That's true - I guess if the length of the airship frame on the top is greater than the bottom (which from the photos it looks like) it will create lift no matter how blunt it is and how much drag it also produces.
- FabHK 4y agoFWIW, it is not necessary for a surface to be asymmetric (“longer” above than below) to create lift. This can be seen from the fact that (some) aircraft can be flown upside down.
