I stumbled across a few WW2 accounts were fighter pilots sometimes were barely able to walk after getting home due to exhaustion, and that not due to extended flight time.
Would it be feasible to include a stamina bar into the game? The more Gs you pull and the more you got to "wrestle" with your plane per time, i.e. fighting compression and the like, the faster your stamina bar decreases (which of course regenerates as well). The lower your stamina, the greater the effect on how far you can use your controls. Maybe with a "spring effect", i.e. when you're low on stamina, you can do full inputs, but depending on how low your stamina is, inputs go back to lower values at faster or slower rates. This taking into account initial recovery.
Too complex? Viable?
I'd like to hear what the community says!
