This book has many interesting features, from radio sets connected by string, to "radar blips" on a screen in a cockpit, little planes "flying" through the sky, to a steering wheel that changes the view out windscreen as you "come in for a landing--and that isn't even half of the activities in the book.

The problem is that it requires a high degree of fine motor skill to operate many of the activities. The "radar blips" were difficult for me to spin, for example, and the steering wheel kept getting stuck until mommy tore it in one of her many attempts to "Fix it!" under pressure. My son also removed all of the little "flying airplanes" in less than a week of play.

Don't get me wrong--my son still LOVES this book, despite the fact that it is now falling apart! He has a blast using the things that still work, and explaining to me how the things that are broken used to work.

I would recommend waiting until a child is at least four before buying this book for them unless they are very careful players or there will be parental help all the time it is in use.

And, I would like to add that the girls in my son's playgroup loved this book as well--it is DEFINITELY not just for boys!
