Helicopters

By Ole Steen Hansen

Book Overview

Aircraft flying with rotors were imagined as early as the 19th century. It took many years and many failed attempts to find the successful design that we now recognize as a helicopter. Read all about the modern helicopters that fight forest fires, rescue people in trouble at sea, and take supplies to and fight at the front line during times of war. Book jacket.
