Re: Ruh Roh....
had they been loading and it wasn't 6:00 AM, i would have guessed the beers made the ramp 'slippery', but... not the case here. The ramp looks like it has an extremely shallow angle, and might even have some texture to it. I'm surprised if there wasn't slightly more to the story, mechanical failure of some sort maybe. Or he was hitting the gas when he thought he had his foot on the brakes? Happens more than you can imagine!
