media - rocket scientists recall the cultural revolution

Dealing with the more painful moments of China's past is not one of its media's strong points, to put it mildly. So, I was pleasantly surprised when bumbed into a very well done documentary on CCTV-9 on the history of its adventures in space.
Older scientists sat down and told how they tried to pull the program through that 'messy' period, we know as the Cultural Revolution (1966-1976). They told how colleagues were beaten by the crazy crowds and they were all scared into political action.
There were great scenes from 1970 when China launched successfully their first satellite into space that broadcasted the revolutionary song "The East Is Red", convincing even the most staunch Red Gards the space program was a good thing.
Nothing shocking and new for the outside world, but good to see Chinese academics talk rather relaxed about this sensitive part of China's past.
