Couple of interesting airports around. Have a look at kangding and yushu batang. Both are many miles from the towns they service, with little around. Yushu batang also has an old disused airport only a few kilometres east of the newer one, might be possible to land there without attracting too much attention. Of course it would be very difficult to hide from the next passing satellite.

Wasn't the crew oxygen bottle serviced recently? A slow leak, oxygen build up, and then an arc in the electrical bay setting it off could lead to an intense but short duration fire or explosion that breaches the hull. Those small ARINC 429 cables carrying ACARS and other data would be first to go. (When those cables go, you can not tune the VHF or HF as the control heads are ARINC 429 connected, so no communication is possible.) Minutes later, the transponder cables burn possibly.

During the fire and hull rupture, the crew is trying to figure out what happened, turning back to base as they enter hypoxia. Fire goes out, the tough T7 flys on to the Indian Ocean.

if you have a decompression, priority is to get on oxygen, then initiate an emergency descent to a safe altitude and the last action of the memory item sequence is to turn off the airway.

They selected heading, turned off the airway and passed out.
And they woke up 45 min later changed another heading and passed out again. And again. How many childish stories do you have in store for us? Do you have clue what kind of rubbish you are spouting?
There is no VERIFIED evidence of these subsequent course changes.


FWIW, I am a qualified pilot (DHC6 not jets) (retired) and also a qualified radio engineer so I am probably better qualified to debunk the stupid theories than some around here.

Hi Mr. Steak,
OK, so please enlighten us why this aircraft was zigzagging through the airspace, flying straight then making turns.
Until some one proves it had LNAV and VNAV command, and hit the waypoints and then did Rate 1's to the new track, I suggest that it was wandering.
Why, if a hypoxic pilot tries to enter a track back to KL but does looses consciouness half way through, depending where he is up to, there won't be any LNAV or VNAV.

Hypoxia will have you pressing the same button, repeating a small segment of a scan or repeating a checklist line, etc, until you drop off, and you will not be aware of it.

Whoever is in command of the investigation does have far more information than they are providing the press with.

If they were able to give us arcs for the last ping, they can do the same for all the other pings. By tracing those arcs, using satellite timestamps to calculate the time between each ping, wind data and calculated GS, it shouldn't be that difficult to calculate several possible routes for the aircraft, and then "precise" search areas...

I'm just a poor ground ops specialist, I suppose they have far better people working on it, but if I came out with that possibility, why wouldn't they? So yes, I suppose they have a good idea of the areas where to look...

There are VERIFIED heading changes, at least 4, but you don't like it, I understand, with about 200 nm straight flying between those heading changes. Don't make me laugh about your "radio" qualifications, are your there on the ground in Malaysia? If your are such experts who can tell from 8000 miles what's going on your expertise is missed by the world.

All of a sudden we have experts one with with 13,000 "commands" another a "radio engineer" and DC6. I am speechless, I am just a lowly PPL.

The Wawa Zone:

If the airplane was in heading select on autopilot it would have maintained this heading until flame out. If with wandering you imply the autopilot was off it would have crashed after a short while without any pilot intervention.

Or the crew were disabled (via innocent or not so Innocent scenarios) and some poor clueless innocent individual was desperately trying to gain some sort of control via MCP twiddling, a/c soldiered along until fuel exhaustion way out in the Ocean.

Why do these (in)denials remind me of SilkAir 185?

Someone, pax or crew took the plane. A loud noise is not an Explosion.
Planes flying along other airways is not out of control.

What are the underwriters doing?

Drama from this 20-20 hindsight & A dog /pony show hides the truth.
Governments take time to do anything (DMV?)
Why? pilot wants to become an Airheart?
Pilot wants to boost his early retirement?
Pilot is an islamic mole?
Pilot opened the door to the wrong skirt?
Lawn dart or bus to nowhere? Your call.

WRONG.
The heading changes are reported but not verified. I suggest that you go back and read what few real facts that we have.

And why are you being so agressive, cool it and chill out.

Given the 50/50 odds from the Inmarsat ping, there is the possibility that Uighurs and/or sympathisers had taken over and directed the a/c to some remote strip / landable area with the view to conduct a hostage negotiation with the Chinese regime.

Setting up military radars in the Himalayas looks to be quite a challenge. And likely one could fly below.

Avoiding CFIT would be a serious challenge.

Aircraft have been lost in the Andes above treeline, sometimes for decades. Survivors of one wreck were stuck for weeks until a party succeeded in walking out.

Obviously all parties involved in the investigation have far more information and resources available then any of the posters here. If they came to a high probability conclusion what could have happened to the flight, I am sure that this is the most probable outcome. I can't believe how much nonsense is posted here and the arrogance of some posters thinking they know more then anyone involved in the investigation.

It seems that the pieces are slowly emerging to form a fairly coherent explanation.

Perhaps sadly, this doesn't surprise me. A few of us were suggesting this days ago, but kept getting deleted. Sadly I and perhaps a few others here have seen true evil and know what people can do.

A few here seem to be struggling with what we are learning, and are determined to stick with inexplicable "explanations"

Incidentally, you can be sure the authorities are monitoring this thread. There is always a long shot someone here might come up with something from left field they haven't though of. Also if there were any co-conspirators, there is a fair chance they will be watching. Plenty of arsonists are apprehended watching the fire. I don't believe there are any co-conspirators and belief this was a lone wolf. But you never know.

First off, those who aren't PROFESSIONAL PILOTS should keep their insane theories to a minimum. I myself am a retired pilot who flew with a major airline for 32 years.

But look, airlines these days... some days I'd walk out the cockpit and it looked like a prison riot had taken place. I'm talking cups everywhere, graffiti, and seat-backs which had been slashed with knives somehow. Ridiculous. Trying to get a cup of coffee without lipstick on the rim of the cup was impossible, and that was when the stewardesses weren't busy cooking whatever it is they thought they were cooking. And I can't count the number of times I had to go back and settle some beef between a flight crew member and a passenger, lest we have someone trying to open an emergency exit at 30,000 ft.

Point being it's obvious that something happened with the pilots, but lets not libel them by delving into their psychology without taking all of this into account. The the poor guys up front just might not have been able to stand the smell of the plane, and theres only so many times you can take being told that the lady in 23F wants a pillow while you're navigating mountains in a fog.

Northern or Southern arc ? By now, using earlier arcs and knowing the speed range out of the last primary fix near IGREX, the RCC should have calculated that one.

So, are SAR assets being deployed to the southern Indian Ocean, or not ??

Another question ! Did the aircraft actually fly through the VAMPI - GIVAL wpts and track out along the published routes, or were those wpts given as approxiamations of some wandering track ? That answer would infer a lot about LNAV 'piloting' or 'wandering'. Also, is any RMAF AD radar VNAV info out there (?), ie., were the 90 degree+ turns at/near the waypoints painted at a constant altitude, or at the high points of some phugoid ? (and you know what that means..)

Sorry, got no information about suicidal alien remote control gold thieves
Just after the 1st maps of the arcs came out way back today within a few pages that question arose and the answer was if ACARS is shut down the selected transmitter (only vhf on this aircraft) would send a signal stating ACARS turned off, if it just died i assume it wouldn't, he/they (who ever was flying it) couldn't turn off VHF 10 min earlier as still had to sign off from KL.

ACARS turned off according to a recent post because it would have sent out a depressurisation message, and the theory is he wanted that done before stating the navigation manoeuvres. Makes good sense to me.

200 pages in and someone adds the new fact about the depressure message would go out on ACARS.

This is complete nonsense.

1. Daily Mail UK (enough said).
2. Backing PKR in Malaysia and being distraught over the jailing of Ibrahim is hardly "political fanatacism." The Anwar Ibrahim issue has a long history and to think the 18k+ hour pilot just somehow snapped all of a sudden is very unlikely. His assumed issues with the current political climate are COMMON in Malaysia.
3. Stop following drama and Hollywood style news.

"Avoiding CFIT would be a serious challenge."

Practicing in a sim might help.

GTC58,

If the airplane was in heading select on autopilot it would have maintained this heading until flame out. If with wandering you imply the autopilot was off it would have crashed after a short while without any pilot intervention.
If it went into the FL400+ level and had an upset event and recovered, I would suggest that someone was flying it at that point.
My point is that later, after failed attempts to enter a route back to WMKK or deciding in a debilitated state to hand fly it, the crew became unconscious and the aircraft was uncommanded.

As a 777 pilot, you appear to disagree that in this condition, given fuel burn and CG changes in flight, the dynamic stability of the aircraft would be sufficient allow it to remain in the air. How long would it have lasted, do you think ?
