There is a special encounter in which you can encounter a shuttle-craft (USS Torres) that has crashed onto the Earth with three red-shirted men around the craft, all dead from dehydration. On their bodies are "Hypos", which can be used and serve as Super Stimpacks but without the HP-loss side effect.

This is an obvious reference to the Sci-Fi series Star Trek, including the popular trope of "Dead Red Shirts" from the oriignal series in which almost any non-essential character in the show wearing a Red Shirt in an episode was certain to be dead not soon afterwards.

The "USS Torres" may be a reference to one or more people, such as B'Elanna Torres who was a Klingon-Human character from Star Trek : Voyager in 1995-2001, another "Torres" in the first episode of Star Trek : The Next Generation, and finally "Adoni Torres" who worked on Fallout 2 as an Intern Artist.
