Among the many other video evidences of NASA's own videos using blue & green screens & Hollywood wire harnesses to simulate 'actornauts' in space 'weightlessness'...
This old NASA video on the 66-member countries International Astronautical Federation channel shows a man's head popping up in outer space outside of the space shuttle ( which is obviously a small model ) "launching a satellite into space", oops!
To paraphrase Carl Sagan, "Billions and Billions" of dollars to NASA fraudently siphoned off to secret projects, and they couldn't even catch this man's head accidentally popping up into the video, because they're too busy focusing on producing the fraud to notice their own mistakes
Watch closely at 3:27 to see the man's head popping up in "outer space" to the right of the "space shuttle", and then again at 4:10 when the studio light is turned on and illuminates the entire "planet earth", lol, watch:
