Holter, 5 times bigger and heavier and 5 times the lifting capacity. Also, IMO, with this type of construction technique the design of the airship shapes is unlimited. Change the nose cone plate from a round shape to an ellipical shape and you could see the shape of the Sans1 design, ie shark nose in appearance, but much lighter, easier to assemble and accessible for entry to the inside for installation of any and all necessary equipment. Seems to me that this new structural concept is a leap forward in design/assembly technology from other airships to date, but all just my opinions. ken w
