Not that recently though. Would have done a good 30 sectors since then.

Sounds like the flight had an uncontained engine failure on the #2 engine.
Some reports say it landed, others say it is still in the air dumping fuel.
Australia's Qantas grounds its Airbus A380 jets, and Singapore Airlines delays flights, after a Qantas superjumbo makes an emergency landing.
Looks like a very big worry for Rolls-Royce though. There were no reports of bird strikes but it's very early.Military intelligence is a contradiction in terms

As for the contained vs uncontained failure bit. Just because outer casing is missing at the rear of the engine does not mean the failure was uncontained. Uncountained is defined as "internal engine parts exiting the casing at very high speed" This would normally mean HP or LP compressor blade departure from the ether the forward area or the rear core area of the engine. This does not look to be the case in this accident. Shock waves caused by the explosion within the engine and heat damage are likely to be the primary cause of the missing casing at the rear.
This is just my opinion and is based on the LIMITED facts available at this time.Military intelligence is a contradiction in terms

An uncontained failure would mean that debris would have exploded out of the engine casing sideways and caused failure to the adjacent structures. The debris looks like it came out of the rear of the engine. Other damage at the rear looks to be caused by heat.

Also look at this picture (taken from a link from the fery article you've linked). Look above the damaged engine. Again it looks like something is protuding from the upper sureface of the wing.

"This issue ... an engine failure has been one that we haven't seen before ... so we're obviously taking this very seriously because it's a significant engine failure," he said.
"It looks like it's an uncontained engine failure but it's too early to speculate and will involve us doing a detailed investigation with the manufacturer Airbus and the manufacturer of the engine Rolls Royce."

Qf a380
Well, I am glad everybody is ok first of all...!
Lets wait and see what RR and QF have to say, after an investigation.
An engine failure of that size, would normally be an internal issue. If it were a birdstrike, it would have been obvious from the engine intake already, feathers & blood usually visible, so would have been quickly reported as such I am sure.
One good thing worth mentioning, it proves these whales can fly about on 3 engines ok, as the incident happened take off +15mins, but after dumping fuel, the landing was at +1H50mins I have read.
As for the press, well, SKY.com had a picture of the engine and wing (as posted here already) and a headline saying "Engine falls off Qantas plane"
scare mongering once again...!

So as my MG slides sideways toward the fuel truck, I am asking myself, "Hmmmm, is it flammable or inflammable, no, no, it's non-flammable that I have to worry about right?"
According to the NTSB isn't the definition of a contained failure as anything that stays in the engine may exit the tailpipe and there is no immediate flight risk. Uncontained comes out the side and does or does not tear stuff up. Potential seems to be the key with no definition being perfect.Live, from a grassy knoll somewhere near you.

One of the photos on this BBC page (http://www.bbc.co.uk/news/world-asia-pacific-11691543 - currently photo 2) appears to shows the fire service jetting foam through a different engine. Same side of the plane, but obviously different engine as it isn't missing chunks of itself.
Is that normal precautionary behaviour? Does it imply there was an issue with a second engine? Is that not going to damage that engine unnecessarily?

Another BBC article that has good quality video out of the window looking at the wing in flight as the plane turns back to Singapore: http://www.bbc.co.uk/news/world-asia-pacific-11691197
Good, calm announcement from the captain too. I'd like to think it would have reassured me if I was onboard...
