Topic: Back - Red screen while circling
This is a realistic Idea to prevent people from circling in space.
If you always circle(in this case pull up) your blood becomes pressed out of your head by the centrifugal force -> Your eyes can't work correctly anymore and everything becomes black.
If you do it the other way around(pull down) the blood will be pressed into your head and everything becomes red.
When everything is black/red you can't see anything anymore and then your are a victim
This is an effect that is also detected in reality when doing this in an aircraft.
And spacecrafts are even faster, so the effect is bigger there.
