In the beginning it says: crew 17, right? Isn't David accounted as one of them or is there something I'm missing. Going be this list they are 19 in total with Weyland, so that would mean 18+1? Or is one of these names gone completely from the final cut.

Man o man, what happened to all of them, alot of people just went up in smoke. I do hope they fix the crap editing with an "Fixed Cut"
