No sign or sounds of terrorism in cockpit recording from AirAsia QZ8501

"The voice from the cockpit does not show any sign of a terrorist attack. It is only the pilot, sounding very busy," Andreas Hananto, an investigator at Indonesia's National Transportation Safety Committee, said in an interview with the news agency Reuters.

He said Monday that investigators had heard "no threats" in the recordings.

"We didn't hear any voice of other persons other than the pilots," Nurcahyo Utomo, another investigator, told Reuters.

But it remains a mystery what brought down the aircraft on December 28 as it flew from the Indonesian city of Surabaya toward Singapore with 162 people on board.

Indonesia’s National Transportation Safety Committee are experts in scrubbing the tapes

Really?

I don’t think that terrorism was involved, but given CNN’s almost laughable reporting and lack of expertise in virtually any subject, I’d just pass this by and see what transpires after non-journalists (translation: those who have real educations) process the clues.

[technically right]

Other news sources are now saying that the aircraft suddenly climbed at a rate of 6,000 fpm. At 37,000 feet this would have induced a stall which the crew was evidently unable to recover from.

Sounds quite similar to the Air France Flight 447 crash in 2009.

no it doesn;t...Flying while Muslim happens often!

So maybe the Airbus software has a nasty bug in it?

[technically right]

I suspect the crew disconnected the auto pilot in order to initiate a rapid climb. My guess is that they were attempting to avoid weather at the last minute. They had requested an altitude change to avoid weather but ATC had denied the request due to congestion at the higher altitude. They probably hit some nasty stuff, said to hell with it and reefed back on the controls. At that altitude there’s only a few knots difference between going transonic and stalling. A 6,000 fps nose up climb would most certainly have stalled the aircraft.

This is looking like pitot freeze up.
The air trapped in the system expands with altitude, effectively fooling the autopilot that an over-speed has occurred, and commands a climb to reduce speed. That only causes the trapped air to falsely shows a additional speed increase, thus commanding more pitch up.
Finally the Autopilot gives up, and disengage.
Leaving the pilot hauling back on the yolk to reduce the false over-speed.
The angle of attack is so large the they get an engine compressor stall and the airplane,yaws into the dead engine, with a swept back wing then stalls and the plane enters a flat spin, possibly on its back.

It happened before , have a look at “Birgenair Flight 301”
( and that was a Boeing )
