Really? Giving lessons on taking off/landing on short runways - lessons that could be applied to air operations on an aircraft carrier, constutute state secrets? He hasn't denied teaching pilots this stuff, though he claims he never knowingly taught Chinese airforce pilots. He also taught tight formation aerial exhibition flying, which again could have military applications.

From what I can tell, that's the main thing he's accused of. There's been no accusations of weapons or combat training, actually landing on aircraft carriers etc. As I read it all, I thought "that's it?" He's also accused of sending money abroad in some sort of laundering thing, but I can't see how the US military would care about that enough to extradite him.

They might have more charges once he's in US hands, but from what I've seen in the indictment documents, people could probably learn that stuff in Australia.
