Cabin depressurization doesn't account for the fact that ACARS and the transponder were disabled, nor does it account for the multiple directional changes of the plane.
If you watch the "Effects of Hypoxia " video on YouTube you can see the confused state of a hypoxic pilot.
The transponder is a simple switch that could be accidentally turned off by a confused pilot slowly losing oxygen.
As far as ACARS I am getting conflicting stories about how it's turned off. Some say you have to climb into a 'pit' below the deck while some suggested it can be turned off from the cockpit?
The directional changes were due to the pre-programmed alternate route/auto-pilot.

On a Boeing 777 you have to climb below decks to turn ACARS off. That's why most Boeing 777 pilots who are interviewed on Fox or CNN are saying this was completely intentional.

It's a knob and you have to turn it to off.
and that would have been done way before ;ast contact with ground.
If one is suffering from Hypoxia so much that they turn the wrong knob on a vital piece of equipment, I doubt they would be alive 12 minutes later.
Top right is the two channel radio, two slots below it is the transponder.
bottom right of this image is the pressurization controls.

ACARS can't be manually shut off - you have to disable the circuit breakers in the avionics bay to preclude any transmission of data.
To do so would require calculation and intent.

the theory is it burnt up.

Of course it could have been the hypoxia making them do it...?

But would they be able to do it under the influence of hypoxia that severe? And would they still be alive 12 minutes later to talk to ATC?

If its sunrise there now, I imagine they are there searching. I doubt they waited for the sun to come up to leave.

No. I was being silly.

Just a little more information on the protocol required to effectively disable ACARS...

Turning off the radios and ACARS would be more difficult. NPR's Geoff Brumfiel spoke with commercial pilots, including two who have flown Boeing 777s similar to the jet that vanished with 239 people aboard.
He says the pilots tell him that those systems are "pretty hard-wired into a modern aircraft. "They said you'd have to go through big checklists, you'd have to possibly pull circuit breakers if you wanted to deactivate [all the communications equipment]," Brumfiel tells All Things Considered host Melissa Block.

Maybe not . Unless it was a slower depressurization rate on the 777 than in the controlled study . (I believe it was 6 minutes until they gave the guy oxygen. I think).
An overconfident pilot whose really not aware there is a major problem can perhaps ....
I'm going down swinging with hypoxia ,huh?
You always have great information. Are you a private pilot?

You're gonna have to apologize to me after the investigation(if anything is learned)
I'll bump this thread. At least I'm not convinced it's cloaking /black holes/ landing in a country like Pakistan ,etc....
Who knows Ben Padilla(airline mechanic) stole a Boeing 727 from a West African airport back in 2003. FBI & CIA investigating & 10 years later no one has ever heard from Padilla nor the 727 since.
How the hell does a man & a Boeing 727 just disappear off the face of the planet?

Obviously, this plane was deliberately taken over (hijacked) by someone. Hopefully one day we will understand the entire story and what happened.

Yes with a whopping 87 hours total flight time.
50 of that training..
I just keep very current and have read all the coursework up to ATP pilot. So I'm good on the ground stuff. Flying is just so expensive, I'd rather wait until I can actually purchase a Cessna (which I hope is in my forties) to really get into it. Maybe get my IFR.
(as I don't even have that). It's just so cost prohibitive to do all this if you have no plans to be a pilot as a career. I should have just got a sport pilot. But then I only like the bigger planes. I hate flying in a two seater. You are literally arm to arm with the person next to you in a tiny box.
It's fun though. Nothing better than sightseeing the coast or the bayous in a plane. And working out of class D and B airspace helped a lot with radio skills and patterns.
It could still be hypoxia. I actually hope for the pilots and passengers it was an accident.

Wrong. Just an accident. Something happened that took out communication. They turned back to line directly over big airport. Overcome and plane then straight lined until it ran out of gas.
Posted on 3/20/14 at 7:04 pm to biscuitsngravy
So if it was mechanical failure, why didn't the pilot take the plane to the closest airport?

The paths it was programmed to take do not take it anywhere close to approaching the patterns to the closest airports.
Unless it was lining up for Kota Bharu's army base near the coast.
But then the plane should of had the turn to enter pattern..
It's all speculation.
I'm kind of hoping for hypoxia now just because it's better than murder suicide for all involved.

An alternate flight route had already been programmed prior to the last verbal transaction with the plane.

Kinda crazy.
The guy had no idea he was hypoxic and wouldn't even put his mask on.

Flight schedule for today. It's crazy how far this location is from land. Even these long range aircraft are limited to 2 hours search time due to distance to get over it location.
