Whilst the matter contained in this book is intended as a popular exposition of the subject it includes information which may assist the reader with serious intention of making an attempt to produce a flying machine, or airship. A great deal of sound experimental work has been done by many investigators forming a basis upon which future plans can be calculated. An account of some of this work is given in these pages, and though necessarily incomplete will give an idea of what has been accomplished and that which may be possible. Further sources of information are indicated so that the reader may extend his search if he desires to do so. It has not been considered advisable to include mathematical formulae or to attempt calculations for designs as these are beyond the scope of the book. Flying machines of the past are taken to be the models and machines used by experimenters of intelligence and scientific ability.
