Soldato
I recommend anyone here to watch this. A slow peaceful flight from the Yellow river to the Gobi desert, no commentary, occasional music, many excellent educational captions, along the Ming Dynasty wall from one end to the other, across mountains and all sorts of interesting terrain. You see the wall in different forms and structures beyond the typical images we've seen, with some breathtaking scenery and even areas you can hardly believe people still live in. It's incredible to think that over various dynasties, the complete length of the wall was over 13,000 miles.
