About This Book

The book surveys the development of human flight from early passive balloons through powered dirigibles to heavier-than-air craft, emphasizing substantive advances rather than anecdotal or unproductive experiments. It follows technical evolution—balloon types, non-rigid and rigid airships, model and manned gliders, and the rise of stable, powered aeroplanes—supplemented by plates and historical sketches. A substantial section explains atmospheric science relevant to navigation, examining air density, dynamic lift and resistance, prevailing currents, storms, and local gusts that affect performance and safety. Appendices gather quantitative data, mathematical notes, and experimental records for specialist readers while the main text addresses an informed popular audience.
