Air NZ passengers aboard flight NZ414 experienced a dramatic period this morning as the aircraft lost cabin pressure for reasons yet to be announced by the airline, the loss of cabin pressure in flight caused the oxygen masks to automatically deploy in the cabin. Its good know know that they are all okay.

Interesting.
Of course the plane pictured in the article that you linked is a 787...sheesh...gotta love the media!

Has a couple of photos, presumably from Twitter.

It says they dropped to 7000 feet, anyone know how high they were before depressurization?

Michael Donaldson, a passenger on the plane, a Boeing 737, which left Wellington at 7.30am, said about 15 minutes before it was to start landing procedures the oxygen masks dropped from the panels and a continuous "this is an emergency" was played over the PA system.

Donaldson said the plane then went into a "very steep" descent which lasted for about five minutes before it levelled out again.

Argh... First, the PA announcement says "this is an emergency descent", not just "this is an emergency". That both takes away some of the drama from the first paragraph and also fully explains the second.

Doesn't sound like much of an event. Obviously some of the passengers were unnecessarily scared (they probably wouldn't have been if they'd actually listened to the safety briefing that specifically talks about the procedures in the event of a loss of cabin pressure). But somewhere around the world a scheduled flight loses pressure pretty much every day; it is literally almost a daily occurrence.

What's the reg. # of the 733 that was involved?

You are trying to minimize the people's reaction. I have tested these systems in the air many times - and once it happened unexpected - and it was a surprise and a bit unsettling. So for these business travelers to think it was unsettling is understandable.
Having worked with and for several airlines around the world - I would say - it does not occur somewhere every day.

Iv flown for almost 13 years, Iv had one rubber jungle on a B747 which occurred accidentally after an inadvertent ring main oxygen issue and I can assure you it scared the bejaysus out of me the moment it happened and that's despite my in depth knowledge of events. And I'm sure if it happened again in the future it would be just as scary initially!

So it's not fair to slate people for being "ignorant" and hyping it up beyond what it is because quite frankly when you're in a metal tube full of fuel hurtling at a few hundred miles an hour at 40000FT, anything that seems out of the ordinary can seem terrifying!

I'm not "trying to", I am doing exactly that, with this particular passenger. Loss of cabin pressure is not unheard-of; the pilots train for it; the possibility of it and what to do in the event of it is explained in the safety briefing that passengers are supposed to listen to; the only emergency is the descent; and there was never any danger to the aircraft.

The linked article is actually a bit more balanced than many are, in that there are quotes from people that do say most of those things ("details" many news organizations leave out). But in this case the passenger being quoted is definitely overdramatizing - the "emergency descent" announcement is easy to hear and understand, and moreover it contextually makes perfect sense when you hear it (meaning it's not the kind of thing you'd hear and forget because it seems unrelated to what's going on), so he clearly just left the "descent" part out to make it sound more dramatic. Without the word "descent" it sounds like there's some unspecified emergency going on, rather than an emergency descent that's clearly to get down to more oxygen-rich air. There is no such announcement that "this is an emergency" - such an announcement would be completely pointless. The announcement says what it says because it's providing information to you that specifically tells you what's happening.

I'm the first to defend passengers who might react a certain way to real emergencies, but in this case you'd have to have ignored the safety briefing, intentionally misheard the repeated emergency descent announcements and failed basic high school science class to not know what was going on in this plane, and that there was no danger as long as you followed instructions. It's one thing to be nervous, it's another to panic.

You can't expect most passengers to take in fully the 90 seconds of info thrown at them in a safety demo! It's a lot to cover and generally rushed by the crew providing it. That is why safety demos are very particular in how they word and demonstrate things (eg bags do not inflate etc). They cover the very basics and do go into unnecessary detail! They certainly do not state that a decompression doesn't mean the plane is crashing etc! And your comment about failing "basic high school science" is ridiculous! Passengers AND CREW are very much entitled to feel fear and be disorientated by any unexpected and rapidly occurring incident such as a decompression...and for the record, Iv heard the decompression announcement at my airline, its not always so clear considering the cabin environment at the time of the occurrence!

I'm not trying to defend sensationalist journalism but I do suggest empathy towards those onboard!

Maybe in terms of international news - no, it's not. From the passenger point of view it sure as hell is. Not what you expect when you board, and probably not something that most of us will ever see while flying.

With all due respect, it's easy to dismiss this as unnecessary panic after the fact when it has all ended peacefully. But in those few seconds when it starts happening -- and you don't yet know how it's going to end -- most rational people are going to get a little irrational because they are scared out of their wits. Try to remember that those fortunately very rare incidents where the plane crashed and burned and everyone was killed may well have started out just like this. Stop lecturing people for reacting like human beings.

The main thing going through my head would not be it’s a decent it is what has caused the problem. Has part of the airframe failed or is it just a tech issue.
