Was recently lent this book by a friend and found it a very interesting read. Its the story of Charles Redrup, a pioneer of rotary, radial, and axial engines for planes, buses, motorbikes etc. Plus a lot more! I know there's a lot of very clever and experienced engineers on the forum, and this would definitely be of interest. ISBN 978-0-9554455-2-1.
Another great read is The Lives of Ken Wallis ISBN 978-0-9541239-6-3
Happy reading
