There's some things I can't talk about openly, but propulsion, engines, and a whole lot of number crunching about fuel sources, so on and so forth. I was going in for an initial meeting before they officially gave me the job, and were going to send me off to the test labs, but then ended up having a wee bit of a debate and ended up owning a repair shop, more or less.
And...well, laddie, it's like the private sector, aye, private owners for profit, celebrities wanting to go into space, basically. Not bound by restrictions or government funding, which tends to fluctuate.
