We called them radio-controlled airplanes and if you have a son or daughter with a flair for building things and an interest in flight, I cannot recommend this hobby enough. RC aircraft aren't just a blast to build and fly, they're a superb, safe way for anyone of any age to soak up the engineering principles behind the art of flight without the significant expense of owning a real aircraft. Thanks to advances in electronics and engines, RC modeling has never been cheaper or more diverse. Today, hobbyists can choose between sleek, scale model SR-71 reconnaissance jets with ducted fan engines or RC gliders that can ride thermals for hours just like the real thing. With a little research you can find them ready to fly, right out of the box, for less than a hundred bucks. Unmanned aircraft have become ubiquitous; they now hover with cameras over sporting events, collect data for businesses, and even guard people and property. It seems like everyone, from Google to Amazon, is exploring further commercial applications. Needless to say there are more sinister uses ... Jump below the fold for a review of those lethal versions and look at a few of the disturbing questions they raise.
