That paper you wrote as a grad student concerning the possibility of alien life, what it might look like, how it might function, has come to bite you in the ass. You've been called in on a special team to deal with the downing of an extraterrestrial craft. The craft is remarkably intact. Clearly superior engineering. The crew is nowhere to be found. Another, more militaristically trained team is looking for them. Your job is to examine the interior of the craft to determine what kind of beings the other team is looking for. What do you look for? What clues guide you in putting together a picture of the missing crew?
