Why in Sci-Fi they always use Marine or Naval terminology and structure instead of Aviation for the spaceship structure, navigation and military ranks?
I don't really know how to structure this question, but yeah, why is always Naval and never Aviation?
Doesn't happen with spacecraft either, despite what Hollywood often depicts. In order to 'stop' in space, you actually have to generate thrust. The scary thing that can happen if you lose your engine in space isn't getting stuck in one place, it's smashing into your destination at full speed.
The really scary thing if you lose your engine in space is that you might not smash into anything for a very very long time and die a slow death when you run out of air, water or food.
