Quote from Mvic:
While I am no China apologist and recognize the very real danger of Chinese nationalism being used to keep stability and central control in the face of economic unrest we should also understand that it is not China flying spy planes up and down our coasts. The only time that a US navy jet and a Chinese plane will be in the same airspace is when we are just off their coast spying on them as we were in that instance. Can you imagine US reaction to "routine" surveliance missions up and down our coats lines, international airspace or not. Think Cuban Missle Crisis.

Good thing China does not spy on the US. Wait, haven't they been caught many times stealing US military technology? O well, so much for your theory
