Finally, once completely out of room and careening toward the crowd, the pilot yanked the out of control airplane into the air. It didn't look so much like a 180 as a wingover type maneuver with the airplane impacting as it came down the back side. That said, if you say it made a 180, then it did.

As for what's possible at certain venues, that's where it's a balance between field size, layout, winds, crowd size, crowd control, course rules, operating procedures, and in some cases perhaps even aircraft size (as to what's allowed and not). Not easy to be sure, but I suspect there will be increased scrutiny - I'd predict giant scale and/or turbines first. But time will tell. That said though, it would be wise for any group contemplating a large event to take a real hard look at planned operations - with an eye toward "how would a regulator view what we're about to do?"
