If it was an oxygen problem, the flight crew have their own separate to the passengers, so they had time to send a mayday. Nothing was heard so that makes one wonder.
But as you say, until the flight recorders are recovered, it's all conjecture.

But Helios Airways Flight 522 didnt send a mayday.
They had a oxygen problem because a F16 fighter observed the pilots and was trying to communicate with them visually. They didnt react.
The pilots was reporting air conditioning problem 7 minutes after take off.
6 minutes later all contacts where lost
3 hours later the plane crashed.

True, but at least they were observed, with MH370, nothing was observed.

janneseti you are completely right on this . That plane went down because the pilots did not check the switch that turns the cabin pressure on . It had been turn'd off by a technician on the ground when he was doing a routine maintenance check . I the pilots did not check it as it was not in the check list i think as it should always be turn'd on and tech's are supposed to return the switch back to where it was before checking it AKA in the on position .

So did something like this happen

Also the O2 for the crew only lasts appox 15 mins enough to get the plane down under 10,000 feet

So the big problem with hypoxia is it creeps up on you and can overwhelm you before you realize what is happening .
Maybe the pilots just did not realize what was happening til it was to late to even put the O2 masks on

That aircraft is safely on the ground, under the control of ISIS, to be used in the future as an enormous cruise missile, filled with tons and tons of explosives, and in the worst of case even large quantities of radioactive material.(no, not a nuclear device, just a very very dirty bomb)

If ISIS can massacre thousands of innocent people in Syria and Iraq, have no doubt about what they did to the passengers and crew of that flight.

This is the scenario that scares me the most.

My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events.

That aircraft is safely on the ground, under the control of ISIS

On a rock in the southern Indian ocean that is big enough to land the plane on service it and have it take off again, but that rock is too small to be seen in any satellite photograph. I love it. :)

Bob all this talk about ISIS ..give me a break .

The only thing i have heard is the plane was landed on a airfield run by the US so unless ppl here are now seriously saying the U.S gov is in cahoots with ISIS then i think everyone needs to stop drinking or smoking or taken what ever pill you are and sober up a bit

I'm more inclined to think Hypoxia is a much better reason after all the pilot mite just have realized what was going on and turn'd the Auto pilot on but set it to the wrong direction as his last attempt to do the right thing before he passed out than ISIS having anything to do with it

Thanks for all the reply's.

Just want to add this.
Malaysia Airlines Flight 370

I can't help noticing that if you draw a line from the last record known place the plane was to where they think it is . and then draw a line from Beijing to Kuala Lumpur it looks like the auto pilot was travelling directly parallel to a return flight would have from Beijing to Kuala Lumpur only moved over to the left of where it would have flown so i'm starting to think Hypoxia and what i posted may just have happened .

The pilot relized at the last moment turned the auto pilot on and passed out .
If the auto pilot had not been reset after it had done a return flight back from Beijing then the compass heading would have still been on the old setting possibly .

Hence it would have keep flying in a south westerly direction till it ran out of fuel .

Unless finding the black box this is purely speculation.
From your link Lynn.http://www.nytimes.com/2014/06/27/world/asia/malaysia-airlines-flight-370.html
Because of an editing error, an article on June 27 about a report by Australian officials on the disappearance of Malaysia Airlines Flight 370 over the Indian Ocean in March misstated the conclusions of the report. It said the most likely scenario was that the plane’s crew had become incapacitated and listed as a possible cause hypoxia; it did not conclude that hypoxia was the cause.

Depressurization of an aircraft can occur from mechanical failure, an attempted hijacking or many other causes. If a plane undergoes gradual depressurization, pilots do not necessarily notice that they are losing oxygen, and with it, their mental clarity. Masks are supposed to deploy automatically with a loss of air pressure, but they need to be fitted properly for a full flow of oxygen.

Personally I find this very plausibel.
I has happened before.

Personally I find this very plausible.
It has happened before.

I'm with you janneseti

certainly is the most plausible thing so far i have herd

I wonder also why they cant design black boxes with some mechanism that releases the box when submerged and that can float.

Good question probably money !

Or a black box that releases some kind of coloring agent when it hits the water... A coloring agent that lasts long enough for rescue teams to find it.

Maybe both.
Since the box is thousands of meters under the surface and stuck to the plane it would be neat if the box could float.
Then a boat can follow the signal and pick it up:)

Simple ideas are usually the best.
But very hard to find.

True:) But as Glenn says, probably costs a lot:(

How much cost one tragic accident like this?
Safety comes first.

In april Reuters estimated that the search operation would cost $44 million. Its now august.

If i remember right Black boxes is a ozzy invention and i think they haven't changed much . I have a sneaky suspion that the reason they don't put these thing in them because of where they are stored on the plane and it mite make them to big and complicated
