'Contact lost' with Malaysia Airlines plane

No.

Air is supplied to the air conditioning packs from the engine. You wouldn't need to climb. You could just turn off the packs or manually open the outflow valve and raise cabin altitude. Turning off the packs and opening the outflow valve would be fast. The cabin altitude would raise, the masks would drop and the passengers would get about 15 minutes air from the drop downs. (Those that bothered dropping). At a cabin altitude of less than 25,000 feet no one on that plane would be conscious.

Why would you even bother doing that, you are locked in no one can get to you if you are going to kill everyone on board you don't need to make them pass out and die. You just point it at the floor. The only person he would need to subdue would be the other pilot/s unless they planned it together.

Also, from what I have heard, there isn't anyway to manually turn off the cabin pressurisation in a 777 if you are at altitude.

I doubt that. I'm not 777 rated but have other boeing ratings. You just flick off auto and go to manual pressurisation and manually control the outflow valve. Or turn off the cabin pressure controllers by pulling a couple of easy to reach CB's.

It's how Helios happened, the pressurisation was in manual and the crew were incompetent.
 
There were 20 employees from the same electronics weapons company on board the plane. Not really sure if that has any bearing on anything. But then, no one has any bearing on the plane either....OMGLOL AMIRITE

Unofficial Unconfirmed
XX:XX New York Times reckons that whilst near waypoint IGARI the radar says it went up to 45,000 feet :eek: and then descended unevenly to 23,000 feet.

Yeah, the higher altitude would have made better use of the fuel.

The fact that the thing was still up there at 8.11am is completely insane. The rest of the crew and passengers must have been subdued somehow to prevent them from mutineering.

If it flew along one of the main flight paths up around India wouldn't other planes have been able to see it with their radars?

It's possible dozens of 'planes' saw it and millions of people on the ground but if nobody knew it was missing then it would just be another plane in the sky.
By the time it was missing it could have been anywhere.
 
What are the chances that it was landed and refuelled? Meaning it could be quite literally anywhere by now.

Wherever the hell is it, whoever flew it has had a week - a week - to cover their tracks. That's a hell of a long time.

I think we're pretty much ruling out any kind of structural or electronic failure by now.

It couldn't get to 45,000 ft. Already been debunked.
Thrust not sufficient
wing doesn't have enough lift
Carrying too much weight
 
Fascinating all this though isn't it, no one here has a clue what's gone on, pretty sure people in places know however, they've known since it started to turn the wrong way for sure.
 
We still don't know how much fuel was on board. They obviously give them more fuel than their flights require in case of diverts or problems but would they fuel it to the brim? If we knew that we would know the max destination it could've reached although it could've circled for hours and not actually gotten much further than the last marker.

Edit: Although as Housey said above, what we know and what the people that need to know know is probably completely different.

I just think it's petrifying how a modern airliner with a capacity of 200+ people - with no-one on board who can be suspected of terrorism - and no signs of structural failure - just disappears and can't be traced even a week later.

If it can happen to this flight, it can happen to any. The only mainstream theory I can think of is that the captain was in on it.

I don't see what's to stop it landing and being refuelled if it was on a corridor to Kazakhstan.

Refuelling & taking off again complicates matters far too much, some one has gone to a lot of effort to make this aircraft dissapear, but i think refuelling & taking off again would be just too risky from a surveillance point of view.

If government agencies didn't know imagine the amount of background work they would have to do. Every single person on that plane would have to have their houses searched, their Internet and phone records would have to be recovered and searched, their families would have to be talked to and friends of the families... :eek:

Edit: And that's without questioning anybody and everybody who's ever had contact with the plane.

It might yet come to that.

What I've read on PPRUNE:

The book time for that journey is 5 hours 21 minutes. When it went missing it had been flying for 39mins of that journey, and presumably had the engines on burning fuel whilst taxing on the ground for about 15mins before hand.
The authorities say that it when it disappeared it had fuel left for a further 7 hours 30 minutes of flight at normal altitude (but that if they dropped altitude it would be less fuel efficient).

That's over 8 hours of fuel loaded in the tanks... for what should be 5 hours 21 minutes flight?
<Tin-foil hat mode>Is that the normal amount of safety-cautious reserves for emergency diversions/weather avoidance? Or did the Captain request more fuel because he's got a plan?
 
I think most people want this to have a happy ending but it's getting to the point where anything other than a completely unbelievable story and outcome will now be a massive disappointment. It's like we're all following one of the most intriguing spy novels ever written yet it's happening in real life.
