PBS session on the Ghosts of Machu Picchu

I saw this PBS special the other day called the Ghosts of Machu Pichu. It was a cool historical and anthropological look at why this palace in the Andes existed, and what happened to it. Side note, scientist type people can now tell what type of food people used to eat by vaporizing their bones. Remember to support PBS.

PBS's The Bombing of Germany

This link goes to the PBS video player and shows a look at the Allied bombing campaign against Germany during WWII. It covers the bombing of civilians and the morals(?) of war.
