Thats not really true at leat according to aircrash investigation shows. Crew can make mistakes hours earlier that might lead to a crash or accident later. Mess up something during preflight checks and that can be the issue during later stage. Flights are long.

Screencheat is a fps game that supports 8 player split screen, but I think that is just about it. Is a hassel to set up 8 controllers as xinput only supports 4 and rest will have to be in directinput mode so anyting with more than 4 players is rare.
