CNN is reporting the pilot "sent a Mayday" before "pulling out of the lap" and then going in. I can't figure out how to post a link with my iPad that I'm using now, but at the moment it's right up front on
CNN.com - Breaking News, U.S., World, Weather, Entertainment & Video News.
There's also a BBC report saying 3 dead at this point. It looks bad indeed. Given the current administration, this could well mean the end of air shows in the US. Let's hope it doesn't turn that Draconian.
