"Excellent structure"? I doubt it. If nasa did it, it's wrong. That is a good
starting point for CATS rocket analysis. Don't copy nasa. Do the opposite.
When you attach a piece of rocket structure to a stressed metal balloon
fuselage, you create stress failure points. The lightest-weight design isn't
the safest and easiest design for our alternate access to space.
Simply put, a tank needs internal reinforcement to be a strong fuselage.
You don't want the ship breaking apart when strong aero dynamic turning
moments are applied. Balloon tanks? C'mon. Highly inappropriate. success wishes
