Yet another video emerges of the Chengdu J-20 taxiing.
The filmer is using a much better quality camera than the one previously used. The black spot on the upper left suggests the camera is hidden, as does the sudden cut at the end.
A few more things strike me about the plane. Particularly the way the landing gear doors hang all the way down to the tarmac. Also, the massive thrust nozzles and great distance between the vertical stabilizers. For aficionados of exotic aircraft, this thing is the real deal.
Gotta find a way to get up to Chengdu.
