I read this while I was doing a gliding course at Sutton Bank Yorks, to cover the time when the weather was not so good for flying.
Richard is more well known for 'Jonathan Livingston Seagull', an oft used text to prove perspective on life. This text provides a view of his own flying experiences as documented in the late 1960's and early 1970's (about when I was born!).
It costs a bit more to fly now (aftrerall it was written 40 years ago), but the sentiment in the collection of essays is the same. Having flown too, the energy and feeling you get from the text does fit with the feelings from the cockpit and people you meet (often there are characters!).
In terms of style, it may at times be a little over the top (hence four out of five). However, each chapter is short and also delightfully illustrated with pencil drawings of many kinds of aircraft. Each drawing fitting well with each short chapter.
