Something which just occurred to me while looking back through some of the concept art...
That patch she's wearing on the arm of her jacket has a definite, specific symbol. Does anyone recognise it from symbology/iconography made for the previous films? It could well be something new, but the fact it's appearing twice makes me think it's a badge which symbolises a particular organisation or ship, like the Nostromo/Sulaco, which is relevant to the actual story.
I can't recall anything about the USM stuff from '
Alien Resurrection'. Don't think we got to see any kind of symbol for representing Gateway Station personnel, for that matter.
