Their job is something the human race has a hard time grasping. They travel faster than any other human. Higher than any other human (minus astronauts). They’ve basically ascended to a form of reality experiencing greater knowledge and truths, than most people on the planet ever will. Not to mention the sights of the curved earth beneath them. The sound of super sonic flight, the pressures involved. It’s amazing to think about. So much so, that the only identity that suits them, is their faceless space suits.
