Hangar Bay?

I have just finished modeling a space ship and was wondering if anyone knew of any good tutorials on how to model space ship hangars.

Just do Image search on “Spaceship hanger bay” to get some ideas. There are tons of ideas out there:

Get an idea how your hanger is going to look like. Pick out common elements in hangers, exposed room structures, equipment boxes, light fixtures, Doors, overhead mechanisms, and so on. Make a 3D Model peaces at a time and assemble it in a scene.
