    The passengers were offered $20 vouchers and had to queue for hours to try and catch another flight.

    I wonder why the pilots just didn't shut off that engine? If they could and it would still fly? Ned, 41 Magnut, BigAL... anyone.

    Also the second link had a longer video and the route was hugging the coast and a couple closer cities and I wonder why they didn't land at one of those providing they had airports that would handle the aircraft.

    Oh the Air Buses. I forgot you were an aircraft engineer aren't you? What caused that engine to shake like that and some of it come off?

    I have no idea, taking a WAG it could be something caused an imbalance in the compressor or turbine, a cowling or gear door came loose and is flopping around in the wind. Sitting here 10,000 miles away, i have no idea unless i am there to inspect the aircraft

    I'm sure that they did cut the engine off but if it ingested something like a bird strike or a fastener and damaged some rotors, it's gonna vibrate a bunch. A nine foot rotor spinning at a little over 3000 rpm with even a little imbalance is going to be felt and shutting it off consists of shutting off fuel and ignition but as long as the plane is in the air, the engine will continue to spin.

    If an engine loses a chunk of its vanes or blades it's going to shake, but this sounds like a huge imbalance. In your washer if a large part of your wash gets on one side it's going to shake. I have no clue what happened here, but I'm still puzzled why the pilot didn't just shut that engine down for the return flight to Perth. I'm sure they had their reasons and I think we'll hear it soon. But it still puzzles me.

    I'm getting to where I don't want to fly anywhere without Sully at the controls,

    :jester:

    OK Steve I got you, but I was under the impression there was some way to stop rotation, like closing some vanes on the intake of the engine? or the outlet? I know in the old Bombers in the 8th airforce they would feather the props to stop engine rotation because it could tear itself to pieces rolling damaged. Believe it or not they could actually over rev. They should have a brake on the shaft to stop rotation shouldn't they?

    Why not feather the blades?

    The blades of a turbine or its compressor are set. They don't have the ability to rotate to a feathered position.

    I was thinking they had some sort of brake on the shaft to stop rotation. I'm thinking that some turbines ( A jet engine IS a turbine) have moveable inlet guide vanes that can be shut.

    That beats the aircraft that landed in Hawaii about 20 years ago with part of the top of the fuselage missing!

    Yep, scare bus!

    I do my best to avoid A320-330's when traveling. I'll take Boeing, Embraer, and Bombardier any day over Airbus.

    The big fanjets on the C-5 would windmill from just a good breeze, and those things had some serious metal to metal clanking noises going on. As soon as a little thrust load was put on the fans, they stopped hitting anything.

    Some years back when I was younger and had fun we had a group head down Deland FL for a group jump. It was hilarious watching people's faces when about a dozen of us boarded a Piedmont Airlines flight with sport chutes as our carryons. While we obviously weren't wearing them, just carrying them on and stowing then in the overhead cause more looks and whispers than a naked Baptist drinking a beer.

    I remember back in 04 getting ready to land in Balad/Anaconda Iraq when the Air Force crew members in the C-17 put on their Flak Jackets (not like the old ones, bigger and different) and said it was up to us to put on our vests/body armor because we were fixin to land and mortars were coming in.........and then sure enough when I left we had to take shelter a few times because they were coming in again.............kinda cool to see your bags strapped on pallets as you were flying.......right down the middle of the aircraft. Some flights have passengers along both sides and cargo in the middle and others had rows of seats in the middle with the bags on pallets in the rear portion.

    Was over the North Atlantic once on a commercial flight to Germany back in the 70s and you know some rough turbulence was coming when the stewardesses shoved the meal carts outta the way and ran to strap in their seats..........with a look of 'Oh Sh.....' on their faces. Pretty much slung stuff around and most of the overheads came open. Would have went airborne in the cabin if not for seat-belts and I guess we dropped some a couple times cause that was all that kept me in my seat like my body was being pulled straight up toward the ceiling.

    They threw a fan blade. You can spin a jet engine with one finger when it's right so a 400mph wind going threw it is going to make it rotate (an shake in this case) at a pretty high rpm.

    I remember that. It was a bomb in the luggage compartment. Sorta blew the lid off.

    If they lost one of the turbine blades, no matter which stage it was from, it would make vibration pretty nasty. Any blade broken loose in the turbine is bound to have caused some other blades to get broken off.
