[QUOTE=jordguitar;47822430][IMG]https://i.imgur.com/bPsejqO.jpg[/IMG] You were saying?[/QUOTE] That you don't know what you're talking about? [video=youtube;l4766-wb0cE]http://www.youtube.com/watch?v=l4766-wb0cE[/video] A deck alarm is not an evac alarm.
[QUOTE=gman003-main;47820374]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.[/QUOTE] Sounds like an Onion headline; "Plane falling from the sky safely landed at LAX, suicidal captain calls it 'routine'"
[QUOTE=TheTalon;47822154]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[/QUOTE] It's a dangerous down wards type of pressure that is created by certain supercell storms, there was once a such disaster at an airport when it lost altitude really quickly and the front of the plane hit a fuel storage tank, luckily those in the back managed to survive, in such cases you can easily fall out of the sky, you don't even need to stall for that to happen.
[QUOTE=Matthew0505;47820455]I'd assume when they said the engines lost power they weren't running at all.[/QUOTE] 'Lost power' is airline codespeak for 'The engines fucking died'. Seems to me to be a case of simply sucking in enough water from the storms to put out the flame fronts between the two turbines in the engines, since they restarted normally at a lower altitude(Denser air --> more O2 present --> easier to sustain the flame front in the engine) and it flew just fine for the rest of the trip.
That's seriously one those fears that you have flying thinking "oh crap this is actually happening to me now". I know that had I been on that flight, considering how often I've flown in my life, I would have assumed my time was most certainly up.
My Mum told me that the aircraft glided down slowly and most of the passengers didn't even know about it. Apparently the glide was very controlled by the pilots. She works in customer relations for SA and not one person has yet to complain about it.

The Gimli Glider (767) glided about 70nm to a safe landing. The nose wheel didn't lock when it dropped so it collapsed and the plane slid to a stop. Sparks flew, a fire broke out, but everyone made it out Even harder to believe is in only 2 days they repaired that plane enough to fly it out of Gimli. It under went some more repairs, and was put back into service until it was decommissioned in 2008, 23 years later.

[QUOTE=Adlertag1940;47822086]Alarms in at least boeing are by default maximum volume and additionally the alarm speakers act as a megaphone / loudspeaker for the captain and co captains headsets in case of a event in which you had a lot of fucking noise to deal with. 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] The second video puts the alarm sound in the left ear only, which tells me someone added it in later since a mic on that kind of video would just be a single omnidirectional mic
Luckily my cousin wasn't on that flight, she's a stewardess with SIA, and she changed from long haul flight to flights closer to home recently.
Most commercial aircraft have an impressive glide slope.
All these news outlets saying the plane "fell 13,000ft" or "dropped 13,000ft" is just sensationalist bullshit. When an aircraft looses engine power, it doesn't just stop flying. Engines are not what keeps an aircraft in the air. Engines produce thrust, which is a needed and very much required force that modern airliners use to travel long distances by gaining and maintaining [B]altitude [I]and [/I]speed[/B]. If engines stall or become inoperable, then altitude and speed can no longer be gained [I]and [/I]maintained by using the engines. The combination of gaining [I]and [/I]maintain both altitude [I]and [/I] speed is basically the formula for modern day air travel. So, why doesn't the plane just start to drop, like a brick, to the earth when altitude or speed cannot be maintained? Aircraft wings are what keeps the airplane from falling straight down. They produce lift. Lift carries an aircraft on differential air pressure underneath each wing and stops the airplane plummeting straight down. Wings are fantastic things. Depending on their angle of attack (the angle that the air is colliding with the wing), they can be used to slow/speed up an aircraft and control a descent rate (and speed) very finely. They are amazing pieces of technology and modern wing design is just baffling how ludicrously fine tuned these bits of kit are. Using a wings lift as your primary force for staying aloft is a very fine balancing act - finding the right combination of altitude being lost against speed over the ground.This is called [I]gliding[/I], and a [I]glide ratio[/I] defines that figure. All aircraft have an [I]optimum glide ratio[/I] which the aircraft will loose the least altitude for the most ground covered. The aircrew on this flight knew this and assumed a glide ratio that gave them time enough to restart their engines. All aircrew are taught how to glide as part of their basic light aircraft training and all are familiar with the concepts. At no point did this aircraft "drop", "fall" or "plummet". It lost engine power, continued to fly, and regained engine power. Thanks to the aircrew on this aircraft, they flew the airplane first and foremost and restored engine power with no risk to passenger safety.
How do people not understand how aircraft work? They're made to glide through the air. Just because your engines shut off, does not mean you fall from the fucking sky. [editline]28th May 2015[/editline] [QUOTE=runtime;47823305]-Better Explanation-[/QUOTE] Yes.

[editline]28th May 2015[/editline] Yes.[/QUOTE] I guess it's because you can see, hear and sense the thrust produced by the engines whereas you can't see, hear or sense (if you've not got any flight training) lift produced by the wings. People don't like to trust in what they cannot see.

That's incredibly scary. Thanks for linking.
[QUOTE=cecilbdemodded;47822390]If they had been at 12,000 feet and dropped 13,000 feet then this would have been a more interesting story.[/QUOTE] Yeah if a plane tunneled 1000 feet underground, that certainly would have been a more interesting story. :v:
Should change the title so "plunges" says "glides" instead.
It's like planes in Southeast Asia are cursed or something.
