At this point, it was clear that the storm was a twister. This became even clearer when Suter, wearing only his underpants, was sucked out of the trailer through a collapsing wall into the raging darkness beyond. As death scenes go, this was both extremely cinematic and utterly unsurvivable.
Except that he totally survived. By the time Suter regained consciousness, he was lying four football fields away from the remains of the trailer. The twister had been hurling him around until he ended up in a grass field almost a quarter mile away and across a barbed wire fence. He survived the 150 mph ride with just minor cuts and bruises.
