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.

Pilot opened the door to the wrong skirt?
Lawn dart or bus to nowhere? Your call.

There are VERIFIED heading changes, at least 4, with about 200 nm straight flying between them. Don't make me laugh about your "radio" qualifications, are your there on the ground in Malaysia?
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.

Art Griego 16th Mar 2014 02:36

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.

The Wawa Zone 16th Mar 2014 02:41

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 ?

Has anybody asked what was in the cargo holds yet?
Yes, the Wall Street Journal. Quote:

The B777 has a super critical wing, as such it is not really designed to have aerodynamic inherent stability. Without pilot inputs it doesn't take very long for the aircraft to depart its altitude and flight path in manual flight.

cvr
 
CVR would record the last two or three odd hours... the initial part is overwritten... earlier they'd use a continuous tape, nowadays they use solid state devices...In the present context the CVR wouldn't have anything from the early part of the sortie...

While some, (though not all) CVRs can have their stored audio erased on the ground by the press of a button, this is not the case with the DFDR. The only way that the Flight Data Recorder's contents could be "wiped" would be to remove it from its mounting rack and physically destroy it, or hide it where it could not be found.

However... although there is as yet no hard evidence that one (or both) pilots went "rogue" , and deliberately engineered the disappearance of the aircraft, IF that does turn out to be the case, I'd be willing to bet a month's salary that both the CVR and DFDR were disabled very early on by pulling their respective circuit breakers - meaning that even if the aircraft is eventually found, (either intact or in small pieces), that the "black boxes" will contain absolutely no data whatsoever covering the critical stages of the final flight.

That scenario would require that the CVR and DFDR CBs be in a location readily accessible to the flight crew. I have no idea if this is the case with the 777, but on all of the business jets I maintain, (Hawkers, Gulfstreams, EMB-135 etc) the CBs for both the CVR and DFDR are located on the flight deck, within easy reach of the crew.

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.
Explosions/catastrophic failure at 39000 or even 25000 feet would leave a debris swath which would be miles long, with a large amount of it floating debris. Putting a transponder off is very easy without even accessing the CB panels. Once the transponder is off the ac is virtually a ghost aircraft.
Almost impossible to imagine India not picking up an aircraft of this size passing through its airspace.

ADS-B usually set on auto needs to be deliberately selected off with the FMC interface.

ACARS uses SATCOM as an alternate to VHF, but pinging doesn't happen randomly. To my limited knowledge it isnt like a modem pinging the server to 'keep alive'.

Giving credibility to some deliberate actions by individuals who have some vested interest.

The Ancient Geek said


The tiny amount of VERIFYABLE evidence simply tells us that something went badly wrong. Apply a good dose of Occams Razor and...
which you continue to explain as


...the simplest explanation is a catastrophic depressurisation, probably due to a structural issue. Cargo door, cockpit windshield, upper skin panel ...... many more possible. Even a birdstrike is possible - it has happened before at 37500 feet but I doubt if vultures would be flying at night.
...yet the pilot did nothing
- then this catastrophic event leads to the the ACARS going out ... and the pilots did nothing
- then Transponder fails ... and the pilots do nothing
- alarms are going off everywhere ... and the pilots do nothing
- next the pilots make their normal handover contact with ATC ... and tell them nothing
- at this point they pretty much instantly flip the plane around 180, but in the middle of it apparently ... pass out?
- now quick ascent ... pilots stay passed out
- this leads to stall and fall ... pilots stay passed out
- now maybe they wake up to avert the stall? ... must pass out again though
- next after about 20-30 mins they wake up and turn 90 degrees before ...passing out
- another maybe 5-10 mins pass I believe it was Godzilla comes in and blows he plane onto another course ... pilots still passed out
- another 20 mins, wake up and turn, then ... pass out again
- at this point maybe the plane has a straight enough pass to fly completely straight to crash site without being pinged by any countries radars ... pilots never woke up again

that is approximately what you call your "Occams Razor/simplest solution" (and some people actually agree with you here, amazingly)

...meanwhile ...

this is what some of the best minds in the Governments of seeming all Countries involved, as well as most experts and many people here (include mine):

- People who knew what they were doing did what they knew how to do

Wow, you know what - after typing it out, I can so totally see how our theory is just sooooo dang complicated and illogical and all that while yours is just so unbelievably simple!

... :ugh:

Thank you. 'The Ancient Geek' seems to be ignoring any data that does not agree with his chosen 'simplest' theory.

LASJayhawk 16th Mar 2014 03:41

JRBarrett: Can't swear on a 777 but on a NG737 all four flight recorder box breakers are in the cockpit (it gets power from both ac buses and both dc buses. CVR is in the cockpit as well. On the ACARS MU it has 2 breakers one on an ac buss and one on a dc buss. both on the flight deck as well.


It does seem like either the ACARS MU died at the worst possible time, or someone pulled the breakers.

The Wawa Zone 16th Mar 2014 03:45

Thanks, so therefore it's options for remaining in the air would be FMS commanded flight, or hand flying, and that it would be unable to rely on a third possibility of dynamic stability, to phugoid it's way along until fuel exhaustion or terrain impact at a low point of the amplitude.

Low roll stab will also indicate that the first divergences would occur in roll, and turning flight (or spiral flight) rather than more or less straight tracks would be the result. Would you agree ?
