This has caused many many debates on a nightshift with the engineers at my work, namely how the aircraft stopped sending any engine data back to the company or manufacturer. The minute our aircraft have issues with systems or engines our engineering control Know about it and I think we use the same system

I saw the same report.  But I don't understand how that shows intentional suicide/murder.   It seems to me that a gradual water landing suggests not only that someone who knew what he was doing was flying the plane, but also that he was trying to accomplish a successful water landing.  It would make more sense to me as a suicide/murder if the aircraft went nose-down at high speed into the water.

I don’t think it shows anything other than someone who knew how to fly was at the controls either. Murder, suicide, saving everybody...who knows?

Extremely interesting read. I don't know enough and too untutored to give a valid assessment, but seems to make a strong case, supported by what little direct evidence there is.

Kind regards,

Personally I don't like the theory of one of the pilots taking control of the plane and crashing it deliberately, although it certainly can't be discounted...

I read somewhere that another theory was, that a fire in the electrical heating system should have weakened the integrity in the windshield, which then shattered, killing one of the pilots and (perhaps) wounding the other. The remaining pilot would then try to divert the aircraft - thereby turning it, but wounds and/or continuous electrical failures or surges, could have resulted in a catastrophic fire. Smoke could have then lead to death or incapacity of the remaining pilot and also rapidly damaging the remaining systems. 

This is - like anything else - just a theory. But it sounded interesting. There's no way we'll know exactly what happened, until when (or if) the wreckage and black-boxes is found. But I have a feeling, that it won't be found...

I agree anders that the uncontrollable fire is possibility.  I thought this until i spoke to numerous engineers at my airline.

I could be wrong here as im not an engineer but the way the aircraft sends the engine data is a on a different system than the transponder and to switch  the data off its quite hard, as well as a couple of circuit breakers you  have to manually turn something else off which isnt easy.  

I think these systems went down in tandem with the transponder, too much of a coincidence.  Like I said I know nothing about engineering but all of 15 to 20 guys in my IOCC in engineering are convinced it was suicide because of this reason, that captain somehow managed to turn it off.

On a side note to demonstrate this aircraft data information transfer ,  2 weeks ago one of our old 747s kept having "no land 3"  warnings coming up at all different stages of flight,  first of all it was flying on a DMI/MEL for it then it was AOG when we had to put a new console in it to stop the fault.  Every time it came up it pinged back to out IOCC the fault , this was in the in cruise, on finals, on taxi , you name it , it was coming up.  The engineering team for 48 hours as it crossed the pond twice continually had this sent to them WIITHIN SECONDS and an acars from the crew confirmed it.  This was over the mid atlantic going both ways.   Theres no way that Malaysian stop sending any data just like that, on a whim and  then kept on flying.

I called this with my post on Avsim way back during the first few weeks after the crash, when evidence emerged that the aircraft disappeared exactly at the airspace boundary between Malaysia (or Singapore?) and Vietnam, during the very short ATC handover period. The 777 is a very reliable machine and to have a massive catastrophic failure in that short 5 to 30 second window is highly improbable, to the point of impossibility. A catastrophic failure would have to cut the transponder, cut the radios, kill the pilots and cabin crew, but leave the autopilot working for many hours, and make turns on its own to waypoints that reasonable pilots wouldn't have entered in the FMC CDU flight plan page.

Discuss all you want with technical failure scenarios, but having the transponder turned off when switching comms between KL (Shouldn't they be talking to Singapore instead? It's their FIR) and Saigon ATC is simply too convenient for any sudden failure. I mean how long does it take to switch frequencies on the comm panel and start talking again? 30 seconds max? The 777 is simply too reliable and this smacks of deliberate action. If someone wanted MH370 to disappear, this would be the time to do it.

Another post from back then.

If the person responsible doesn't want MH370 to be found, then most likely it will never, ever be found. Not even debris. MH370 will probably become the modern day Amelia Earhart.

My guess back then was that to completely vanish, the person responsible would preferably go to the Southern Indian Ocean while staying away from the Diego Garcia and Perth military radars, or go to the South Pacific between New Zealand and South America, which is so remote that it is used as a spacecraft junkyard. he/she would also want to put the airplane down beyond the range of land-based maritime patrol aircraft, because AFAIK there ain't any Americans on board for the US Navy to bother dispatching a carrier task force for an expensive search operation. However I was a bit surprised with the satellite pings that the aircraft didn't keep changing course (using lat/long waypoints) after the turn south, so as to end at around the midpoint between Australia and South Africa/Mauritius.

And you should take into account data from the captain's own flightsim rig in the final Australian report, the keywords are "Southern Indian Ocean" and "exhausted its fuel".

A very interesting link, Jim. Thanks for posting it.

I believe that question arose early in the investigation, and it turned out that Malaysia Airlines had no contract for real-time engine monitoring (or aircraft system monitoring). It’s not a free service once the airframe / engines have passed their initial warranty period. Monthly subscription charges for real-time engine parameter tracking can be substantial, and some airlines opt out to save costs.

It wasn’t as case that the engines “stopped” sending data. They never did in the first place.

Last thing you'd want to think about ever happening...

I saw the video last night, thanks for the link, I watched all of it.  The only thing disturbing about this was the fact that, if a murder suicide, there appears to be no trace of a manifesto, or someone taking credit for this tragedy happening.  You would think that if the pilot or copilot or both were responsible, that they would have wanted to make some type of, any type of statement for their actions.  Which leaves the dreaded and hanging question, is the Malaysian government covering something up?  I think the answer at this point is yes....
