Unpopular Headcanon, probably.
There is no alcohol on Tracy Island, the scotch and beer you see are alcohol free, because they are pretty much on call 24/7, and just like you don’t drink and drive, you sure as hell don’t drink and fly a rocket, heavy machine, super fast jet or submarine. Nor do people want someone who is unsteady due to alcohol consumption to rescue them.
They probably have something similar to Star Trek.
Nah, that makes a lot of sense if you ask me.
