Well, many years ago I had a look at this rocket and space craft and concluded it couldn't take off safely? Impressive but ... useless.
And yet hundreds of thousands of people saw a number of Saturn V rockets take off safely.
First of all there was no toilet aboard.
They used plastic bags to piss and poop into. Messy, but doable for a week or so.
And navigation equipment. Didn't work.
How do you know that? Did you test any of the navigation equipment? Are you qualified in astro-navigation (which is not the same as terrestrial navigation)?
Communications to ground. Yes 100's of people on Earth were looking at computer screens but ... they just looked. A trip like this must be 100 automatic, computer controlled but ... no computer aboard. Or on ground.
Actually, most of the trip was computer controlled by several onboard computers. Most of the tough calculations were done on ground based computers and the results transmitted to the onboard navigation computers.
The trans-lunar injection after 2 hrs and 16 minutes took place at the wrong location, at the wrong speed and in the wrong direction so they could never arrive at the Moon to carry out a lunar orbit insertion.
Yes, that's why they practiced a number of times with unmanned probes and landers.
Etc, etc.
*yawn*
Sorry, you don't win my Challange with that old NASA garbage.
Nobody would win even if you personally went along for the trip and saw everything for yourself.
