Lore stuff.
Female pilot's don't tend to have their long hair(if they have it) down when piloting. You know, so it doesn't flap around and get cought on important switches or trapped in an air lock or something.
I was sure there were "up" hair styles, like buns or.. something (Male human here, not very versed in lady hair). Maybe I misread/heard something about it.
Besides, there isn't/wont be hair physics, it isn't that type of game. Maybe a good few expacs down the line when we can walk, IDK.
I want some of what you're smoking.
And re the long hair, I had hair down to my waist and managed fine with a motorbike helmet for 25 years. It's just lazy or placeholder or ineptness. Make your choice.
I'd argue that ME: Andromeda has done a better job...
But that's a bike helmet. it doesn't need to keep a pressurised seal against the vacuum of space. Or the possibility of it. I've also had long(ish) hair with a bike lid. It isn't a problem I agree. But how many fighter pilots have their hair down while flying?
