I’m assuming this is the father of William?

Correct! Current editions include a foreword written by William.

Wolfgang is much better known for Stick And Rudder, which is about technical aspects of aviation.

If you want romance of flying, and depending on your style of "romance", you might try _Glacier Pilot_ a biography of Bob Reeve who came back from flying in South America as a bush pilot with undiagnosed polio, made it to Alaska, and perfected the art of crash landing on glaciers as a perfectly normal way of doing business. The book was written by Beth Day (Romulo?) who I believe was his granddaughter.
