SJ Derelict Internal Layout

I think the cave comes after the crash, and is indeed in the crust of the planetoid, dunno how long a cave that size would take....well, anything, to dig out. It may have already been there, because you can clearly see that the ship has only the 3 vagina ports that the Nostromo crew enter it through at the end of the Prometheus trailer where Noomi is looking up at it, and there's an acid hole that they lower Kane through to get to the cave, so if the Derelict crashes on top of a cave easy enough for an acid spewing beastie to scuttle off through the floor into the cave below. Did that make sense? I'm running on caffeine here, haven't been able to sleep so I got up and made coffee.... I have a feeling that the material the ship is made of is organic, and can be molded to whatever use the Engineers' wish it to. So it would make sense if that were the case for the material to continue to grow through the newly acid eaten floor, although it looks more like it is part of the ship as a whole. I don't think I'm making much sense anymore. Time for more coffee......

@Cypher, that makes great sense that the egg chamber grew into the surface of the planet after the crash. I would imagine that a race able to manipulate dna to any form would be able to grow their own tunnels, buildings, etc. Perhaps the acid like you say eats away a hole and then a more 'creative system of goo' builds within the space that has been created.......... Possibly humans stumbling on this process part way through produces monstorous results....................

Someone asked how the derelict ship would have docked with another. If there are three female opennings on this one, might there be three complementary appendages on some other ship or structure that might interface with them? I'm being intentionally polite here.

There's also what looks like a fairly ornate skylight on the exterior of the derelict. It's on the dorsal (top) surface above the three vag-like openings. There are paintings of the interior of the SJ room what looks like rays of light streaming in. I wonder if this is the cockpit or viewport?

Is anyone thinking of the derelict itself as a kind of living creature? Think of an insect like a bee (derelict) flying through the air (space) to land on different flowers (planets) and "pollinate" them? The SJ's simply assist to this end?

Okay some new info. In the computer generated image of the Derelict, it appears there are at least 8 seperate chambers in what we will come to know as the Derelict. The vag like openings are also visiblejust below the center chamber, which makes sense since Kane, Dallas and Lambert go in that way and climb up a bit to get to the SJ chamber (rear center). This definitely puts the big egg chamber BELOW the craft, not inside it. Also, the trailer shows the Derelict taking off from what appears to be an even LARGER a subterranian chamber. Shaw is seen running across the top of (and jumping between?) the doors to this chamber in the trailer. I return to my theory that whatever is happening involves the entire region surrounding the crashed derelict discovered in ALIEN on perhaps a geologic scale, WAY bigger than but, never the less, hinted at by the scale of the egg chamber in ALIEN. Sorry, kids. Seemed easier to find my old thread to persue this discussion. A LOT of new threads since the two recent rtrilers are rehashing old ground STARTED in older threads. Any more thoughts as to layout and nature of the Derelict?
