 The training of you moon astronauts, the Gemini, Mercury, Apollo, was second to none. I mean, even today, it's the gold standard. So you all had that, and you were an astronaut yourself. We'll talk about that in a second. But you had actually had previous experience. You were doing work at Edwards Air Force Base. You were working on some pretty hot airplanes. I think one of them was the Starfighter, which was, as I understand, an incredibly difficult mission.
