(Inside the Nostromo spacecraft)
1. Brash (Brett/Ash) asks Dallas, "Tell me, what's the gravity?" ".86, pretty dense stuff." replies Dallas. "Don't tell Parker and Brett, they'll start exploring--" says Brash.
2. "-- before we can find our unknown signal broadcaster!"
3. (Space) The Nostromo space-ship detaches from its refineries. 'POP PIP ZACK CRACK' "The refineries are detached -- let's go!!!"
4. Down on the planetoid, since known as 'Acheron' or LV-426, the Nostromo hovers down to land with a 'FFFF–TOOMM' "Lambert, Dallas and Kane -- search party, alright?" "Suits me!" answers someone. [As day started, the blood red atmosphere of the planet started to lighten --]
Refineries Detached! 
Brett: Academic, Astro Physicist
"Don't tell Parker and Brett..."
"I'm sorry. But, I'm confused..."
I won't give too much away yet - I hope readers. But there's more to Brett than meets the eye.
There's a photo in the novel of Brett - peering quizzically at a piece of discarded skin that he's holding gingerly between a finger and thumb. Even at 11 years of age I was impressed with the costume design. That beaded looking trim around the edges of his jacket. With so little visual source material to go on, it was fun including that detail here.
Ooh Brett, you're so sciencey.
When I finally saw the film years later I was impressed with the design of Ripley's trousers - at the back - when she's walking away from Ash and he shuts the door on her. A very elaborately stitched affair. I don't know how functionally important it was but It tied in nicely with the set design.
The Nostromo here is a sort of Millennium Falcon meets Wall-e. I was ahead of my time! Even the robot in Short Circuit wouldn't appear on the radar for many years.
Yes, she had a nice bottom.
