And then again, the conspiracy
my good sir, the americans were in a race with the russians regarding this issue.
as we know, the Earth is surrounded by the Van Allen belt ( a lot of radiations, bla bla, living things, bla bla, dead if exposed).
the scientists have confirmed that in 1969 a solar eruption took place. that eruption enhanced the radiations from the Van Allen belt. they've calculated that the spaceship needed a minimum of 1 m of lead insulation for the astronauts to survive the journey through the belt. did Apollo had that kind of insulation? no.
