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.
Completely agree. I have been flying and involved (in a small way) with airshows for 35+ years. I am horrified and ashamed by this incident. The apologists talk about an 'RAF Ace' and BA Pilot, 'high standards for airshows in the UK' and 'infinitesimal risks' - all of which is admirable and probably true. However, whatever way you look at it, completely uninvolved people have been killed because of others failings and THAT is a crime.
