Interesting. I was wondering something similar: if the Chinese, Iranians, Russians are paying close attention to the United States and any information that we might provide that might help them learn about our satellite tracking and other spy systems. Malaysia is right in their back yard.
It is possible that the US government knows the location of the plane but isn’t telling... not for a while, anyway.
I see the US Navy continues to brag it has it’s top intelligence aircraft working the missing plane. The P-8A which in realty I’m surprised it can find it’s way down the end of a runway let alone locate anything. If the US knew where the aircraft was or went down you can bet they’d be bragging this aircraft found it.. justification so to speak.
