Pigott has authored various texts on the subject or gliding/soaring and I have found them all to be useful.
This particular one is throughly detailed and definative. Everything you could possibly wish to know about gliding is within and it makes a handy companion to Pigott's books aimed at the student pilot.
This book is simple to read and understand and the writing style is a pleasure to follow, which makes following it so much easier. It reads like a good novel and I found myself just wanting to read the next page for more and more information. The reader is left with a thorough understanding of how the gliders fly, the manoeuvres and good airmanship.
After gliding in the UK I now PPL it in the US. This book makes me want to be back at the Long Mynd!
