Hermann OberthIt is my conclusion that UFOs do exist, are very real, and are spaceships from another or more than one solar system. They are possibly manned by intelligent observers who are members of a race carrying out long-range scientific investigations of our earth for centuries.
Hermann OberthToday, we cannot produce machines that fly the same as UFOs do. They are flying by means of artificial fields of Gravity. This would explain the sudden changes of directions. This hypothesis would also explain the piling-up of these discs into a cylindrical or cigar-shaped mothership upon leaving the Earth.
Hermann OberthIt is my thesis that flying saucers are real and that they are space ships from another solar system.There is no doubt in my mind that these objects are interplanetary craft of some sort. I and my colleagues are confident that they do not originate in our solar system.
