Is there anywhere I can find a comparison of the size of Boeing’s Everett plant with a Galaxy class starship from Star Trek?
Here’s some info on the dimensions of the Everett facility, from an article on HowStuffWorks. The smallest dimension is its height, at 90 feet. Also, its biggest doors are 82 feet high, by 350 feet wide.
According to Wikipedia, the dimensions of a Galaxy-class starship, like the Enterprise-D, are:
- Length: 2108 feet
- Width: 1521.4 feet
- Height: 443.8 feet
So, Everett is way too short to build a Galaxy-class ship, and even if it wasn’t, you’d never get the ship out of the door. 
So, you could build the Everett Boeing plant inside the enterprise.
And then you could build Disneyland inside that!
It’s like a turducken! Maybe it’s an Entevdis: a Disneyland, stuffed inside an Everett plant, stuffed inside an Enterprise.
One of my favorite aviation factoids: the Wright Brothers’ longest flight in December 1903 was shorter than a Boeing 747!
I had in mind length and width when I thought about the comparison. Is it possible to overlay a scaled Galaxy class drawing on top of the plant in Google Earth?
When Boeing built the B-52 at their old Plant 2 at Boeing Field, they had to put a hinge on the tail because the roof in that facility was too low. So if you wanted to build a Galaxy Class starship in Everett, would it work if they built the saucer and lower sections separately, and then connected the two sections outside the plant?
I took a tour there. From the balcony, I could see a tiny plane off in the distance, by the door. Turned out it was a 747.
Probably not. If the total height of a Galaxy-class is 440 feet, and the doors at Everett are 82 feet tall, any particular component that you built there could be no more than 20% or so of the total height of the finished ship.
Based on what a Galaxy-class looks like, and the relative sizes of the saucer section and secondary hull, I’d guess that the saucer section, by itself, is at least 1/3 as tall as the height of the total ship, and the secondary hull is even taller.
At Taco Town!
A similar factoid - Kirk’s entire Enterprise is shorter than the Galaxy-class saucer section.
Not only was the Wright brothers’ flight shorter than a 747, but the entire flight could have fit inside the cargo bay of a C-5. Which, relevant to this thread, is also called a Galaxy.
On the other hand, a Samsung could very easily fit inside any of the afore-mentioned facilities.

That’s the Boeing Plant compared with Nimitz class carriers.
Looks like they’ve got some elbow room.
