The above youtube adventures got me searching on chinese air force stuff. I'd heard of the J-10 before, but any clues on the 'F-22' type creation in the first seconds of this video? Looks like its all photoshoped, though the "in hangar" shot with panels open / red covers on looks like quite a convincing prototype....
