You mean like how China's first lunar satellite Changhe-1 required little to no course corrections on its journey there because China's calculations were so precise?
Journalist Ted Koppel has been for the last several years been trying to get permission to do a documentary on the Chinese military but they have yet given him permission and access. And that was when he was working for the Discovery Channel. He's not working there anymore so I have no idea if he's still pursuing it.
Well "Ted Koppel" is actually Alfred C. Neumann from MAD Magazine, so they are prolly just a little leery of that dude! AFB
