at the time of posting I did not know anyone was injured, I doubt ALFA did either, apologies to all 
When there is no excuse, begging for one is pathetic.

With age comes the wisdom of waiting, even just a couple minutes, before shoving your foot so far up your mouth you have to see a proctologist to get it removed.
Extremely unfortunate incident, I hope much is to be learned from it going forward and that most the wounds will heal quickly for the victims and their friends and families.

Personaly, I've never understood why they just let them race faster, but put the stands and spectators infield, with the deeper you go the greater their massing and protection. You can move the pits out or keep them front and low-stage center (like a bull pen), just price and market the seats infront of the pit and the ones not infront but closer to the race. I've had one friend describe to me their opinion of how the bandstands and spectators are placed and positioned in a way that guerentees the participants/racers will have something soft to crash into when they ineveitabley catapult off the track (and their disbelief that people would actualy pay to be there, and usualy pay more for the faster and more hazardous teh race would be).
