China seems confident enough in its SU-27 knock-off to start showing it more publicly. To this day I remember expose after expose about how the then top-of-the-line F-14 and F-15 were just too damned big to be any threat to small, nimble USSR designs. As I recall, 60 Minutes and 20/20 were particularly aggressive about it.

Boy, I sure am glad we all listened to them and dumped those bloated cows, eh?
