The astronauts (approximately 55 were selected by NASA during that period, 24 of whom went to the moon

Astronaut Brian O'Leary told me bluntly, "If there were a conspiracy, Ed Mitchell would have told me about it. No question."

Rocket engineers (if the rockets weren't capable of going to the moon the engineers would know it);

And we would know it today. We learn how to make rockets today by studying how rockets were made for the Apollo program. Proving, for example, that the F-1 engine produces the claimed amount of thrust is a textbook exercise, due Wednesday, show your work.

Any communications or television company who has a satellite in geosyncronous orbit (which is inside the Van Allen Belt so they must know a thing or two about the radiation)

I used to work with these people. Trust me, they'd know if Apollo's information was wrong. There are indeed people today whose job is to design and build spacecraft. They like to think they're very good at it. They like to boast that their spacecraft will last upwards of 15 years in the harshest parts of cislunar space.

Either they're all in on the conspiracy -- all those companies around the world -- or the Apollo data is sound.
