Tried to read all the comments on here, but I suspect my opinions have already been covered by everyone else above.
The case for me is this: If the CAA's regs can take even one iota of the magic from Shuttleworth, as they have done, then other small shows that are the bread and butter of this industry don't stand a chance.
And take a look at this:
A world champion aerobatic pilot, flying one of the best aerobatic machines ever built, finding new display lines hard to fly. If world champion aerobatic pilots struggle with the new lines, then how on earth is that safer? In order to make things safer, display lines should be easy, common sense and flexible. A pilot should be worrying about flying the plane, and not about whether they're keeping to the rigid and needless set of rules set by the CAA.
In truth, though, I'd say to Shuttleworth, and to all display pilots putting up with this BS; hats off to them.
