Remember, Boeing has satellite data monitoring of it’s engineered componentry it offers as a service. Although Malaysian Airlines did not subscribe to the service – the capability to activate the tracing systems within the componentry still exists without registration and payment for the service.
Think of it like owning a GM vehicle equipped with OnStar. OnStar provides a tracking service to tell you, among other things, when your car needs service or maintenance, and can diagnose routine issues (oil, air pressure, engine operation, transmission, fluid levels) remotely. They can even connect your monitoring to notifications toward your chosen mechanic service who will contact you based on the data received by the OnStar service.
If you do not subscribe to the service, the capability to “switch on” the service still resides with OnStar at any time. They can activate the tracking and monitoring without you knowing it.
Boeing could “activate” the same monitoring of their Rolls Royce engines and componentry at any time – regardless of whether or not Malaysian Airlines subscribed as a customer. Potentially, this is what has taken place. Boeing may have “tuned in” to the MH-370 engine signal broadcast as a means to locate it. Hence they report its location in Pakistan.
The removal of U.S. military ships in the ongoing search would not be done if the U.S. held reasonable probability they would find MH-370 at sea.
The Israeli military would not be preparing so readily and openly if their intelligence reports were leaning toward the plane as crashed.
