Boeing develops laser to shoot down planes from ground

Telegraph.co.uk - US military develops anti-aircraft laser

Boeing, contracted by the US government, has successfully tested a laser weapon that downs unmanned aerial vehicles (UAVs); UAVs are typically difficult for conventional weapons to target, being small and made from plastic rather than metal.  It shoots a laser beam from a humvee on the ground.  As UAVs become more prevalent because of their surveillance and tactical advantages, this weapon will become more useful.
