We also haven't heard anything about cross referencing possible sat cell/regular cell phone owners (GPS origin) on the plane that may have tried to send out stealth signals or calls from the plane anywhere from take off to where ever what happened did happen.

Once the search is completed, attention is likely to turn to improving the tracking technology.

"It is hard for anyone to imagine that we can't continuously track aircraft anywhere in the world,".

There, the most expensive part of the process will not be the development or fitting of any technology, but the cost of getting it accepted and standardized by aviation regulators around the world.


most likely, any airplane that travels over water, & especially over international water,
- will be required to have some type of tracking device installed. ..

That will be the Main Outcome of this airplane disaster .. ..

Yup - it's only a matter of money to implement the world-wide wireless data network. The next question becomes how do you implement the aircraft equipment such that a fire, defective equipment, or a person can't disable it? One reporter the other day stated that we need to remove the circuit breakers so that pilots can't use them to disable the equipment. Nice thought - what happens if there is a short somewhere?

Plane had two onboard trackers that someone turned off... they didn't want to be found.... cheapest solution in the future will be to have a system that can't be turned off by the pilots...lucky for the searchers the engines...continued to beacon and could not be turned off by the crew...

News media has made the assumption that because two systems went dead in sequence a few minutes apart that someone must have purposely turned them off. I submit that if there were a fire that was burning through insulation in wiring harnesses it is quite possible that power wiring for one system burned through, shorted, and tripped it's circuit breaker. Some time a few minutes later the other system power wire burned through, shorted and tripped it's circuit breaker. The fact is at this time everyone is just guessing. No one has any evidence that pilots, crew, or anyone else manually turned off those systems.

Sad thing is some of the technology used on airliners is so antiquated it isn't funny. That airplane should have been able to be tracked to the exact point where it went down by GPS technology. Google can do a sat pic of your house, but the gov can't do a pic that is clear of a crash scene.

We are so far behind it is pitiful.

Thanks in part to the pilots' union rules, the flight crew can disable the transponders at will. If they were active throughout the entire flight, the plane's crash site would have been localized weeks earlier.

A short in the wiring doesn't make much sense, since the plane did a dramatic course change and took steps to evade detection.
