I once visited the Houston Space Centre during some free-time while attending a technical course on Gas Turbine control systems, held on the outskirts of the City of Houston.
As a result, I am one of the relatively few persons on this planet who has walked the full length of a horizontally laid Saturn V rocket. And to my eye, it looked far too small (both in length and diameter) to convince me it could have launched 3 men in suites, alongside a Space Buggy, food and water supply equipment, plus oxygen tanks to last several days ... not to mention several relatively heavy batteries, and a long list of other exotic equipment.
And when I eventually made my way to the Lunar Module (i.e., the weird contraption glued together with aluminium foil, staplers, and a few metal struts) I stood just a few paces away from it ... and within a few breaths I just burst out laughing. "You got to be kidding me" said my mind's eye.
The Apollo Program was (surely) mostly a hoax, that's all I can say. I can't prove it. But neither can NASA prove that all of it's camera work and telemetry [allegedly on/from the Lunar surface] were both authentic.
