51sec. Dropped a blade.

Cowling did it's job (containment) but looks to have let go a little more than expected in the vibration

It must be so confusing. Don't forget these people also have to find time to

1. Grab the seatback controller

2. Find and reach into their wallet for the correct credit card

3. Find the "Access the inflight internet authorization page"

4. Swipe said credit card and input PIN

5. Accept said terms after parting with your US$8 (that you previously saw no need for)

6. Wait for acceptance from online provider

7. Enter access code and click OK

8. Select FaceBook

9. Select Facebook Live streaming

10. Try to start streaming before you land

11. Become a HERO on American Cable News!

Meanwhile .................. the pilots, a couple of brave rescuers and two trained medical people jump into action. I know which side of the fence I would prefer to aspire to.

Maybe it did, but there's a missing window and plenty of damage to the wing there. Interesting (from an armchair observer POV) when only one turbine blade detached.

The damage to that leading edge flap would have worried me if I'd been on that plane, more than the missing engine bits.  Wondering what was going to happen when it was deployed.

A pre recorded message does play in the cabin once masks drop.

 

Presumably that's video as well as audio? Because audio isn't going to work well at FL340. Especially with a window out.

Theres a few slo-mo videos about with what *should* happen when a blade detaches or any sort of ingestion. And the amount of alloy and armour plating-like walls it has to get through to be outside and cause damage like that tends to be infrequent. Not to sound like it was downplaying with the damage that DID occur, but the key is the inside bits are contained (they make more of a mess when the come outside.. think 8ft skillsaw). Pretty sure the plan is to minimise cabin damage while being survivable. And although the shrapnel took out a window and control surfaces....

This is what happens when it doesn't make a mess.. you can see where I get the idea it shook it to bits. https://youtu.be/JKlIR-nzE6I?t=23

Well this is a little concerning. And also familiar..

Many folks mock and scoff at the airline safety messages and many ignore them. After all these years of jet travel this is a prime example why we have them and why one should watch them

This is all just another media beat up and it shows how ignorant and ill informed the media are.

Let's imagine for a moment that we know nothing at all about how these masks work and how oxygen is delivered to passengers in a decompression incident.

How many passengers died from lack of oxygen on this flight? How many passed out? How many showed even mild symptoms of hypoxia?

The answer is none. Surely that should tell us all that there was no big deal with the way that passengers were using the oxygen masks?

How can that be? Why did they not all pass out or worse?

Here is the big secret, if you are at the top of cruise - say 39000 feet - you can put one of these masks on over your mouth, keep your mouth closed and breath through your nose and you will still be OK.

How can that be?

The mask is not designed to replace all of the air that you breath. Even if you put the mask over your mouth and nose, most of what you inhale will still be cabin air sucked in around the edges of the mask.

The mask is just adding a little extra oxygen to the mix. Enough to keep you well.

So what would happen if you put the mask over your mouth and breathed only through your nose?

That little trickle of additional oxygen would come out of the cup of the mask and get into the air surrounding your face.

Then you breath in through your nose and you suck in most of that extra oxygen anyway.

You will certainly suck in enough to keep you going,

That is why the captain chose to land with minimum flaps deployed (5 degrees on the trailing edge and none on the leading edge). It meant a higher airspeed over the threshold but was safer than choosing normal landing flaps and wondering what would happen to the LE flaps. In the photos, you can see that the LE flaps are deployed but that was because after roll out, full flaps were selected as, in the event of an emergency evacuation, fully deployed trailing edge flaps form part of the over-wing evac path on a 737.

Similar thing happened to an AirNZ 767-200 out of Brisbane about 16 years ago. (My father was the Captain).

A bit different however, as it wasn't the blades that broke, but the axel which linked the 2 fans together. The front blade section came out of the engine and took out the leading edge flaps.

Fun times!

I was going to say if the video was anything like Air New Zealand's 5 minute long advert then no one would have watched the cringe fest anyway..

but having flown southwest 2 weeks ago I can tell you they still do the watch the hostie put the masks somewhere in the general area of her face...Don't touch the makeup!... 

I much prefer the 45 second: belts, mask, exit,  tray table go!   than the New Zealand stop reading we are going to show you some stupid actor you have never heard of touring Antarctica, a couple of all blacks, and use so many local colloquialisms that foreigners are guaranteed to have no idea what we are talking about for the next 5 to 6 minutes

Don't see why there couldn't be an automated recording playing when the masks drop telling you to place it over your nose and mouth?

 

Because the attention is on what's going on or has happened. You can be lucky if you afford to 1. help yourself and immediately 2. help others with the oxygen masks. In 30.000 ft you won't have the chance to understand and hear the end of the automatic announcement ... alive. That's why safety rules are demonstrated BEFORE the flight.

kiwiharry: Which case could they have been advised to keep masks on over their mouths only?

There is no advisory like that. To recover with pure oxygen from altitude hypoxia you should keep the mask over mouth and nose as long as the oxygen from the chemical generator lasts. Emergency descent has to happen to FL100 (or the safe altitude) at maximum operating speed (when the A/C has no structural damage) with engines on idle. The time of useful conciousness is about 1-3 minutes in FL300, in best case.

If there is no oxygen anymore after an emergency descent, you (all) will remove your (their) mask surely by your(them)self. A typical OXY GEN lasts 12-20 minutes, depending of the manufacturer.
