Drones have been buzzing in the news lately. Everyone has heard about Amazon’s plans for a drone delivery program, but the American public still has some reservations about the technology. When most people think of drones, they think of the U.S. military, which boasts an arsenal of 8,000 unmanned aerial vehicles. The armed forces’ largest drones, Predators and Reapers, are the size of Cessnas and F-16s, respectively, and look a little like something out of Blade Runner.
