Alright so your idea seems way to basic, I'll help you get yourself some imagination on this topic : find a normal unarmed plane, our ship are as far as you get from environment friendly, just imagine someone going down with his fucking Anaconda, like do you know the size of these motherfucker ? It's the size of a aircraft carrier, now image 10 of that flying around Earth. Hell nah, go down to Earth, yes, but do normal earthy things, and flying a warship under a bridge while spitting your hydrogen fuel in the ocean ain't part of it.
No, I think that with the technology in elite, planets that doesn't have bubble should be big enough to have a controlled space. You cannot enter the atmosphere with a god damned space ship and you come down by Space Elevator. You should also get finned the fuck out for flying a space ship around a inhabited habitable planet ( and I'm talking millions boys ) We should get a specific ship launched plane for that.
Now, I'm just talking logic here, I'm not saying FD is going to do that, but if they are going for it they might as well do it right.
