We've borrowed several books on the Wright brothers from the library and this is the one my four year old son asks for over and over again. It contains many historical details, but the writing is simple enough for him to understand. The illustrations are a combination of historical photographs and some vaguely humorous cartoon style illustrations. A note to parents of younger children, many pages are half filled with text, but it's in a nice, easy to read larger font. Half a page is (very roughly) about 80 words. My son loves books in general and has the patience for a longer story, so he's happy to sit quietly, devouring every word. And I will confess that as a Mom, I am also partial to this version because pays tribute to the role that their Mom's handy/crafty nature (she often made furniture, toys, and clothes) had in their cultivating their inventiveness. If your child is plane obsessed like mine I think they'll enjoy this book.
