Probably bandwidth. The site has quite a few hundred visitors right now. Try again if you are interested.
a few fanboy photoshop / fantasy drawings of nonexistent “5th generation” stealth fighter (and the fanboy arts aren't even consistent from pic to pic)
the “H-10” stealth bomber (a atretched version of the B-2) that's a prop from the movie “Broken Arrow” (featuring the nonexistent B-3),
a few stock photos of Russian import SU-27, the local copy of the SU-27 (J-11), SU-30MMK,
the new J-10 (built upon the Israeli Lavi),
various old MIG-21 based platforms - J-7, JA-7, FBC-1, planes that the PLAAF didn't even want for themselves (like airforce everywhere, they prefer newer hardware)but were forced to take a few so China can export the plane to Pakistan
old MIG-19 (yes, MIG-19 that's 50 y.o. design) based A-5.
old Soviet TU-16 based H-6.
J-8 II, a stretched version of the MIG-21 that was developed with help from, believe it or not, Northrop Grumman back in the mid-80’s (under project Peace Pearl), and that's a PLAN plane, not PLAAF.
Maybe the new WZ-10 attack helicopter.
Old WZ-9 attack helicopter which are essentially converted French / Italian Augusta light duty passenger helicopter.
Some old Soviet era Mi heavy lift choppers.
good ole’ American made Blackhawks we sold to China back in the mid-80’s, funny how China hasn't made a copy of it.
looks like two or three of the four AWAC prototype under development (although I think two were already lost to accidents) built on Soviet Anatov platforms.
various old Soviet AN light duty cargo planes converted to maritime patrol and ECM warfare.
not much there really ....
