Today, 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.
Hermann OberthThe rockets... can be built so powerfully that they could be capable of carrying a man aloft.
Hermann OberthWe cannot take credit for our record avancement in certain scientific fields alone. We have been helped, and we have been helped by the people of other worlds.
