these were innocent people completely uninvolved with the airshow going about their business. Totally unacceptable that they died in such a manner.
And it should be pointed out there is a suitable entirely risk-free airspace ideal for aerobatic demonstrations just a few miles away - the sea front.
Bournemouth moved their air displays from airport to sea-front many years ago with great success. In my view the same should now happen at Shoreham.
