You should pause more before speaking of 'things in Europe' as if wherever you are is all of 'Europe'.

I visit a small western French city nearly every year that has an airshow fly out of their small airport (with a nearby French fighter base), yearly, with aircraft spanning WWII era fighters to flyovers from the Patrouille de France and a Rafale.

This, from what I see, is pretty much identical to many USA 'airshows'.
