Although Understanding Flight is a "textbook", it delivers the fundamental concepts behind why things fly. It is a non-fiction book that is great for readers with a love of learning how things work. First off, it uses simple diagrams and real life situations to convey the ideas of learning. This creates a more easy-to-read for the reader while still being able to be an informational book. Inside the book, you'll find the concepts involved in pressure differences, forces, laws, and situations in which looks are deceiving. All in all, the book is a great source of information for the mechanically-inclined and interested reader.
