Hearing on CNN that the 777 is outfitted with four emergency locator transmitters that are independently powered and activated in water. How is it possible that not one of the transmitters was activated? I would need one heck of a lot of proof that this plane is in water. IMO the current search is a waste of resources and $$ since it is focused in an area that is speculative. What absolute proof is there that this plane did not fly in another direction like North?
Thank You
Yes...Buuuuuuuut ( sorry there always seems to be a But)
Flight MH370: Emergency beacon mystery examined

“These beacons are equipped with their own batteries and shouldn’t be affected by any sort of power failure in the aircraft.
However, once they sink completely, the water blocks the signal transmission.
There were cases in the past when a helicopter or an airplane simply sank like a stone and the beacon didn’t have a chance to activate,” says Cermack, who has extensive experience with search and rescue operations
Beacons not always mandatory
Moreover, there are no set international regulations requiring all aircraft worldwide to be equipped with such a beacon, or Emergency Locator Transmitter. The guidance is fully in the hands of aviation authorities of individual countries.
According to the spokesman of Boeing UK, the lost Malaysian aircraft, a Boeing 777-2H6ER was delivered to Malaysia Airlines with four emergency locator transmitters back in 2002.
However, the company doesn’t have any information about whether the operator (Malaysia Airlines) made any upgrades to the system since.
It is not known which version of the Emergency Locator Transmitter was aboard flight MH370.

As of 2009, traditional 121.5 MHz ELTs are no longer monitored by satellite.
The system has been replaced by a far more powerful and robust system operating on 406 MHz. - See more at: http://www.acrartex.com/products/catalog/elts-general-aviation/#sthash.VuNng1q5.dpuf
