The CAA vs. Barke is blatantly unfair. It was a declared emergency and the Sukhoi could have had structural damage, fuel leaks, control problems or anything. Things only a pilot could know and that would not be visible from the chase plane. Or even a radio malfunction. The emergency authority of the pilot overrules any kind of traffic clearance. Besides it was an A/G aerodrome, fer chrissakes.
Adam,
I was at this event and the issue was his departure. He had smoke on and I think the CAA interpreted his actions as trying to show off a few minutes before an airshow started. In doing so he hit two parked aircraft and flew low over a large crowd. Inches lower and he would have crashed into the crowd.
I think the CAA action was entirely justified.
I would agree that the description in the list doesn't quite say this but quite a few of the descriptions seem unclear.
