Donald Albert Hall was one of the 20th century’s greatest aeronautical engineers and yet, most likely you’ve never heard of him. But I guarantee you’ve heard of the plane he designed, “The Spirit of St. Louis.” Within the cracked and weathered exterior of an old steamer trunk, a family secret was waiting to be discovered. In 1999, grandson Nova Hall discovered a locked World War 1 era chest in the families’ garage. This lost and forgotten collection of photographs, negatives, documents, design instruments, working models, film footage, and personal correspondence with Charles A. Lindbergh had amazingly survived years of neglect in no less than perfect condition. This book portrays the mysterious man behind the Spirit of St. Louis and his inspiring story of teamwork and dedication in the constructing of the most famous airplane in history.
