China is hiding a secret cell phone battery that lasts longer than 12 hours.

this whole situation is getting weird
.... official US investigators supposedly discovered engine data transmissions that suggest the plane was flying for several hours after disappearing from radar. Malaysia PM dismisses report as "inaccurate".
Not trying to propagate American exceptionalism heres, but the PM of a 3rd world country that obviously has no clue what it's doing with this search... is implying that a seemingly valid report from foreign investigators is inaccurate with no evidence supporting his case? Why the offhanded dismissal of findings that could be critical to the investigation?
Not saying the supposed findings are correct as I'm no aviation expert and not involved in the case, but these last few days reek of either blatant stupidity on behalf of Malaysian officials or there is something else going on.

that would be clear discrimination on your part.
most muslims are NOT high jackers or suicide bombers.
Yes. But 99.9% of suicide bombers are muslims.

Last time I checked Malaysia was not a 3rd world country.

I traveled there in 2009 and outside of Kuala Lumpur the place was no different than other southeast Asian countries in terms of general poverty/sanitation/etc. it's an emerging economy being close to Singapore/HK but the majority of the country is at least 3rd-world esque so I beg to differ on that one

Everyone is moving to Kuala Lumpur, especially the young people.
The US is poor, too, outside of the bigger cities. Ever been to rural midwest?

The flight data recorder can not be turned off by the flight crew. The flight data recorder does have an acoustic beacon detectable by sonar systems to aid in its recover.
Why would you make it possible to turn off the transponder? It seems like it should be something the crew can't turn off.

Thanks.
But I still don't get it. Why should the transponder be turned off, even by an accident or by electrical failure? Aren't there backup transponders? You can have tiny transponders like "SPOT" that use gps to send positional information all the time. Why wouldn't a plane have something more sophisticated?
How messed up is this?! Imagine being a family member of one of the passengers or crew and reading about these theories being published in the fringe, conspiracy-theory-laden Wall Street Journal, of all places!
From CNN:
The account has raised questions among some U.S. officials about whether the plane had been steered off course "with the intention of using it later for another purpose," the newspaper [WSJ] reported, citing a "person familiar with the matter."
The newspaper [WSJ] said it was unclear whether the aircraft had landed somewhere or had crashed.
no tin foil,
Are you are saying that new technology permits Chinese cell phones to hold a charge for over 120 hours and are keeping this technology from the US market?

Yes. But 99.9% of suicide bombers are muslims.
And 99% of bombers in the US have been Christians.

So the percentage of Muslim bombers is ten times higher than the percentage of Christian bombers. That's a pretty significant difference.

My phone holds a charge for 240 hours.

One of the features of ADS-B is situational awareness over an ad hoc network, that is that all users can see where other's position and velocity. Aircraft that are on the ground aren't particularly interesting to the situational picture and potentially contribute to operator overload so the transponder is turned off until takeoff. ADS-B is a relative newcomer to general aviation and will not be required by the US FAA until 2020.
Commercial aircraft do have backup systems including the secondary radar transponder (ATCRBS) that provides information for the benefit of air traffic control, but when queried by radar, typically when the aircraft is in controlled airspace, not throughout its flight.
There's also the ubiquitous radio transceiver whereby the flight crew can report status to whoever might be listening. Commercial aircraft have redundant navigation systems including at least GPS, inertial, barometric altitude, TACAN sensors, and looking out the window (or on radar) for land features.
Has the Payne Stewart case been getting mentioned as a possible comparison?
Definitely a Payne Stewart situation here, what's the range on a 777? Look in the North Pacific or unpopulated areas of Siberia.
How are asians so smart in the US but in their native countries, they can't fly planes? Look at that Korean jet that crash landed in san francisco last year because the co pilot didn't want to offend the pilot.

Good stuff again.
But on the internet I can at any time in the summer see where my uncle sails his boat. I can also follow my paragliding friends in real time with their SPOT devices. These things operate via gps satellites I guess. Why isn't there any gps info from the plane? I suppose a 200$ SPOT device could tell us where the plane flew. And couldn't even a single phone that was switched on be tracked by the phone companies? Criminals are routinely found guilty based on where their phones were at certain times.
Something smells here. I just don't know what.

But how does that scenario address the transponder being turned off, which to my understanding would have been done manually? Anyone know?
