Sectioned view of a "space discus". The discus form of the mother ship, which is approximately 250 m in diameter, is a compromise between a maximum surface area for cooling and a minimum frontal area with a maximum capacity. This is the universal solution for space travel at cosmic velocities. The power source, a "sun-wheel" (two opposed cyclotrons with an outer ring for the control of weightless energy) is unknown to US and demands the circular planform. The danger of collision with cosmic dust at relative speeds necessitates the smallest possible frontal area. The two smaller modular discs are in fact landing units, the mother-ship always remains in space. Electro-magnetic fields, high temperatures, and the ionization of the surrounding air, make it impossible for Us to see these craft in clear detail. A race that can finance such machines is by axiom peaceful, they need global Cooperation before it is possible.
