The time will come, possibly as a result of this accident, that airshow aerobatic performances will have to be matched to the size of the venue to ensure any accidents remain within the airport boundary or adjacent areas clear of the public. If aerobatics can't be displayed within that area, displays might have to be be limited to flypasts and low-G turns. It would also be interesting to know if G-limited performances of warbirds to extend airframe life actually put the aircraft at greater risk by extending the diameter of loops or increasing the risk of stalls during rolling maneuvers. Rolls and loops seem to dominate in warbird airshow accidents.
