I do not think the UK really has a problem with airshow crashes bar the last couple of high profile ones, the Shoreham crash was caused by entering a manoeuvre too low that it was impossible to recover from, righty or wrongly the main difference in that incident was members of the public not involved with the show died and they hadn't agreed in the terms of sale to accepting ones own liability, the strange outcome of all of this was the display line was moved away from the crowds who had accepted that burden to further areas outside the perimeter of the site, where those that haven't accepted it are more at risk.
Don't most Russian fighters also have a button to put it back into straight and level flight if it all goes pear shaped.
