leading fromSpace port in the Solomon Islands?
Near the beginning of Alien, Ripley attempts to hail Antartica Control over the galactic airwaves. "This is commercial towing vessel Nostromo, out of the Solomons".
We might ask where in the cosmos the Solomons might be as if we were to assume this is where the ship had just come out from there.
However later we find in a time line given in the Alien Quadrilogy set released in 2003 that a Space port established is in the Solomon Islands on planet Earth.
The information in this time line for the characters we would assume is at least partly based on Ridley Scott's notes for the character's backgrounds that was going to be included with the original Alien dvd but never was.
How much of the information is valid we don't know, because it includes additional information which would surely not have been included in Ridley's original notes.
A question might be about whether the fact that the Nostromo is a mining vessel out of the Solomons is a straight reference to the book King Solomon's Mines Sir H. Rider Haggard?
Nostromo and Kings Solomon's Mines both are set in a world where they're searching for precious metals and were published at the turn of the 19th/20th Century within 20 years of each other and maybe who ever invented the Solomon Islands space port idea simply took the reference into a different context afterwards.
No one is supplying an answer.
c) Houston changed to Solomons
In 2009, Alien's editor Terry Rawlings allowed documentary maker Dennis Lowe to scan his editing script.
On page 8 of this copy of the script with extra information written in pen, Ripley is found to announce over the airwaves on the transmission unit, "This is commercial vessel Nostromo, out of Houston".
Although it was coming back from the another part of the galaxy beyond the outer rim, here scribbled in is the seemingly secret fact that reveals the Nostromo is being reported to have come out of a space port on Earth and so a quick idea was to add the name Houston and later a decision came to change it to the Solomons.
