EAA AirVenture at Oshkosh is an absolutely mind-blowing aviation experience. However, the whole time I was there (1999) I felt that an accident was likely, given the way the boundaries were being pushed.
The displays were so full-on that RA (Bob) Hoover's routine in the Shrike Commander, which was to be the highlight of my Oshkosh experience, could only be described as boring.
My feelings of impending doom became a reality when a formation take-off went horribly wrong and a Corsair collided with a Bearcat that had stopped on the runway. There were no fatalities but the pilot of the Corasir suffered extensive burns and was left a paraplegic.
Several of the star performers at EAA AirVenture 1999 are now dead as a result of airshow accidents (ie Jimmy Franklin) or have been severely injured (Wayne Handley).
I was not surprised to hear of the latest accident.
Every pilot, if they get the chance, should go to Oshkosh! Personally, I am glad I have been, but I was equally pleased and relieved to leave. I wouldn't bother going again.

PS: Unfortuately, after Oshkosh, I have little interest in Oz airshows.
