4/5 Weakness? Burgess underestimated longitudinal bending from gusts – something the USS Shenandoah paid for. But his failure analysis was honest. 2/5 Key insight: Don’t just strengthen the keel

In the mid-1920s, as rigid airships captured the world’s imagination, Charles P. Burgess—a key figure at the U.S. Navy’s Bureau of Aeronautics and later NACA—published a seminal work simply titled Airship Design . If you’ve come across a PDF bearing his name, you’ve found a masterclass in pre-Zeppelin structural logic. 4/5 Weakness
