It’s a big sky…until two planes end up in the same place, at the same time.  37,000 feet above the Amazon, a corporate jet collides with a 737.  A mile above New York City, a DC-8 tears into the fuselage of a Lockheed Constellation.  Using incredibly realistic HD animation and rare crash footage, we show you what happens when two planes are on a collision course. Apr.23.2013
