As vicious as a wreck gets; front half speared through the Armco, fuel bladder opened, big fire.
Grosjean sat in fire reportedly 18 seconds before freeing himself and scrambling over the Armco.
Medical car was right there and those 2 guys and a corner worker were spraying Grosjean down & helping him over.
I thought he'd been killed until I saw him pop up.
If it weren't for the halo, he'd surely have been killed.
