Ransom: I'm picking up an increase in atmospheric hydro mounds
Mariner: Yeah, they're called clouds, man.
Ransom: Just to be safe, I'll disengage autopilot and land her manually.

Computer: Ship destroyed. Casualties - 105%
Rutherford: Wait, how did I kill more than the whole crew?

Mariner: Yeah, because it's awesome.

First contact is a delicate, high-stakes operation of diplomacy. One must be ready for anything humanity is interacting with an alien race for the first time. But we don't do that.
