Idk, the documentary looks like it is mostly speculation, notice the answers where never very certain.

My question about it being a hoax, is concerning the gravity. yes you can use a string pully system, or something to move the people, but look at the feet. when dirt is kicked into the air, it falls unusually slow. what type of technology back then could have been used to simulate that.

Not saying its not a hoax, or that it is, just wondering what people think, and if they have any ideas.
