So we have been landing on the top of the dam. This is a sensitive strategic location because the consequences of the dam being breached would be catastrophic.

Mao didn't live to see the dam built. It wasn't finished and fully funciotnal until 2012Yangtze river.

  Look at that. It's an inland sea. Thirteen cities, hundreds of towns, hundreds of thousands of people were displaced to make way for this. This lake or the reservoir behind the dam stretches back almost the length of England.
