For all the talk of pat downs and body scans, one thing is still amazing: We can fly! During my holiday travels, I caught myself in childlike wonder at the fact that thousands of times a day we send 450 ton metal tubes packed with people shooting into the sky. GE has been doing a series of videos on technology. Their Paths of Flight is darn breathtaking. Watch the choreography of all the planes that take off and land in a day. Wowza.
