When I first heard about the crash I thought the plane was a refurbished WW II standard P-51 and that it was being flown in a Warbird exhibition. I felt bad for the pilot, and for the people who died in the crowd and for the loss of an historic aircraft. Today (Sunday 09-18-11) I read an article in the paper about what happened. It seems that the P-51 had been highly modified for greater speed in an air race. One of the mod's was to remove 5 feet off of each wing tip and to modify the edge of the remaining wing. Couple this with the age of the pilot and the speed and g-forces involved and the chances of a crash increase greatly. To me it seems to have been bad judgment to make these mod's to an aircraft of this vintage and history, and extremely bad judgment on the part of the pilot to fly in the race. I Still feel bad for the deaths and injuries to all those involved, but also feel that it should have been avoided.
