It might be that the re-occurrence of an event of a similar nature to that being discussed, would be lessened if Historic Aircraft, already a finite source, would of necessity be confined to a more sedate display.
I'm second to none in my liking for, and appreciation of, displays of energetic aerobatics flown with panache but, pulling high G loads does not bode well for the extended lifespan of Historic Aircraft airframes.
The public, by and large, attend air displays with a camera and are thrilled and excited by the appearance of their favourite aircraft. Photo opportunities of Historic Aircraft making sedate passes, wing overs, gentle turns are surely all that is required. Pilots and airframes alike could benefit from more restrained displays, thus providing some additional element of safety to the routine.
Seeing the aircraft in restrained flight is almost as good as seeing it demonstrated exuberantly.
