I've started digging through the Blurays and it looks like there's some stuff that might be useful, some Weyland corporate / promo type stuff as well aliens talking - including footage of the old engineer talking that isn't in the extended version of the scene. there may also be an explanation of what exactly the engineer says to David.I'll need to watch it again. there's also a bunch of doco's I haven't looked at yet. (sorry if the fomatting looks screwy, i'm posting from a mobile device).
