Accumulated ten hours of instruction in a sailplane twenty-five years ago, and haven't sat in the cockpit since. Needless to say, I have forgotten just about everything I learned. I think this is a great book because it is concise, easy to understand, and the illustrations are done well. Now, I just have to sell my house so that I can move close to an area with great soaring conditions, with a glider port fairly close by. :)
