Maxed Out on Everest
Hundreds of people are now attempting to climb Mt. Everest every year. National Geographic writer Mark Jenkins says the mountain, once tackled only by professional climbers, has become accessible to anyone who can afford to pay to go up and down. And as a result, the mountain is being ruined by garbage, human excrement, and even bodies of deceased climbers.
Also: In a World War II era blimp hangar in California, a prototype of a new kind of aircraft, the “Aeroscraft” is being tested. It’s a space-age looking machine that’s almost as big as a football field and able to carry 50 tons or more.
