KIRO-TV in Seattle is just reporting this news out of SFO, a Qantas 747 had an exploded engine and returned. No other details; here are images of the plane:

Here's the audio, starting with Tower before takeoff, and going all the way through to Ground after landing. 17 minutes. Very interesting.

Here's more of the story, and another good picture.

Eric M: Awesome! Sorry for being lazy on this one.

By the way, on SFO tower at least, rescue services come one at 742Z (so before the handover), if not before.


hey, if there's a partial containment failure, I'm cool with calling it an explosion. If even one bit o' titanium flies out at an unanticipated angle, that counts.

Would you call the Challenger accident an explosion?

Indeed I would! After all, one of the SRBs suffered a partial containment failure. The SRB was mostly intact when it was recovered, but you'd be justfied to say that it exploded.


(Oh yeah, so did that big-ass Liquid Fuel Tank, and the orbiter, but that was later).
Yeah, explosion is when parts blow outwards. For rockets and jet turbines, it's a problem. When bits of titanium that are spinning at 20k RPM bust out of their containing nacelle, bad things can happen. Look at the hole: it's pointing away, but when it went, there was a 1 in 4 chance that it would be going somewhere sporting.

After spending all morning with the associated feed archives, I've pieced together an entire audio transcript - but it's 17 minutes and 8 MB in size, and I can't get it to upload for the life of me. Will keep trying........

Edited to add: All done. The audio is in the first post. After the four hours I spent on this, I hope at least one of you will listen.  cheesy

Rock on Eric, (re-)listening, on the principle of the thing.

Thanks! I spent a good 40 minutes alone just figuring out that the sample rate was different in the audio between the various feeds. If you hear anything that sounds like Alvin & The Chipmunks, let me know. I think everything is good now.

Also, in light of the controversy over what constitutes an explosion, I have renamed the thread appropriately.

Thanks for the audio work!
Quite remarkable recording, almost 18 minutes of related audio...

Luckily the blade (or whatever else broke) exited at the engine's side facing away from the plane. Any other direction could have caused more trouble - damaged the wing or #3 engine to the left. "Just" loosing one engine didn't really thrill the Aussie pilot too much. No worries!  grin

Nothing Like A 747!

Not an explosion.

Agreed. This is what we call an "Uncontained Failure". My guess would be in the turbine section, judging how far aft on the cowling the breach is.

There was no fire. The "fire" seen by passengers is caused by engine surge.

Qantas B747-400s are powered by Rolls-Royce RB211 high-bypass turbofan engines. See the pic below. The turbine section is directly behind the burner section, about the area of the breach. Again...just a GUESS!  wink

By the way...GREAT CATCH ERIC M!!

Not to be rude, but a minor correction here  evil I think this area is called compressor area, the entire engine is a turbine and sections of it are compressor stages  huh
