Weapon makers declare war on drones

Arms manufacturers are rushing to develop missile systems to take down drones. Arms makers are targeting the growing menace of drones at airports and on battlefields with a rush to develop new missile systems, radar jammers and laser cannons. U.S. forces, along with Middle East allies and Russian troops, have been forced to confront hostile drone operations. Commercial flights at some of the world's busiest hubs--in New York, London and Dubai--have been grounded in recent months amid concerns that nearby drones could endanger airliners. The rising number of incidents has put the threat in the public eye and propelled interest in anti-drone technology.
