in the cockpit voice recorder transcript, less than 2 minutes prior to the "big problem", there is this: 2029: 15 CAM- 1 look at that crazy fuel flow indicator there on number four. 2029: 23 CAM- 1 see that. 2029: 35 CAM- 1 some where in here I better trim this thing (in/ up). 2029: 39 CAM- 2 huh? 2029: 39 CAM- 1 some place in here I better find out where this thing's trimmed. ... At 2031: 05 tape damage begins. OK. We know that centre fuel tank exploded. And 1.5 minutes prior to that explosion, there is a "crazy fuel flow indicator" for an engine. Call me newbie, but how come the media have not investigated this or asked serious questions about any potential link between these two events ? Couldn't the initial problems not have been caused by an electrical problem which eventually sparked the explosion ? Could someone put this "crazy fuel flow indicator" in perspective ? Is this something which is as common as someone sneezing and considered perfectly normal ? Also, what exactly did the pilot mean by "where this thing's trimmed" ? Also, how is fuel distributed to each engine ? Is there a single "bus" used by all engines to draw fuel from, and to that bus are valves to each fuel tank to decide where the fuel comes from ? Or do each engine have their own paths to each fuel tank with their own valves to decide where each engine draws its fuel from ? Or do engines draw fuel only from the wing tank under which they are mounted with some pumps to move fuel between tanks, completely independantly from the fuel supply to the engines ? Last question: with a wing tank almost full, what would happen if a pump in centre fuel tank were to start to pump air/fumes from an empty centre tank to a wing tank. Would this cause bubbles/foam to form in the wing tank ? Could this possibly cause an engine's fuel intake to draw some of that bubbled fuel and explain the "crazy fuel flow indicator" ?
