Whirly Birds

I give this book a 7 . I really enjoy this book! It is nice to find out how helicopters are made and what they are used for. I am glad that people decide to come up with the idea to build helicopters because they have got alot of people out of bad situatations and saves their lives. People also use helicopters to get them back and forth work. Police use them for work .Some radio station use them for broadcast from the ski, and they also use them to film movies. BY ANDREW
