of course, information raises more questions. But, two witnesses say the craft was moving slowly, perhaps then the pilot made the move to ascend above the deck. tbis is not easy to do without significant forward motion. He could've had a problem with that maneuver and/or in the process ended up in heavier fog, then lost spatial awareness and dropped hard from height, game over.

i'm sure the driver had a plan, but the worse judgment was being there to begin with. others mentioned visibility in fog, etc, turns out in that area the fog moves in/out rapidly, plus the terrain is wicked, trouble written all over it.
