Trivial detail re "drowning" engine #1.
A few posts mentioned the Etihad A340 in Toulouse.
In that case, engines #1 and #2 struck the blast wall, but both engines #3 and #4 kept running.
Engine #4 was indeed "drowned" after nearly three hours, using water and foam, but engine #3 kept running until the fuel was exhausted, because the engine was too close to the blast wall to get enough water and foam into the engine.
The QF32 story doesn't tell so far, if that one fire tender succeeded in stopping the engine or whether more were called in.
The photo seems to show the Trent couldn't have cared less about that one-hose jet....

Was the loud bang a bird perhaps......an albatros?

On the other hand, it clould have been caused by the turbine disc exploding and exiting through the side of the engine and going through the wing.
What do you think?

It's pretty clear that they had no control of the No1 eng, but you have to also ask if they had any control of the failed engine, ie did the start master or fire switch actually do anything when selected on the No.2?

Taking irony to new heights?
You have to love the guy in the black Tshirt (picture 9/56). How many ironic references can you get into one trip with Qantas? Roller derby, no less...

I was talking about the engines' own control systems, not the aircraft's flight controls. Each engine has a controller on it that takes the flight controls' reference command and attempts to meet it. Without this controller, the surge/stall phenomena tends to do bad things to the engine.
I'm sorry, I thought this was a technical discussion forum and not USA Today.

Not only in ZRH, DCS99...
SQ grounded all her A380 fleet pending investigations upon advice of RR and Airbus. Seems this one passed the checks and is now airborne.
This one is really hairy and I think the airlines are correct to be cautious. I've seen almost the identical damage in an A330 a few years back, with a Trent 700, that one was not fun either.

République Française in bed with General Electric
Since AF is not fully independent and is subject to Govt pressure, they will always select a GE engine if available.
The next best thing is the GE/PW Engine Alliance.

211, Prada: RF commanded engine shutdown.
Thanks. You don't really want to add the complexity of spread-spectrum and encryption to what is already a complex system with failure modes. Military and civil safety and reliability are radically different, and should be. If you do need to do this after all, put logic in the FADEC or EEC protocols to detect absence of any wired signals from the rest of the aircraft (FMS, FCC, PFC) - then and only than, change modes and listen for an RF shutdown signal.

YouTube - Airbus A380 Qantas QF32
Have a look at this video. At about 1.00 mins in there is splatter on one of the cowlings. does that look like blood i.e birdstrike, or is it just oil?

All this hoo-ha over an engine failure, albeit dramatic, which was handled extremely professionally by an experienced and well trained Qantas Crew, without any injury to the hundreds of people on board. Bravo Zulu.
I am far more concerned about the recent spate of fatal accidents in which perfectly serviceable airliners were flown into the ground, or into the sea, by supposedly experienced crews.

Heard a so-called expert on Radio 4 just now, from (I think) the Institute of Mechanical Engineers, saying he had a picture of the engine in front of him, and thought it was just a "parts problem". He went on to opine that the problem was related to the exterior of the engine, and that the core of the engine was intact.
Clearly he hasn't seen the picture of the large lump of turbine disc sitting in the back of a truck a rather long way from the core of the engine.
I despair.

As a quick aside, the passenger video recording currently on the BBC News website goes to show that in these situations, the captain should be prepared for his PA to be broadcast not only to his passengers, but also the whole Internet! PS Very 'measured' indeed!
Lets not sweat the small stuff. The big problem is WTF happened to the number 2 engine. The inability to control number 1 would have caused handling difficulties (presumably) but frankly I'd rather the default was the darned thing continued to run, rather than add all sorts of knobs, whistles and microchips that might turn the darn thing off when you most need it.....
If needs be just stick a ruddy great red fireman's switch behind a glass panel on each nacelle, connected to a old fashioned valve......

Neptunus: Agreed, the crew did a superb job. But you only need to look at the photos to see that all the hoo-hah is amply justified, at least from the engineering and maintenance angles. If those wing punctures had been a few cm removed and ruptured the tanks, real horror would be almost inevitable.
