Torley is unable to find anything of use in the truck, it seems to have been stripped of any electronics it may have once had, though his search, when it reaches the front, does allow him to locate the hydraulic release for the rear hatch (though with the truck on its side it will still need to be muscled into a down position) and a little 4-position control that looks like it has never been used that says, in English, WINCH.
O'Conner is able to find the road, such as it is. The trail is clear in both directions, the way back being a fairly long straightaway that veers off sharply at the point the truck left the road. Looks like their driver had simply dozed off on the stretch and gotten tumbled by an embankment.
