This book was a good introduction to paragliding for me, before embarking on a beginner's course. The front half teaches all the theory of taking off, landing and basic manoeuvring of the glider. Latter sections are more standalone and of interest to more advanced pilots thinking about using wave, becoming instructors or tandem pilots, acro etc. There is a very useful section about buying one's own wing.
As well as being a little out-dated, especially regarding navigation aids, radios and phones etc, the book is slightly marred by at times poor layout, strange spelling mistakes or word misuse and interesting diagrams with either flaws or just not labelled. Certainly there are some areas where additional diagrams might be useful and I think a lot more information is required about thermal formation, how and where to find them and how to centre etc.
I hope that these minor errors in what is otherwise a very good book are corrected in the later edition.
