Let me say first, the moon landing was real, people can go into outer space, and there are no domed cities under the moon's surface; I'm not conspiracy trolling and this is not about something really happening and being unknown, but possibilities for what could have been done.
But, I just bought "Capricorn One", and an idea struck me. Is it actually feasible that major achievements in space could have been faked? Could pressure ever push a space program (American, Soviet, or other) to fake an event like a Moon landing or first man into space, etc? Could those involved have been thoroughly misled or silenced, and the upper echelon involved willing to allow it? Is it technically feasible? And what would be the ramifications and the ramifications were it discovered?
