Inmarsat data released
It seems that Inmarsat raw data was released:

I am sure you are familiar with Helios. In Helios, the pilots and most or all of the passengers were unconscious or dead due to climbing to altitude without pressurizing the airplane. According to the interceptor jets observations, one cabin crew was still (barely) conscious and (unsuccessfully) trying to make radio contact or fly the airplane, which eventually ran out of fuel and crashed.
(...)
In case the cause of the MH370 disappearance was defect in the pressurization system similar to what was experienced by Helios Airways 522, we would still need to explain the sudden change in direction over the Gulf of Thailand. If the scenario was exactly the same, I would expect that MH370 had continued its flight toward Beijing.

However, the pax system didn't fail so they make it alive and well to 10K feet, where O2 is no longer needed, and only then a pax took control of the plane, making the north-western turn along the Strait of Malacca and then South into the Indian Ocean. Not said buit implied, then the pax climbed again to cruise altitude (thus enabling the plane to fly so far and for so long before running out of fuel), and now yes, everyone perished due to hypoxia.
As I've said, I find this chain of events extremely unlikely, but not enough to completely discard it, since probably whatever happened to this plane would have been considered highly unlikely too.
But a pilot's murdercide fits very well the few known facts so far, and it's much simpler, so for me by now remains the first candidate. Heard of Occam's razor?

In a rapid decompression scenario however, after donning the masks, typically the first action of the crew is to set the autopilot for rapid descent to 10,000ft. They should have had the time to do that even if the masks malfunctioned. But there was no rapid descent. So it doesn't fit.
I am not gifted enough to be able to fill in all the blanks. But perhaps some small structural failure (or explosion or bomb) presumably somewhere near or below the cockpit, that caused some significant damage (failure of the ACARS, transponder and possibly the pilots' oxygen system) but still allowed the plane to keep flying.
But all this plus a failure of both oxygen masks and the auxilliary...?
Unlikely? Sure.

The US Navy has moved to dismiss comments from one of its officials who said pings thought to have come from MH370's black box were probably emitted by the search ship itself. Earlier today the US Navy's deputy director of ocean engineering, Michael Dean, said there was widespread belief the pings came from some other man-made source. However, another US Navy spokesman has told the ABC it is "premature and speculative" to suggest the pings are not from the jet's black boxes.
And now the US Navy backtracks on what they first said about the ping dismissal.
These guys are doing as well as the original investigators and are providing more and more ammo for the conspiracy theorists
Would ONE AGENCY please take control of this situation - it'd be a hell of a lot easier on all involved
I esp. feel for those who have lost loved ones and are hearing 'stories' from various 'authorities' none of which seem to have a clue

Yesterday afternoon, Bluefin-21 completed its last mission searching the remaining areas in the vicinity of the acoustic signals detected in early April by the Towed Pinger Locator deployed from ADV Ocean Shield, within its depth operating limits.
The data collected on yesterday's mission has been analysed. As a result, the Joint Agency Coordination Centre can advise that no signs of aircraft debris have been found by the Autonomous Underwater Vehicle since it joined the search effort.
Since Bluefin-21 has been involved in the search, it has scoured over 850 square kilometres of the ocean floor looking for signs of the missing aircraft.
The Australian Transport Safety Bureau (ATSB) has advised that the search in the vicinity of the acoustic detections can now be considered complete and in its professional judgement, the area can now be discounted as the final resting place of MH370.

I also find it hard to believe that three ping detections from three different sources in the same general vicinity can be attributed to natural phenomena or electrical interference.

Originally posted by Peter Kesternich View PostIf I have read and understood the discussion of cabin pressure loss on this thread so far, there is no such thing as "stealth decompression". Regardless of whether the pressure drops suddenly or slowly, as soon as the cabin altitude climbs through a preset value, there is an alert and the masks deploy.
But Peter, there is such a thing and the key word there is 'scenario'. Yes, the horn sounded warning Helios' crew of the cabin altitude, but they mistook it for a malfunctioning configuration warning, perhaps because they had some trouble with that recently. Scenarios usually involve factors like this that inhibit situational awareness. The masks do not 'deploy' in the cockpit so they continued climbing. They did report a problem with the A/C but quickly succumbed to hypoxia before they could identify the pressurization switch being left in manual (Helios ground center asked them to check this, but it did not register at that point). It only took 8 minutes from the warning horn sounding to loss of cognitive functions.
So there you go, stealth decompression scenario (ok, stealth pressurization failure scenario actually, the cabin actually never pressurized).
