The book does not aim to be a technical primer or a flight by flight tale of test flying, though I have added one or two flight test records to give the reader a feel of how it was done and also some graphs of the measurements I helped to make before the first Vulcan was delivered to the Royal Air Force. The book is mainly for people not particularly associated with the Vulcan, though it is hoped that the aficionados will enjoy having their memories jogged. I have tried to explain some of the more complicated aeronautical expressions and included a Glossary to help readers who are not familiar with the jargon. I have done this because the Vulcan is a UK icon and I want as many people as possible to appreciate the work that went into developing the aircraft. It has captured the imagination of the whole country and represents what this country can achieve when it sets its mind to it.
