Donald Miller is my kind of guy: not only does he dig Nostromo model kits, he likes to craft diagrams to illustrate just how big she is.
I have not seen many scale drawings of the ship compared to real-world vehicles, but today I came across Donald’s comparison with Lockheed Martin’s workhorse of the sky, the C-5 Galaxy…

…in comparison with this monster:

So, how do they measure up?
Here’s what Donald has come up with, over at his Flickr photostream:
A look at the film and the C-5’s specs show us:
Nostromo’s tow-load is 20,000,000 tons.
C-5 Galaxy’s max. payload is 143 tons.
Nostromo’s length of 800-feet is referenced in Starlog Magazine #23 (June 1979), page 24.
Specs on the C-5 Galaxy state that it is 248 feet long.
The exact dimensions of the Nostromo are debatable, but you have to start somewhere when you make these diagrams, and I think Donald’s done a nice job here.
