"Hollow tubes? Or is it better to do a half loop with lightening holes?" One of the others asked.
"Let's design both. It's easier to build the model and put it on the scale than to calculate the weight savings." Dominic suggested.
Gully laughed. "Trust the Dragonkin to have the practical answer. You would be a terrible researcher, but I like the way that you think."
"What should we start with? Just regular aluminum to see how extreme the construction methods need to be?" One of the older dwarves suggested.
"That's not bad. Go for aluminum, with thicker hull plating, and a double layered gas envelope. That's peak safety procedures, even if it will hurt our cargo capacity." Gully agreed.
