Yes, because it just got dark! Then he talks about the long shadows being “scary” and “forbidding”. All this is line with my supposition that these are subjective feelings.
Anyway, it’s a basic dynamical fact that you have no perception of gravitational fields acting on your body as long as you are in free fall. Einstein built his whole theory essentially on the strength of that idea.
Thanks for the links! The Apollo 11 touchdown brought tears to my eyes. ( I used to have the whole thing memorized! )
