When I was a Boy Scout, back in the 60's, we were studying First Aid. So the Highway Patrol loaned our 'troop' some 60's movies featuring actual fatal auto accidents. A few scouts had to leave the room. (stop reading here if you don't wanna get grossed out!!!!!) The movies were awful, showing a number of dead bodies, including a dead truck driver. He had been hauling a load of steel pipes and had hit a concrete bridge. The load of pipes impaled the cab of the truck AND the driver. It clearly showed the rescue personnel struggling to pull the dead trucker off the pipes.
I tried searching, but didn’t find anything besides the news coverage of the crash. Give it some time and then try searching liveleak/bestgore/deathaddict and see if anything gets posted.
