I ONLY READ ABOUT 200 PAGES and mostly looked at the cool pictures on the other pages. I learned a lot about airplanes in this book and for a month I remembered different engines and the range of the planes but it was too much information. There were a lot of planes that I remember from 3rd grade because I was into WW2 and knew everything about it. There is a lot of cool short stories that tell about different parts of the world and how peoples lives changed during this time. There is also many subsections that make you think your reading a different book.
