haven't finished the video, but with my ragtag mandarin, it's about appreciating 2 people (scientist?) in the development of first indigenous heavy transport aircraft
and he did specifically mentioned about a roll out at 5th or 6th in Xian
the rest is about research progress and future research
they were talking about AVIC has two of its engineers newly elected to CHina Academy of Engineering.
The first scientists/engineer he talked about was from Xian, He was the cheif engineer on JH-7A program. a structures guy.
now he is the chief engineer on the "large transport".
and yes he talked about a roll out on Jan 5/6th 2012 at Xian. it is the biggest airplane china has built to date.
If this thing gets out the hangar there will be pictures.
I have been waiting for this thing
forever.
