2011 IndyCar World Championship 15 Car Crash.

15 IndyCars collide at the Las Vegas 300 leaving one racer, 2011 Indy 500 winner, Dan Wheldon dead. 2-3 cars are sent flying through the air 100-200 yards leaving a massive wreck. We have never seen this bad of a wreck before, cars are left everywhere on turn 2 of the track. Drivers had been concerned about the track after practice reaching speeds of 225 mph, on lap 13 their concern became reality. The race was canceled and drivers drove a five-lap salute in Dan Wheldon’s honor. IndyCar CEO Randy Bernard stated Wheldon sustained ‘unsurvivable injuries’, he was 33 years old. An autopsy Monday concluded Wheldon died from blunt head trauma.
