"Cabin collapse"
 
Collapse might not necessarily mean a structural collapse. In several other languages it could also mean "reduction" or "decompression".

Handshakes at 16:55 and 17:07 (Z) ??
 
If handshakes (other than 60 minute 'keep alive') are caused by course changes (beam reacquisition), why are there handshakes where there was no course change, and conversely, why would there be no handshakes between 17:21 and 18:25 where there were several major course changes??

Oldoberon,


wouldn't that 121.5 call be on tape at rayong.

Generally all ATC audio and Radar tapes are held for 30 days. Unless there is a specific request to hold them they are taped over and used again.

Propduffer 1st May 2014 03:32

@Datayq1
I've never seen it unequivocally stated that handshakes were caused by course changes. That still seems to be based on an assumption.

Luke SkyToddler 1st May 2014 03:57

I was also flying in the area at the time of the disappearance, I heard the SGN controllers and the MH088 trying to contact MH370 on 121.5 and I certainly didn't hear anything that resembled a coherent reply.

There's something in the SGN area which periodically causes 5-10 seconds bursts of buzzing static on all VHF frequencies. It's well known to all of us based out here, I'm pretty familiar with what it sounds like, and that's all I heard that night. Wish I had something more dramatic to report but I personally don't believe any transmissions were made on 121.5 from MH370 at that time.

and neither of these people would have reason to make up stories.
People do make up stories all the time so there is nothing unusual about it. It is enough to recall numerous "UFO reporting", TWA800 accident, etc. etc, this includes airline pilots as "witnesses". Specially when you can claim a "privileged" position and know something that nobody else does - it has always been a big magnet to exaggerate your stories.

I guess it's not real as a distress message on 121.5 would be investigated and recorded as evidence, you would hope.
I really find it difficult to accept that nobody on this planet knows or saw anything.

I really find it difficult to accept that nobody on this planet knows or saw anything.
Actually Inmarsat satellites "saw" much more that one could have ever dreamt of. I am amazed we know as much as we do, if it was a general aviation long range aircraft - there could have been practically next to nothing to latch onto.

BOING 1st May 2014 07:22

Let's face it, no one has the faintest idea were MH370 is. The present favorite hunch is based on a tolerably credible location based on the mathematical interpretation of a few isolated data points that even a political pollster would find inadequate. Come on Guys, show me a seat cushion, not a dozen reasons why you can't find one, you have been looking long enough to find something even though the search area is large.

As soon as you step back from the bustle and the numbers and ask the logical question "Why?", nothing about a Southern route makes sense in this situation. Why would anyone fly an aircraft towards the Antarctic? Does disappearing quietly make a statement? If you intend to crash an aircraft why wait 7 hours to do it? Why fly out of radar range heading Northwesterly then apparently turn Southerly if you intend to crash? Why would you head South when you could have achieved the same end by heading West or Southwest? How do you explain the actions of the flight crew, was one incapacitated, both incapacitated, hijacked?

Here is a simple question. If I intended to crash an aircraft in deep water why would I turn Westerly when I could turn Easterly and fly to the deepest water on the Earth in about the same flight time?

When I reach this illogical position in my own affairs I throw all of the paperwork in the garbage can and start afresh.

Datayq1,

Course corrections between 17:21 and 18:25 are toward the relative position of the satellite therefore there is no beam disconnect.


Something has to break the beam (the wing or crown of the aircraft, geographic features or another aircraft) for a reacquire to occur. A SATCOM communication from the aircraft will also cause a reacquire.

These two issues indeed also still give me some doubts if the plane is really where it is assumed to be at the moment.
On the other hand the INMARSAT data and the apparent pings received do strongly indicate it is.
But I agree in so far that it is strange really nothing of a 250t airliner has been found in almost two months. Not a single small piece.
Also the second issue has something to it: If you really, really wanted to disappear, why flying back so 'close' to the Australian shore, taking the risk of being seen by JORN. Why not flying South West, where you would be out of reach for any land based Radar and Patrol aircraft? Or immediately flying South East iso first flying over potentially Radar/Electronic Intelligence covered Terrain. It makes no sense at all if you wanted to disappear. There would have been even better Options.

However, If the plane is roughly in the area where they are searching (IMHO still very likely), they will find it and chances are, we will get an idea of what really happened. So let's simply wait and hope for the second Phase of the underwater search.

Here is a simple question. If I intended to crash an aircraft in deep water why would I turn Westerly when I could turn Easterly and fly to the deepest water on the Earth in about the same flight time?

1) Few or no countries to overfly post the first 1 hour of confusion
2) Little or no radar coverage once you swing west and then south
3) Little or no air traffic on that route except for a couple of EK flights
4) Total opposite direction to where one would look (if not for INMERSAT then search would have still been on in an easterly direction using the Helios thought process or at best in the BoB).
5) Little or no boat/sea traffic in that area
6) Flying in darkness throughout with a dawn water splash down
7) Well out of reach of most if not all countries SAR
8) Deep enough water

But most of all...............250 tons of metal still remain hidden almost 50 days later even with a proximate location......so if it went South then it seems to be hidden well enough with no debris showing up.....

What reason would they have for not wanting it found?
To make sure family picked up the life assurance payment. Often these exclude suicide, especially (IME) if you do it within 1 year of starting the policy.

IIRC the underwater pings were being picked up, at one stage, for a couple of hours, and that must exclude any possibility of a spurious signal, surely? There would also be a gradual change in frequency (unless the source is crystal derived) which the manufacturer could reproduce with end of life batteries in a test unit. And if the frequency is crystal controlled then it would be ultra stable long-term which would be hugely obvious over 2 hours (a few ppm long term variation) and the approx 7000 pings collected.

Georesonance press release

Georesonance press release
So now their "technology" involves quantum physics, as well as "invisible" parts of the EM spectrum somehow embedded in those satellite images and nuclear reactors and twitching twigs and everything. And of course they don't want publicity, that's why they've just put out a press release. :ugh:

MH370 Tragedy: Preliminary report - Latest - New Straits Times

Sheep Guts 1st May 2014 13:13

The report states twice that HCM control lost radar contact at Bitod. Interesting....

threemiles 1st May 2014 13:21

I would not give to much on that. IGARI and BITOD are quite close together.

Whats going to start now for sure is dirty laundrying ...

Eg: I find it remarkable that MAS OPS had delayed the necessary actions by using a public flight tracker (FR24 or Flightaware or Radarbox) with enabled position prediction capability and was reporting as last position a bit southeast of Danang. This was assumed to be in Cambodian airspace (!!) though.

So much confusion!

Carjockey 1st May 2014 13:24

Preliminary report
 

At 01:38 MYT HCMATCC made a query to KLATCC on the whereabouts of MH 370. Thereafter KLATCC initiated efforts involving MAS OPS Center, Singapore ACC, Hong Kong ACC and Phnom Penh ACC to establish the location of MH 370. No contact had been established by any ATC units and thus the Rescue Coordination Centre (RCC) was activated at 05:30 MYT.
The above is quoted from the NST report at MH370 Tragedy: Preliminary report - Latest - New Straits Times

According to this report 3hrs 52mins elapsed before big alarm bells started ringing.

What is the justification for this delay?

Teddy Robinson 1st May 2014 13:52

Regarding the press release
 
If Geo-whatever are so convinced that their info is credible, why are they asking somebody else to put an ROV in the water to prove or disprove their assertion ?
It would indeed be a major breakthrough is they had found the wreckage, but one has to wonder that given the prospect of a global headline hitting success story, they don't put their own money where their proverbial mouth is and fund an ROV to examine the site they have identified.

The press release was smoke and mirrors.
