Best random find I encountered, was at a clearance sale at the student bookstore, at Whatsa Matta U, in the 70s.

iirc, what was driving the project was a missionary project to deliver Bibles in Africa. To perform the deliveries, the group developed a hybrid of a zeppelin and an airplane. I remembered the original, triple hull attempt, appearing on the cover of an early 60s issue of Mechanix Illustrated. In the early 70s, a guy in one of my drafting classes brought in a Christian magazine he had, with a two page article about their second attempt at a craft. So, when I saw the book in the clearance sale, I knew what it was about, and snapped it up.
