This was probably discussed in depth at the time of the incident in the Azores and only being a member for a couple of months but i'm curious - (I'm not a pilot)
I was watching the "Flying on Empty" dramatization of this incident on Discovery channel last night and got the imnpression that, although the pilots did a fantastic job in landing the a/c successfully, as I understand it they were partly blamed for the incident by not diagnosing the fuel leak problem before turning on the wing cross-feed to correct the fuel imbalance. Surely they were just following the prescribed procedures that were in place as per the manual. Are pilots supposed to try and second guess any problems they might pick up should the manual not solve the problem? Would or could this not lead to an even graver situation? And then the pilots would be blamed as well - Catch 22 situation!
