U.S. Navy Laser Weapon Shoots Down Drones in Test

In a grainy, black-and-white video that looks like a home movie of a UFO attack a sleek aircraft streaks through the sky one minute, only to burst into flames the next and plummet into the sea.
The silent video, which Raytheon Co. debuts Monday at the U.K.'s Farnborough International Air Show 2010, however, is not science fiction. The defense contractor says it depicts part of a test conducted in May during which the U.S. Navy used a  solid-state laser to shoot down unmanned aerial vehicles over the Pacific Ocean.
