LOOK, UP IN THE SKY Concerned about remote-controlled drones flying freely around U.S. airspace? You're in good company. Congress last year directed the Federal Aviation Administration to allow drones widespread access by September 2015, but federal officials are now saying that such access will take significantly longer. For the forseeable future, drone use will be limited to permits granted by the FAA, which is still discussing a bevy of concerns about drone aircraft. There are a host of security and safety concerns, including whether drones would be able to avoid other aircraft and the possibility that remote-controlled drones could have their navigation controls hacked. And those issues don't even address the major concern:?privacy. FAA officials say they are working to address all concerns over drones, which is why widespread permits won't be happening any time soon. That's a good thing. There may be reasonable, limited uses of drones, including law enforcement, but there simply aren't enough regulations in place yet to help alleviate concerns over privacy and other issues.
