US Student, I am sure these fellows have watched the likes of Bob Hoover (mentioned above) Sean D Tucker and many other great American airshow/stunt pilots perform, just look at some of the flying in the movies. Thats all this was, a stunt performed by a very, very experienced team of stunt/airshow pilots, this was not done by a group of weekend warriors on the spur of the moment.
If the Americans had done it, they would have hailed it as great, which is what it truely was. Take nothing away from these performers, that was a performance second to none. Hats off.
