Stupid.
I'm not a pilot. Too many knobs and buttons for a simpleton like me. I do know about danger though as I have done a lot of jobs that were iherently dangerous. The reason that I am still intact after 50 years is that I always had a plan "b" when I judged that something might go horribly wrong. I seldom had to invoke it but it was always a great comfort to know it was there. I don't think that the pilots of this aircraft had anywhere to go except straight to the smoking hole if there was the slightest human error or mechanical failure. This was an airshow not a theatre of war.
