Surely it's unwise to speculate until the exact cause for the crash is made public.
I hope for the pilot's sake they don't attribute responsiility to him though, because the public will eat at him until whatever life he does have after this won't be worth living.
All in all though, it's happened, and the people that have died have left behind families who will be living with the repercussions of this freak accident for the rest of their lives.
The way I see it is - how would I feel if it happened to me ? I'd be seething with anger and hatred for anyone that nonchalantely says ''shyte happens'', these people weren't going to an airshow that day, they were driving from A to B on the road, unaware. I'd feel differently if it were people in the crowd.
Of course banning these shows would be ludicrous, but they need to ramp up the legislation just a little, not much.
We are Britain after all, if you want to throw the dice of death every time you leave the house go and live in Russia.
