnebago back in the early 90s on a Red Flag. Surprised the Winnebago driver didn't have the supersonic area marked on his road map!!! Luckily, the driver got away with bumps and bruises (and a new campervan).
