Joe,mat UK air shows, no aircraft is permitted to fly over or towards the crowd. There is a display line parallel to the crowd line, but around 100 yards distant (I may be wrong on the distance, but it's something of that order).

The only display aircraft permitted to fly towards the crowd are the RAF Display Team, The Red Arrows, whose skill, airmanship and professionalism is absolutely second to none.

In the case of the tragic accident this weekend, no-one in the crowd of spectators was involved - the aircraft crashed on a nearby highway, outside the airfield perimeter.
