Went there and watched it and was mightily impressed with the whole thing - particularly the flying but also the big screen real time footage and almost instant replays.
I've met quite a few of the pilots and know more of the ground crew and if anyone thinks it is in any way a con or that us mere mortals could get close to flying that course and in particularly that low to the ground is living on cloud cuckoo land.
The telemetry boxes installed in each aircraft apparently cost 250,000 euros each and turning at those speeds will pull that kind of G. The Edge 540s and the MX2 will cruise easily at 190kts IAS and hit 215 straight and level, all with roll rates well in excess of 400 deg/sec.
