What is it about the rigid composite airship idea of such applied
technology that's over your DARPA head?


I'd like you to explain how you make a rigid shell light enought.
Remember increased atmosphere density also implies increased pressure.

Whilst hating to appear to support anything the Guthbot posts
I feel it necessary to point out that this is a red herring. As
long as you equalise pressures inside and outside the envelope
there is no reason for the shell to be any heavier than for a
terrestial airship.

The boiling sulphuric acid rain storms are another matter however.
