CNN now reporting that U.S. Officials saying Lithium batteries could have brought down the plane. There are redundant methods of communication onboard, including a stand alone SAT phone. None of these methods were used. I do however believe there might have been a fire typr event that was brought under control or contained.

But whether they were enforced or not...

Those little green bastards are pissed that we've got redneck ATV's running all over their planet flipping over rocks and such so they decided to take down a plane.
Hey, it's an option and CNN will probably cover it in their neverending quest to be the first to be wrong in everything.

That's my theory. Just wait until some real and actual news about this is locked down: theories and speculation are useless. Just go for a walk, or go to sleep and have someone wake you when the mystery is solved.

(26,549 posts)Google "thermal runaway" if you want the gory details, but long-story-short, lithium batteries are stable because of the electronics controlling them. The battery has to be kept in a relatively narrow operating range to be safe. (Narrow compared to other rechargeable battery chemistries)
Something goes wrong with those electronics, and the battery can overheat. That causes the battery to burst and catch fire.
Note that "overheating" here is well beyond the temperature you'd reach in a hot car - you'd need an oven to overheat the battery without an electronic failure or a short.
So yes, it is possible for the battery to malfunction and catch fire in a car's trunk. But since you're on the ground, it's not that dangerous a situation - just stop the car and get away from the fire. Can't really do that on an airplane. So you need to have it as a carry on to avoid an accidental short. If the worst happens, having the battery in the passenger compartment lets the crew respond with fire extinguishers before it's a very big problem.
Btw, don't buy cheap Chinese replacement batteries. They use cheaper chemicals that are more likely to be a problem. They also use lower quality electronics to control the battery.
Wow. I just bought a cheap lithium replacement battery for my camcorder.

(26,549 posts)someone was awake and relatively nearby - You don't have to watch it charge, just be able to respond to the smoke if something does go wrong.
I actually know someone who's house burned down because they left the laptop plugged in while they were at work. The battery overcharged, burst, and caught fire. That lit the house on fire. Since no one was at home, the fire had engulfed a lot of the house by the time the neighbors noticed.
But the battery cost 1/10th what the OEM replacement battery cost.

By Simon Hradecky, created Tuesday, Jul 3rd 2012 19:59Z, last updated Tuesday, Jul 3rd 2012 19:59Z
An Emirates Boeing 777-300, registration A6-EGQ performing flight EK-308 from Dubai (United Arab Emirates) to Beijing (China) with 270 people on board, was enroute near Urumqi (China) when the crew received an aft cargo fire indication and activated the cargo fire suppression system. The crew diverted to Urumqi for a safe landing, emergency services found a number of burned bags in the aft cargo hold, the fire had been extinguished by the cargo fire suppression system in flight. No injuries occurred.
Urumqi airport reported a few pieces of luggage were damage by fire, a particular suitcase containing a lithium battery was identified as source of the fire, evidence suggests the lithium battery ignited as result of thermal runaway, the cause of the ignition however needs to be confirmed.
