“Passenger Plane Barely Dodges Drone Above New York” cried a Time magazine headline earlier this year. How scary does that sound? And the reports of close calls between airliners and small drones keep coming. In 2013, 238 drone encounters were reported by pilots in the United States. By August of this year, that number had already hit 700. What’s behind this aerial mayhem? More and more drones, of course. One industry group says that we have already sold millions of small unmanned aircraft systems, while companies such as Amazon are lobbying government agencies to operate their own commercial fleets. The population of drones is predicted to grow 15-20 percent each year over the next five years, and the commercial use of drones may be widespread by 2017. Just this week, Norway announced that a drone collided with a “low-wing, two-seat monoplane” on Aug. 30. “The whole idea of these drones coming into conflict with other aircraft is something that I'm extremely concerned about,” Federal Aviation Administration Administrator Michael Huerta recently told NPR. But how concerned should you be during your next flight?
