Well, I ain't gonna lie, it takes a careful bit of calculation. But we have recyclin' systems, so for the most part as long as you're careful and have full tanks when you take off, you can keep goin' for a while. The real problem is when you start usin' it up faster than the ship can recycle it.

I hope you're right. Though I ain't so sure I want to meet whoever the hell brought us here, but - it's probably the only way we're gonna figure out how to get home.
