You giving Weyland way too much credit. Now they pulling up psych evals and know that certain scientists are gonna do dumb shyt at some point to accomplish their agenda and in turn the plot? They're a greedy weapons company thats only worried about the bottom line. Nah man its just bad writing. How the fukk does a geologists that specializes in advanced mapping technology (the flying robots), is an expert on caves, and the spaceship has real-time tracking technology, as evidenced by the fact the captain is able to tell him he saw "something moving" near him (what he later calls "a glitch"), get lost? Still makes no sense. I guess they psych eval'd that storm coming and knocking out their communications too.
