Hello.
I'm actually looking for details about the Nostromo airlock and, while rewatching the movie in 4K the other day, I was intrigued by what could be written under each sign in the side panels.
If I follow Ron Cobb's semiotic standard concept art, the middle sign is supposed to be "Airlock". So it might be what's written under it.
The bottom one looks like a variation of the "Pressurised area", but I doubt that's what's written under it.
I have not found better reference photos, and even in 4K, I can't read the texts.
Anybody knows or has a better photo of it?
EDIT:
Another image where the same texts appear (inside the airlock) :
