Yeah, I'm not an engineer, but I do love Sci-Fi, and I try to be as realistic as possible in my stories. But wouldn't the launch system, if it was related to gravity control, be pretty slow? And even if it had the ability to negate or lessen gravity, wouldn't temporary, recyclable solid/liquid fuel be more efficient? The best thing to do would be to launch it from a fabrication platform in space, but they didn't have time to build that, and this is the first launch. Time is of the essence, y'know?
