I don't know about that. Here's an Oberth scaled to 120 meters overall length against a Nebula at 444 (based on its having the same saucer width as the Galaxy classs). The deck heights are the same in this comparison, and notice that deck 10 of the Nebula is exactly where it should be. Compare this against the closing scene of GEN, and it's not so bad. I guess I should make the shuttles in the Nebula a little smaller, since the type 8 is only 2.8 meters tall.
