    Yikes !! :eek:

    I hope the ground-crew were wearing their hi-viz gear ......:)

    However it`s interesting to note that the engine shrouds performed their task and prevented the errant HPT blades from exploring further into the atmosphere ?

    This is how the industry learns....expensive lesson yes,but one which will yield results !


    Men, it has been well said, think in herds; it will be seen that they go mad in herds, while they only recover their senses slowly, and one by one.

    Looks to me that part of the disk escaped and is buried in the outboard side of engine #2.

    What's the lesson to be learned?

    Nice spot. I believe it was number 4 that failed and the part of disk is embedded in number 3 engine.

    This is old news! The incident in question occured on June 2nd 2006 in LAX.

    What your looking at is a Boeing 767 equipped with GE CF6-80A Engines. The number 1 engine HPT stage 1 let go. The picture of the embedded rotor is on the number 2 engine. It let go and cut right thru the underbelly fairings on it travels before embedding in the engine!

    these were always my favourite (3.23 for the exciting bit)


    blade off tests, remember the whole of rolls royce used to hold its breath for those - felt like it anyway

    only ever got up there doing probe icing tests, never for any of the biggies
