Montanar...Another thing to consider. There were TWO military prototypes. I am assuming that there was the Skydragon and a Rigid type. The Skydragon can be launched, because of it's design, in wind conditions that the rigid ship cannot. I believe, from the pictures, it is also smaller. If so, the Skydragon would offer more versitility for battle field applications, while the rigid ship would be used in areas where wind and weather conditions would better allow its launch. In short, imo, they are two separate applications and designs.
