Wow, really useful! Personal Drones is no kindergarten picture book with scant info. This is actually an excellent resource for elementary and up! With plenty of photos, trivia, and mini-articles, as well as detailed specifics, I learned a lot of valuable information without having to slog through a boring tome. There were sections on the history of drones, current personal and commercial drones, military applications, and future uses that companies are looking into. I will definitely be adding this to my middle school library.
