Yes, there is a known reason, an aircraft would not be zigzagging, skilfully skirting ground radars. All sudden decompressions to date resulted in aircraft staying on its original programmed path.

OK, so please enlighten us why this aircraft was zigzagging through the airspace, flying straight then making turns.

Also, while you "twilight zoners" are googling. Look up the Helios accident and read about how smart people can do dumb things when hypoxic.
As far as changes to tracks go, is the wind constant over 7 hours of passage over the earth?

Manandasystem,
Read them all. Perhaps you can explain then? What are the pilots breathing via their masks once that cylinder ruptures?

Wind will never cause you to make a sharp 90 deg turn, and then another 100 deg, etc.. Clearly you don't fly because you would never use such silly argument. You also really have no clue how wind affects aircraft.

I fly the B777 and given all the facts provided by the officials a catastrophic depressurization is highly unlikely in my opinion.

In the scenario mentioned above if the depressurization was catastrophic crew intervention would have highly unlikely. In this phase of flight the aircraft would have been on autopilot in LNAV/VNAV modes. As such the aircraft if able to maintain flight would have continued on its programmed route. However the evidence provided so far suggests that the aircraft turned 180 degrees and made several course changes after.

Any of you so called experts actually received high altitude training in a pressure chamber, simulating a rapid depressurization? I have.

Of course it changed course. They selected heading, turned off the airway and passed out.

Lets look at some facts or evidences:

Plane was at IGARI when it lost contact
Oil rig worker saw explosion or sort off
Other 8 people heard of explosion
Oil slick found in east (But Malaysia denied that its Jet fuel)
US7 was one of the first to reach the area
Statements coming from White-house (US) and PM (Malaysia)
Selective leaks from Pentagon / White House
Chinese satellite picked-up something (one sortie by Malaysia plane - and they rule that out)
SAR stopped on east side of Malaysia
Vietnam accuses Malaysia of not sharing information
Only Malaysian primary radar has picked up the plane. Hard to believe that India, Indonesia and other neighboring countries failed to detect. Indian radars are quite capable and they deny any intrusion (statements coming from low level officers, not PM or chief of military)
No debris in Bay of Bengal or Indian ocean.

All information or data coming from Malaysia or US. So far Malaysia has been very inconsistent in revealing/sharing information. Vietnam and China says and proposes something, Malaysia quick to issue a denial to that.

Deduction

Malaysia is hiding something of great magnitude
US is party and supplementing to whatever Malaysia is saying or hiding
Something big has happened that Malaysia is trying to cover-up
All data/information related to satellite etc is false and is being deliberately fed as afterthought

Possibility
MH370 never flew west
It had a failure with its transponder (at a wrong time)
Crew trying to navigate
US7 fleet present in that area, picked up the aircraft on their radar. Edgy and trigger happy action by them or someone.

Deliberate action to cover-up and misguide everyone to look at west. While the clean-up is being done on east side.

There is certainly more to whatever is being said by Malaysia and US. It can be concluded that plane never flew west.

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?

No, Helios did not disappear because it remained on its flight planned track to a destination which happened to be a capital city.

The difference here, the aircraft drifted off in a heading mode.

Come on all you experts. When you practise an explosive decompression in the simulator, how do you manage the flight path? By programming a waypoint and selecting LNAV or by selecting HDG?

Porterhouse,
Really, Google Helios. Read what the cabin crew were seen doing in the cabin while the pilots were slumped at the controls.

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.

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,
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.
