    shall we take bets and guesses as to what caused it?

    my money says it was a combustion chamber failure.

    no, too late in the production run, they were back to chains by then...

    might have been a loose oil pump bolt.

    cold starts and not hours are the issues with jets. hours are for piston motors

    Id have expected the damage to be much more catastrophic to the engine engine casing if it had had a wheel failure....

    although I could see it being a final stage wheel... hmmm anyone got a link to the layout of the 380 donk?

    heres the vid of a blade off....

    just caught some new pics from the 10 late news.

    looks like theres damage to the upper surface of the wing not great footage but it almost looks like something came up through the skins..

    according to the Quantas spokes person, I missed his name and job (but I'll be he was someone in charge of something somwhere that has to do with the money saved on servicing... "I think we'll find that it was a defect in a blade and thats a manufacturing problem not a maintenance issue"

    Its a MAF issue.......

    overboost possibly from faulty modulator......

    Ooh oooh, what about fuel in the oil causing it to race out of control......

    But my money is on that something broke......

    Could be either a manufacturing fault or a software/sensor fault that allowed the turbine to get too hot - it was climbing, presumably at or close to MTOW in temperatures way above standard conditions, and would have been operating right at the limit for continuous power. This will be software controlled according to the conditions, and the engine could be run above safe limits either by a software error or by a faulty temperature or pressure sensor. (or the engine is just run too close to the margin to provide the necessary power!)

    Singapore airport is chaos after Singapore Airlines grounded its A380 fleet as well.

    My wife's caught up in the mess trying to get home today. Nothing else seats as many as an A380, so Carol is now on an ancient 777... half their luggage ended up on another plane... 2 hrs sitting on the tarmac sorting it out...

    Fortunately it doesn't happen often.

    Regards
