It was a free show organised at very short notice. Approval was granted in May this year. Given that ,i think what they managed was incredible.
Some of the aircraft were cleared down to 100 feet. How feckin low do you want them ? .
An airfield display will always be better than a seaside freebie with the regulations on out of Airfield displays.
As for the Arrows ? Yes it would have been nice but as they had already been booked to appear in Switzerland what do you suggest ?
It will get better with each years experience.
