bicycle discovered constructed entirely from wood: proves metal not required for transportation http://www.leevalley.com/newsletters/woodworking/2/3/article1-1

  We already knew that because we have had wooden boats, carts, and planes (gliders).

    You're missing the point—this is the single greatest discovery in exobicyclology since E.T.!

      Tee-hee - it's true that these NASA announcements are often a bit of an anticlimax, but I suppose that's the price of having so much science-fiction to enjoy. Oddly enough,the first bicycles were actually made out of wood - they were called velocipedes and today we call them balance bikes. Like scooters, they were powered by pushing feet along the ground. I was going to link to an amusing site about these, but while looking it up I was surprised to discover that there are in fact modern bicycles mostly made from wood, although they're quite expensive: http://www.renovobikes.com/ http://www.renovobikes.com/ ...so I wasn't as well well-informed as I thought I was.
