It could well be a long list, but I fear the likes of Duxford and Farnborough are now going to have to have a long hard think about their display regulations.
A very long list, unfortunately. As a somewhat unscientific exercise I overlaid the position of the crash relative to the end of the runway (being unsure of the datum point for the display) over a number of regular airshow venues and in quite a few of them the impact was on a road or buildings. I strongly suspect that the 2016 airshow season will be much smaller than this year, and Duxford and Farnborough in particular will, as you say, be left with much thinking to do.
