What about things I've seen from airplanes with no windows?

Heck, you can even smell the hamburgers cooking at the airfield
where you're about to land for lunch.

That's the way I prefer to do my flying--- except that time
a bug got in me eye-hole. Didn't make for the most pleasant
landing I've ever done in my career.

(Being a pilot is all fun and games, 'til somebody loses an eye)

P.S.: To the question of why the shades must be up for
landing, they want you to be able to observe events outside
in the event that there is an accident. If there's smoke and
flames, you need to be able to see where they are to make a
decision about which way to run. For the same reason, they ask
you to remove your peril-sensitive sunglasses at such times.
My passengers' always go dead black the moment we leave the
ground in any case.
