McManners could have titled his important new book 'Fly and Be Sustainable', with its bold and provocative vision for transforming the aviation industry from a laggard of the fossil fuel age to a linchpin industry of the future. Building on the industry's rich entrepreneurial tradition, his proposals could very well usher in a third golden age for the industry and provide a crucial step for a sustainable future. Whether this book disturbs, enlightens, angers or provokes into action, it provides a much-needed jumpstart to the debate on sustainability and deserves a wide audience.
