I'd like to add some words but I don't know what to say. First, there is no way in my mind that the van driver got out alive. Sorry. Second, I can't believe the semi truck driver had the presence of mind to unhook his truck from the trailer. It's on fire, someone is dieing back there, he probably realizes that rescue is hopeless and his rig is fixing to burn to the grount. May even have had hazardous or at least flamable cargo so unhooking may have been a dangerous move!
