The Airbus A330-300 flight on 23 May “encountered bad weather at 39,000 feet (11.9 km) about three and a half hours after departure” from Singapore, the airline said in a statement. “Both engines experienced a temporary loss of power and the pilots followed operational procedures to restore normal operation of the engines,” it said. “The flight continued to Shanghai and touched down uneventfully at 10.56pm local time,” it said.

thankfully it didn't actually crash
I'm wondering if it just glided and anyone actually noticed
What a horrifying fucking experience.
So did it fall at once or did it gradually glide to that height? The article doesn't specify.
[QUOTE=InfectedPotato;47819894]So did it fall at once or did it gradually glide to that height? The article doesn't specify.[/QUOTE] They can glide fairly well, bad weather probably caused both engines to flameout although it could also be down to plain old bad maintenance.
[QUOTE=InfectedPotato;47819894]So did it fall at once or did it gradually glide to that height? The article doesn't specify.[/QUOTE] Glided. An A330 has a glide ratio of 15:1 - it could have covered nearly 60km during that fall, if they flew it by the books. Although depending on the weather, they may have been in a pocket of descending air, which would have accelerated the drop. And if they didn't position at the right angle/speed, they could have also lost height faster.

[QUOTE=alexguydude;47819839]I'm wondering if it just glided and anyone actually noticed[/QUOTE] They certainly would have noticed the silence.
[QUOTE=Kljunas;47819993]They certainly would have noticed the silence.[/QUOTE] Flying in a plane isn't exactly silent. Even in MD-88/90s with tail mounted engines, you can't exactly whisper. It might have been noticeable, but engines are still run at low speed while cruising.
[QUOTE=Bradyns;47819948]The article has a Flight Radar 24 image showing the altitude/time. [IMG]https://pbs.twimg.com/media/CF8Uw13WIAA-2HP.png[/IMG][/QUOTE] Looks like the drop was over ~25-30 minutes time.

Didn't literally drop out the sky like the article and OP are suggesting.
[QUOTE=InfectedPotato;47820349]So this is just the news trying to make it more terrifying than it really is? Didn't literally drop out the sky like the article and OP are suggesting.[/QUOTE] Yep. News freaking out because of the word "airplane". I swear, one day one of these "journalists" will notice that every plane technically "falls to the ground" when landing and will turn that into a panicked headline.
If anything, the passengers were more comfortable during this "fall" because of the reduced engine noise.
[QUOTE=Daemon White;47820071]Looks like the drop was over ~25-30 minutes time.[/QUOTE] So, nothing that dramatic.

So what did they do? Fly into so much rain it waterlogged both engines? That's an incredibly rare scenario
[QUOTE=alexguydude;47819839]I'm wondering if it just glided and anyone actually noticed[/QUOTE] Wouldn't there have been alarms going off in the cockpit? I doubt there wouldn't be some sort of indicator saying the engines went out.
After reading the thread this event is suddenly super boring thanks guys
[QUOTE=EliteSuperS;47820771]Wouldn't there have been alarms going off in the cockpit? I doubt there wouldn't be some sort of indicator saying the engines went out.[/QUOTE] Cockpit != Cabin. There could be all sorts of alarms in the cockpit but the passengers won't hear a thing. They probably lost non-emergency cabin lighting though - the engines provide power as well as thrust; there's backup systems but they usually cut off non-essentials when on emergency power. Also, alarms in aircraft can be surprisingly subdued. The alarm for "HOLY FUCK YOU ARE ABOUT TO FLY THIS THING INTO THE FUCKING GROUND" is a synth voice calmly saying "Pull up. Pull up. Pull up. Pull up."

Both engines failing is weird. They don't share many of the same resources other than fuel - other than that I thought they operated almost totally independently from one another?
[QUOTE=Trumple;47821941]Both engines failing is weird.

Potentially something like that could have happened here, with rainwater or something.

With that in mind 1'st and business class would definitely hear it. [video=youtube;W5Z-d1Zx02o]http://www.youtube.com/watch?v=W5Z-d1Zx02o[/video] High contrasting audio. (boeing's alarms are basically all the same throughout the KC-707 - 737 - 747 - 777 etc [video=youtube;4hV5spB_aXo]http://www.youtube.com/watch?v=4hV5spB_aXo[/video] In that video you can hear the fire alarm from the cockpit clear halfway up the plane
[QUOTE=InfectedPotato;47819894]So did it fall at once or did it gradually glide to that height? The article doesn't specify.[/QUOTE] I don't know what sort of weather you could get at nearly 40,000 feet that could stall an engine, but since both went out (And one immediately returned) I'm guessing it was weather related. If you pump enough water through one, the engine will sort of starve and shut off. The pilots manually descended while they were following procedure to restart the engines, it wasn't a sudden plunge

Falling 13,000 feet sounds bad until you read they were at 39,000 feet to start with. If they had been at 12,000 feet and dropped 13,000 feet then this would have been a more interesting story.

That second video is not real at all. It is pulling together multiple videos and audio sources to pretend that ryanair sucks or whatever. The alarm you hear is actually a evacuation alarm that is designed to be heard in the cabin to signal a evacuation (this is from the LOT gear up landing a few years ago). The most you would hear if you were in first class were a series of faint dings indicating a master caution and master warning.

I'm not talking about the looped recording either. I'd assume you'd actually have some evidence backing up your claims, but it's not audible without headphones. Either way I don't see enough tell tale signs of the second video being "manipulated" or whatever. :rolleye:
