If we agree that flying (okay, taking off and landing) tailwheel requires more concentration than nosewheel - then it probably makes them safer!
Steve Fossett didn't disappear whilst trying something extremely dangerous/complicated etc. He disappeared (as I understand) 'heading home'.
It's not the full aerial display that's the danger, it's the 'extra loop chucked in at the end'.
You get my drift.
Just my tuppence-worth!
