12:40 -depart KLIA
1.22 -Fail to chk in with HCM
2:41 -Subang ATC 'lost contact'
ATC will exercise all possible contact options before they declare a distress phase. That is the most probable reason for the delay.

My bad re old news!.

The cockpit fire scenario ? How long would the plane fly on with all electrics disabled, Cockpit crew incapacitated or deceased?

Before this post goes into another 50 replies cycle as it already did twice on this thread:
Loss of transponder signal at 1:21 (closer to 1:22)
Subang center INFORMED MAS on loss of contact at 2:40 (2:41 by some sources)

In the intervening 1 hour 20 minutes both Sebang and HCM were trying to make contact with the aircraft. Only when the aircraft did not appear in range of Vietnamese primary radar was the alarm raised. Loss of transponder signal and communications happens on a daily basis somewhere in the world, with the aircraft usually appearing further down it's flight path and the crew mumbling a faint sorry to ATC.

In all fairness, SAR action should have commenced no later than 01:37. It wasn't just a Comms failure, they disappeared off the screen!

Time-line is not right"


HCM is on the same time as BKK/CGK, which is one hour BEHIND KUL/HKG/SIN time. These times could be LOCAL, which would make the time lines very different.

Ahhh, yes, the famous Glock radio-invisible plastic stealth gun. As a point of fact, a Glock contains a great deal of metal and is readily identifiable on x-rays as exaclty that; a handgun. And it has more than enough metal to activate a magnetometer.
Without agreeing or disagreeing with the inference
I presume he was referring to this....

Re: the times

I've just watched the main BBC News this morning. Roving BBC reporter just fresh out of press conference in KL. Quote: "........the plane was 2 hours into its flight....". Doh!
How many hours since the flight and they still can't get it right?!

Re earlier reports of a yellow object being spotted.

Latest is that it is not connected to the current search.

BBC radio 08:55.

Sorry if I raised anyone's hopes. I rather hoped it would be a positive sighting.

Nearby countries all seeming to be sending assets to assist. Hope they don't trip over each other, especially in this sensitive maritime area. Even Taiwan is sending vessels to assist.

Hard to believe a plane would turn to dust at high altitude (as someone previously suggested ) with anything short of a nuclear explosion. And for sure one of those would NOT have gone undetected. So that basically rules out that theory.

They just need to expand their search area. Especially if the plane was hijacked and flown at low levels for hundreds of miles over water.

As I cannot read the last page I can only guess this has not been reported.


BBC radio 4 has just reported that the " life raft?" spotted is nothing to do with the MH aircraft.

Malaysian Airlines MH370 contact lost

A fairly good "round-up" of the situation by Reuters press agency :

SAR

New information dated 1520 local (UTC+7 i.e. 0820Z) says a Vietnamese search vessel HQ637 has identified a "cable roll cover" or "mossy fiber roll lid" at the position where a suspected "liferaft" or "emergency slide" was earlier sighted.

So yet another false indication. Search continues...

source: Dan Tri via Google Translate

edit: apparently same info as beamender99's 5 minutes ago

edit2: new update but very hard to make sense of. We'll see...

A side note re: sliderafts. The B777 operator I fly for has silver colored sliderafts. It's the CANOPY which gives an orange/red color. This is separate to the slideraft and is to be installed by the crew for use on water (for obvious reasons) Anyone's know if MAS are different?

IIRC the only rafts I've ever used which themselves were yellow were those carried on B738 or supplemental carried in cabin on paxseats as part of overwater operations for aircraft normally limited to closer to land...

ETA: Evenrude's pic confirms same

As you can see they are pretty stinking big when inflated, certainly larger than the "door"-like object spotted earlier (which to me looked more like the plastic lav surround than a 777 door)

Logical considerations.......

Where is the plane? Without other evidence found, on the ocean floor.
How many pieces is it in? At least two, to facilitate it sinking.
Is the fuselage still intact? Substantially, yes, as typical floating debris such as clothing, cushions, life jackets may still be contained in the largely intact closed on impact cargo compartments and cabin areas.
Are the wings intact? No evidence of fuel slick found.
Why were there no communications made? Instant G load and rapid decompression.
Could the tail section have departed company?

One mystery PAX IDd

KL Insp General of Police says one of the users of a stolen passport has been identified.

I gathered wreckage from 182.


07.14 GMT at alt of 9,400 m, 190km off Irish coast. First wreckage discovered same day 09.13GMT. Even though it broke up in cruise, large pieces were quickly located floating on the surface and days later washed up on beaches.

Even Taiwan is sending vessels to assist.
So now every nation with a "South China Sea" claim is involved. I'm not surprised. Vietnam, Malaysia, Philippines, China, Taiwan plus interested third parties - US, Australia, Singapore(?)

As I mentioned before, I wonder who is the On Scene Commander? Who is co-ordinating the search effort?

The Reuters link didn't work for me. Here is another: http://www.reuters.com/article/2014/...A2701720140310

Surfcat's estimate using the simple schoolboy physics equation:

"On the freefall time, the 3+ minute estimate is a bit off.

s=ut + 0.5at^2, assuming an initial vertical velocity of 0, and initial height s=8000m (I can't be bothered to convert 35,000' to m), t would be around 40s."

Is going to be a huge underestimate since air resistance is not taken into account. So the original estimate may well be not far off but for a debris field with large variation in the sizes of the pieces then there will be a range of descent times and pieces will hit the surface over an extended period of time over several minutes.

So, let's apply Ochams razor... "the simplest theory is usually correct".

1. An inflight loss of control/structual failure.
2. A deliberate vertical descent into the ground/ocean.
