Catchfence could have killed Andretti too
Watch this video of racing great Mario Andretti's accident at Indy in 2003. He was in one of IndyCar's flying (literally) machines when he hit a small piece of debris from Kenny Brack's crash and the flying IndyCar got airborne and was ripped apart from the same type of catchfencing that killed Dan Wheldon, only Mario was lucky that his head didn't hit one of the steel poles like Wheldon.
