The NTSB is using drones in the Atlas Air flight 3591 crash. It may seem odd, but my favorite show on TV is Air Disasters. I chalk that up to being a former Aviation Safety Officer in my squadron. To be the ASO you actually have to go to a four week course, taught by Naval Postgraduate School and learn the intricacies/nuances of mishap investigation (from human factors to engineering investigations). I've been involved in one or two mishap investigations (not fatal, and relatively minor in the grand scheme of things) one of which resulted in identifying a software glitch in a 50 year old aircraft, which had previously never been identified. Anyway, I figured you guys might be interested in this article.
Drone technology, often thought to be at odds with aviation safety, has become a valuable tool for the National Transportation Safety Board.
