Thank you for the video TBM-L!
I was there and was absolutely enthralled with the display. I recall saying to my wife something like "buggered if I know how this got approved, but it's fantastic"; then I answered my own query: "I suppose coz the military can do what they like; bet CASA would never let it happen".
The flying that Snoopy does is actually not terribly difficult or dangerous, and any experienced pilot should be able to fly those manouevres, but to put them all together, into that show, with such skill, was pretty special! On ya Snoopy!
Thanks for bringing it all back!
PS: To answer your question, no I don't think that anyone could condone that display today - because it involves aircraft; but if you're just driving cars and trucks around the arena at high speed, it's probably fine...
