Making the rounds: a heavily modified P-51 Mustang has crashed at the Reno Air Races. The pilot reported a mayday and pulled out of the race, and then the plane looped over and went in nearly vertically, right in front of the grandstands. Death toll is currently at 3, but may climb higher.
Pilots get killed pretty regularly at Reno, but this is the first accident involving spectators I can think of. Unfortunately it wouldn't surprise me at all if this incident shuts down the races for good.
