Hey, in this place I'm a learner! In any case, there's no place for big egos in aviation - you can learn from others of far less experience than yourself. Believe me, I know that well, and have the bruises on my ego to prove it!
As for JAAs, yes, I am aware that they have brought many problems on our Wannabes. However, I'm not familiar with the details. I'd be very happy to have you fill me in on this thread....
