I'm an "ex- UK airline employee" and now a holder of a "family pass" on an American airline. Of course, as I have now been living in the Mid-East for 15 years, I'm pretty suspect, and I wouldn't blame anyone not wanting me near the flight deck of a PAX aircraft
(Fortunately, there's a few pilots still around who disagree with that theory
Seriously, I agree that if I had been jump seating, there might have been a shade more chance of survival on the "9/11" flights)
