I hold yourself in this category too from what I have seen
now I am embarassed...but thanks !
You are right of course, everyone can add a little of their own experiences which people hopefully learn off. I have learned shed loads from these forums, but one must be very careful to filter out those who "give the impression" that they are a shuttle pilot who know everything, and those who really are a shuttle pilot.
I remember in Earnst K Gann's book
Fate is the Hunter, he recounts one flight back from Hawaii. He's been flying with this FO for a while now, and this time he gives control to the FO. His flying is awful and he is quite worried by it. Transpires later that this chap didn't even hold a pilot licence and had just blagged his way in!
I am sure there are a few of those on these boards.....
