About
Who flies rescue helicopters? What does the inside of a rescue helicopter look like? Learn all about these important machines in this book. The huge wheels, powerful engines, and loud noises of working machines seem to entrance children for hours. Now young students can pore over color photos as they learn about their favorite machines--inside and out. Each book builds vocabulary as it describes in simple language the basics of a machine: what it looks like, what it's used for, and how it works.
