The ships are constructed basically in space, they have no landing gears for contact with planets, nor do they have any junction for physical contact between them. (It is not necessary – editor’s comment.) Their structure has no weld joints, screw-bolts or any other joining elements; the shell and the framework are made of one original material (not by founding – alloys), and this is done by means of materialization of the thought directly in the space. Every such ship is unique and is built for an unlimited period of service (life-cycle). Older ships are not scrapped, but they are normally used and older parts (aggregates, devices, instruments, etc.) are gradually replaced by more modern ones. In principle, the ships have several types of propulsion for both securing the reliability as well as various modes of flight. The fault rate of the ship as a whole is zero. Mother ships are specific in that they are actually cities and they have a number of unsubstitutable functions. Every ship has its spiritual – informational field which depends on thoughts of the crew members. The crew has always a comfortable and spacious equipment; the size of the ship determines the maximum duration of stay on the ship. For example, for our ships of 1.5 – 2 km length, it makes about half-year of stay counted in your time. Ships of such dimensions fly in formations, e.g., five ships; they cooperate on tasks and in the event of theoretical failure, four other ships can tow the malfunctioned ship in their energetic veiling (hanger). But this doesn’t happen, it is absolutely exceptional, rather theoretical case.
Physical contact with planets is not neccessary because the larger ships are fully independent. Landing is done with smaller crafts. After Quarantine Earth is broken, if the population agrees (free will is always respected in the positive galactic society), this may occur.
In the Universe there exist both physical and spiritual beings, and also those in between.
