Investigators Believe Plane Flew On for Total of Up to Five Hours
U.S. investigators suspect that Malaysia Airlines Flight 370 stayed in the air for up to four hours past the time it reached its last confirmed location, according to two people familiar with the details, raising the possibility that the plane could have flown on for hundreds of additional miles under conditions that remain murky.
The investigators believe the plane flew for a total of up to five hours, according to these people, based on analysis of signals sent by the Boeing 777's satellite-communication link designed to automatically transmit the status of certain onboard systems to the ground.
Throughout the roughly four hours after the jet dropped from civilian radar screens, these people said, the link operated in a kind of standby mode and sought to establish contact with a satellite or satellites. These transmissions did not include data, they said, but the periodic contacts indicate to investigators that the plane was still intact and believed to be flying.
Corrections & Amplifications U.S. investigators suspect Malaysia Airlines Flight 370 flew for hours past the time it reached its last confirmed location, based on an analysis of signals sent through the plane's satellite-communication link designed to automatically transmit the status of onboard systems, according to people familiar with the matter. An earlier version of this article incorrectly said investigators based their suspicions on signals from monitoring systems embedded in the plane's Rolls-Royce PLC engines and described that process.

U.S. Investigators Suspect Missing Malaysia Airlines Plane Flew On for Hours
Okay, this helps some. That bit about the engines transmitting for four more hours was denied early on by RR and Boeing but it still spread like wildfire.
This thing could well be on land somewhere. Note, I didn’t say it landed but simply that it could be ashore somewhere.
And there are records of unconfirmed blips from the other air radars in the area.
We had no assets in the area that recorded anything?
The key to this “mystery” is to find it, before it finds us.
I get the feeling there is MUCH more going on here than the Malaysian Government wants to say.
Not being said in the hyperbolic western press is that the government went after, and convicted, several opposition leaders on what many believe are trumped-up charges, from Sodomy to Sedition, in the last few months.
I read a report earlier that said there were only two 30-minute engine data transmissions - around take off and approaching cruising altitude.
Where is Columbo when we need him?
If they can determine which satellites and a time stamp, they should be able to deduce course direction.
That is exactly what Malaysian Airways has reported - there were two and only two data transmissions that they knew about - takeoff and cruise. They know of no others - the speculation is contagious.
Those engines don't transmit continuously - they transmit at significant events or every 30 minutes.
Not sure if there's a way to turn that off from the cockpit. If there is, then the hijacking theory still has legs.
If not, then there's no way to fly for 4+ more hours without that data being transmitted, and no reason (that I can see) for RR or Boeing or Malaysian Airways to cover it up.
that means nosedive or massive explosion.
They probably already have, but are not telling us because it would have global ramifications.............I R A N..........Hacked Drone..................sound familiar?
Imagine if the world found out that ALL 777 or similar aircraft could be electronically hijacked with no warning........
Investigators of the Payne Stewart incident never concluded the speed of the decompression - whether it was slow or rapid. A commercial airliner's oxygen systems are automatic and should deploy when the cabin pressure exceeds a certain altitude - something not required of private jets. They also deploy for the pilots. At 35,000' the time of useful consciousness is from 30 to 60 seconds.
A rapid decompression could reduce that by half, though, if air is forced out of the lungs due to the decompression - source: http://en.wikipedia.org/wiki/Time_of_useful_consciousness
That’s at least 3500 miles. Not bloody likely, considering they’d have to fly over India, who might notice.

Thanks for the info.I'm just speculating here, and will be the frst to admit I know very little about aviation. This whole situation is just very bizarre.
The FAA’s worldwide will probably have the ATC/ADS-B transponders and CPDLC locked down can’t be turned off by the crew, it will be almost impossible to steal a big airplane in the future.
Here is a link to the WSJ’s streaming coverage - very useful updates:
I think Boeing and Rolls Royce would categorically deny everything just in case their equipment was at fault. Lawsuits could cost them how much for all those passengers? In the billions?
I also recall that Greek airline accident about ten years ago when the cabin pressurization got set on "manual," and caused everybody on board to black out. Since the autopilot was set, the aircraft just continued to fly until it ran out of fuel and crashed. Of course in that case they were still able to track the plane.
i am beginning to believe someone stole it. explains no crash, no transponder. pity the folks on that plane.
That's pretty much my take on it; something catastrophic along those lines; obviously the most logical conclusion. They should be able to estimate where the wreckage is and do a thorough search and eventually find what's left. I have a feeling that there's some incompetence going on here; that people have looked in the right area, missed or overlooked things, and then concluded that they wouldn't have to search that area again.
If the airplane’s satellite link was working, why wasn’t the Rolls-Royce engine health monitor also working?
Not enough fuel?...........
Where is Tom Clancy I say? =)
Exactly..dead people can’t turn off transponders..and you have to be extremely knowledgeable about planes to do so, so the pilots(Or someone else, like a hijacker) had to have turned them off..remember, all of the 9/11 hijackers, the second they took control of those planes what is the first thing they did, turn OFF the transponders
Iran would be out of range and they already have access to large aircraft. It would have to be a smaller terrorist group with control over a remote airstrip large enough for a 777. Then they would need to be able to refuel it if they are going to use it as a weapon.
>> decompression ... happened, immediately killing everyone on board...
Well, it doesn’t “immediately kill”. TUC - time of useful consciousness is altitude dependent. At 35,000 feet, you can go from 30 to 60 seconds before you enter la-la land. A rapid decompression (i.e. a BIG hole in the fuselage) can cut that time in half. But still plenty of time to get over the “WTF was that?” and put on the mask.
FAA regulations require one pilot to wear the O2 mask above FL350 (35,000’). This is routinely ignored by aircrews.
So here is a what if scenario question.
If you wanted to bring down the entire airline industry and terrorize the global flying population for islamic terrorist purposes, why not hijack a redeye airliner, fly it westward under the cover of darkness, land it somewhere in an islamic country, and start beheading the passengers, one by one after several days? And start posting the videos on Youtube?
I know it sounds crazy but i just went through nineteen threads on the airliners.net forum and the fact that this was a redeye does not seem to get a lot of attention. The passengers would never know they were over a huge body of water of water in the dead of night. During the day people would start asking questions and raise hell.
The whole scenario of the 777 crashing somewhere does not jive with the transponder being turned off. I can’t help but think that we have an entire new terror scenario here.
Doubtful, from my view. If that system is causing a fire or electrical overload, you have to have the capability to shut it off. That’s why all these systems have off switches anyway... safety. Doesn’t matter if its the O2 system, if it is a risk to the safety of the aircraft, there has to be a know to disable it.
It’s a big world out there............................

Exactly UNLESS they were separate services. See post 25.
Added about 700 miles to the trip to Beijing. It’s about an 1.5 hours over the planned trip at cruise airspeed. But the plane took off, wasted an hour at least before heading west. If it dropped much below 30K, the planning data really cuts the range. Its 3200 miles to Iran.
I don't know much either, but have learned some from fellow Freepers in-the-know. You're absolutely correct, it is out there.
Just someone who was trained to do it. Don't even have to tell them why, just do it.
How deep is the deepest part of the Indian Ocean?

You are not familiar with FAA certification standards. I am type rated in several types of “private” jets and they all have automatic oxygen mask deployment. On the other hand, pilot’s oxygen masks do NOT deploy automatically. Pilot’s have quick donning oxygen masks.
At least the ADS-B should be locked down, forget the squawking.
Never been a pilot I'd guess. It is powered by the plane's electrical system, subject to fire, isolate so you have power for other systems.
Thank you for the correction.
Without any electronic contact in any way shape or form?

Right idea, wrong terms. The big hole would lead to an explosive decompression, not a rapid decompression.
Aircraft and engine manufacturers have own engineers working alongside with any airline’s maintenance sites as consultants or technical representatives. They have access to everything from ACARS data, on-board and maintenance diagnostics, etc., Mr. Hussein, the Malaysia transport minister, may not be aware of.
I’m afraid that false accusations, particularly of sodomy, have been SOP since Mahathir’s time.
