A not too dissimilar incident at the 1997 Ostend Air Show resulted in a banning of air shows in Belgium.
Unfortunately it can take a loss of innocent lives for sense to be realised!
Well, that'll be a surprise to the organisers, participants and spectators of the 13 or more airshows organised in Belgium this year. Including one, still to come, scheduling a Hunter...
Whether there was a temporary ban following the accident, I know not; but there's certainly not one in force now.
