Good point Helldog. I agree.
However, if your motorcyclist somehow messes up, he will end up in the pile of exploding cars by himself. There is no danger to the public.
If Mr. Hotshot messes up, he will cartwheel through the fields/spectators, towards the houses in the background. And this at 150 knots!
If you do the math, you will find out that 100 tons of A310 airplane doing 150 knots equals a lot more destructive energy than an F16 (15 tons) doing 300 knots. (at 10 feet at an airshow) And THAT is why this was so irresponsible.
....Besides being more manouvreable in an F16 at 300 knots.
....Besides the fireball that would result from around 15000kg of fuel in the A310
....Besides....
