Have there been examples where we see them uncovered? I'm not sure if I've seen that but never really noticed a coloured glassy cover on J-20. Could this indicate that this is just how it is and the equipment can emit/receive past the cover material? I don't know if they still have optical sensors and I won't pretend to know how DAS works.
No one here owns the photos. You’ll have to trace the photos back to their original sources on the Chinese military forums.Very Good Photo. Can I use the photos to do an interactive infographic on the J-20? I mention the owners of the photos at the bottom of the page. I would also like to involve you in the project, and I post it here on the forum.
Ciao from Italy.

Pretty much anything would be better than the 2016 show. Two fly down the runway, one flies off, the remaining aircraft does a few turns, flies away.I hope they pull some tighter turns for the actual show. This practice routine looks slow and conservative. Don't see why they wouldn't show off J-20 a little if the plane is able to perform. Notice no afterburner used in the practice run.
