NASA's newly released video archives contain a skyfull of goodies

NASA is forever linked to space, a plucky government agency bravely hurtling people and robots into the great beyond. Yet the agency has always had as much of an earth-bound mission as an outer space one. The "Aeronautics" at NASA may get short shrift, but with 300 videos of archival aviation tests released online this week, there's plenty of airborne excitement waiting for viewers. There are drop tests of the X-1, the first plane to break the speed of sound in level flight.
