Re: Update! First Nostromo parts out of the Mold!
My assumptions and directions in the ship are based on us looking from rear to front. From what I can tell, The lift airlock was near a landing strut, presumably the fore strut. This area was on C-deck, presumably the coldest deck when in Planetary atmosphere when the ship was idle,, and extremely hot due to humidity caused by the Atomic reactor or direct starlight heating the hull,- causing a drizzling sweltering heat, depending on outside hull temperature, and engine power output.
Science officer Ash seemed to be the guy manning the airlock, and maybe this explains how he was able to manipulate the alarm to scare the ALIEN out of the airlock in the deleted scene.
It only makes sense that the Lift- (elevator). the lift airlock, and the observation blister are situated near if not directly below the Nostromo's bridge, forward living, admin, and medical compartments on the front 25% of the hull.
The main ladders and elevator must have linked A, B, and the forward more accessable part of "C" deck together.. C deck, Where the food storage freezers, and Compressed coolant (frozen O2), mining survey tractor, and THEN the Front landing claw, behind the bulkhead we saw Brett walking through rearward to look for Jones the cat. It was a massively tall room where the landing strut retracted upwards, taking up space through part of the "B" deck I imagine, and housing cooling plumbing in the upper part of the room, probably this deck had to be accessible to most parts of the reactor for maintenance...thus explaining all of the livable yet utilitarian look...
"B" deck extends towards the most far rear of the ship, ending towards the rear reactor control room, where the windows overlook the horizontal reactor housing extending through a vertical cavern from hull bottom to top
I have a feeling we may be going beyond what the actual designers envisioned, and probably some real help or even a sanctioned bit of guidance would be appreciated from anyone here who might have been anyway involved with the original vision of this ship..
...or then again, maybe we can figure this out ourselves....:love
I will try to make a simple sketch based on what can I see, and leave the details to Space Jockey who has much more experience in the minutia of this ship
