Very well said F900 and CGB. The main issue here really is why 11 people on the ground were killed. Whilst not wishing to foretell the AAIB investigation, it is clear that it is going to identify many failings - the classics of many accidents.
It is also good to see that things are already changing and that displays are being reassessed. I don't think that this is a case of being risk averse, more a case of being risk aware. The risks of displaying vintage aircraft like the Hunter and the Gnat are real and all those involved with organising such displays need to be aware of the risks and how to manage/mitigate/eliminate such risks. Sat Driver gave an excellent summary of acceptance of risk for the different parties involved. I wonder how many display organisers are truly aware of this?
As I said in an earlier post, this tragedy was avoidable.
