It's all well and good to claim that pilots should fly the planes and the running of the company should be left to the businessmen, but it's an indisputable fact that the smartest men in the room have managed to turn a billion dollar annual profit business into a $2.3 billion dollar loser in just a few short years. This of course has been due to factors outside their control, but now that a small profit might be on the horizon, everyone is once again slapping themselves on the back and congratulating themselves on how their vision has turned the airline around.
So when you write that pilots have no idea about how to run an airline, then I would suggest that they certainly couldn't have done much worse than the current crowd.
