I feel like I probably watched this a billion times as a kid, driving my parents insane (I’d be surprised if they couldn’t recite the thing from memory).

The whole thing is posted on youtube so you too can enjoy (though I’m sure there are many better modern documentaries, if only for HD footage if nothing else). Still this is cool, I’ve always been fond of the segment through the Andes.
