SEPANG, Malaysia — Malaysia Airlines Flight 370 experienced significant changes in altitude after it lost contact with ground control, and altered its course more than once as if still under the command of a pilot, American officials and others familiar with the investigation said Friday.
Radar signals recorded by the Malaysian military appear to show the missing airliner climbing to 45,000 feet, above the approved altitude limit for a Boeing 777-200, soon after it disappeared from civilian radar and made a sharp turn to the west, according to a preliminary assessment by a person familiar with the data.

The key is those two Iranians..Im not a betting person but I dont believe for one second those two were seeking asylum. I dont believe it and I never believed it
People do make mistakes. This might have been one of them.

Smackdown. Sorry, but when some doubts or makes comments that are blatantly not correct without first looking up the facts, specially about something i do and am fluent in, it does drive me a little crazy.
Technical name is: Chemical Oxygen Generators. Its a chemical when ignited creates oxygen. I am sure maintenance engineers might know of a way, but the only switch for these masks is to DROP them. There is no switch to prevent them from dropping. They automatically drop when the cabin altitude reaches a certain point. Usually 14,000 feet. Is a pressurized mechanism that controls them
I am not guessing, i am not giving an opinion. I am trying to tell you. I have been flying commercially for 30 years. I am trying to tell you something. You refuse to believe or listen. Look up smartcockpit.com general and emergency equipment will tell you all about it.
Look up Chemical Oxygen Generators at wikipedia it will explain how they work.
Thank you. Somebody gets it!
Undoubtedly. Sure it "can" be done. First, not a good idea to announce to the world you busted limitations. Secondly, corporate jets are not Commercial jets. I flew corporate 7 years before moving into commercial airlines. Dont try and compare the two. Third, i am currently and have flown last 9 years in southeast asia. I am pretty sure i know the ISA temps around here. With any kind of fuel and payload, you are not going to even reach your service ceiling.
In fact thinking about it, this is the hottest period of time in the southeast asia. I have not even come close to being able to fly at my service ceiling past two months.
I now have no doubt. In my mind that if in fact it reached 45,000 feet, it stalled immediately.
More importantly, the attitude "i have done it before" will kill you in this industry. As a safety officer, investigating incidents that never make the news, that attitude was the basis of many many incidents.
I recalled the phrase “time of useful consciousness” from my aviation survival training at PAX. The “ride” in the hypobaric chamber with live practice with oxygen masks was an unforgettable experience. The pure oxygen sucks a vacuum in your inner ear over the space of hours after use.
The idea that the airplane was flown to higher altitude to disable the passengers is beyond silliness. It would demonstrate the perpetrator is not really all that smart or aware of the available options
And i am still confused, did all this supposedly occur ( changes in altitude) before or after the transponder stopped working. If after, how do they know the altitudes? If the data is coming from another source Like flight tracker, then that opens a whole new series of questions.
If it occurred before the transponder stopped working, then there are many other plausible options aside from a land shark coming up and biting them

Supposedly, Interpol spoke with Iran about the two Iranians, and that is how it was decided they are/were just poor, misunderstood asylum seekers, or something.
It seems to me that there is a lot of discussion about the altitude variation of the missing 777 without any verification of how the Malaysian military made that determination. A land based radar would only get primary returns over the ocean out to about 250 miles (maybe) but the radar would only show position, not altitude. Altitude is reported via the transponder, which was supposedly turned off. So how did the military determine the aircraft altitude? A ship based radar might have some chance of estimating altitude from a position near the aircraft, but even that’s doubtful. So, how credible is the assertion of the Malaysian military absent any qualifying information?
If I’m off base on this, someone please set me straight.
I have no idea. Does the following help answer that?
Because the plane stopped transmitting its position about 40 minutes after takeoff, military radar recorded only an unidentified blip moving through Malaysian airspace. (...) That is in part because the data is based on signals recorded by two radar stations, at the Royal Malaysian Air Force’s Butterworth base on the peninsula’s west coast, near Penang, and at Kota Bharu, on the northeast coast. Two radars tracking a contact can significantly increase the reliability of the readings.
Still, Ravi Madavaram, an aerospace engineer at the consulting firm Frost & Sullivan, based in Kuala Lumpur, said the accuracy of ground-based radars in determining a plane’s altitude diminishes the farther away the plane is. When Flight 370 lost contact with ground controllers, it was more than 100 miles from Kota Bharu and 200 miles from Butterworth, distances that he said could degrade accuracy. But the altitudes measured as the plane crossed the peninsula would be more reliable, he said.
The article describes the sequence of events.
That jerk should confine himself to investigating layers on OCD’ed documents.
iirc, there was a flight engineer (mechanic?) on board bound for a job in Bejing. Perhaps he was known to one of the pilots as an employee and they kept him alive for a while. Just a theory.
I suppose they may have worked and then been depleted - I wonder if pilot O2 runs off same supply.
When I “busted limitations”, it was with a FAA POI in the right seat and a FAA DER kneeling in the floor between us watching.
Notice that the "two routes" are in the same arc which forms a circle. This is likely because at the center of the circle is where the gyosyncronous satellite associated with "tracking" the aircraft (i.e., receiving the "pings") is located Or, actually hundreds of miles above that point, to be accurate. The arc is the limit of receptivity, so that what they are trying to say is that the last pinging came from within that circle, not that the aircraft went on one of two routes that form perfect arcs.
Erin Burnett is the only thing worth watching on CNN, she appears to be an honest journalist. I try to watch her when I can which is not very often. And she’s very easy on the eyes too.
Yeah I was actually quite surprised at what a good job she has been doing..imagine that, someone actually credible on CNN
