Firstly my sincere condolences to the families of Bill Murton and Neil Rix.
I was there on Saturday and the Firefly display was, upto the accident, very sedate, yet people still keep talking as if the display was full of 'extreme g-pulling' maneuvers. The only extreme maneuver was when they tried to recover from the situation, which was the only bit of flying by the Firefly, that appeared to be screened by the media.
In fact the display appeared to be exactly as many would seem to wish to see for a/c of that vintage, nice gentle flypast down the display line, etc.
As for 'a lot of folk' going to airshows to 'see the potential horrors' what complete and utter nonsense. I've lost count of the airshows/displays I've attended over the past 20+ years and this was the first time I've had the unfortunate experience of witnessing an accident/incident of any kind. If someone is that unhinged, they could have a damn long time to wait and end up spending a fortune to see, what is, a very RARE event!
