If a girl wants to be a pilot let her. But I think you dont see many girl pilots because a lot of girls just dont want to be pilots. As for always seeming like they are in problems thats just because they are over scrutinzed. But in the same breath I've seen girls just plainly get what they want damn the circumstances. Ive been bumped outa my flights before because a female CFI had decided its more important for her student to fly and when I went to complain all I got was "shes a girl get used to it."
And that leads me to think girls either get it easier or harder it just depends on who they need something from.
Sometimes its easy to be a white guy.
