The UFO Structure

Whenever we describe an UFO, we always make or imagine a disc-shaped machine which flies in the sky. This shape might be for its smooth movement in air, in wormholes (if they use this technology) or in any other circumstances. The light that comes out from the bottom center of the UFO, it is shown to be abducting any object under by pulling it upwards. This means some gravitational force is being applied which is more powerful than that of our Earth. The machinery inside is not known but whenever UFO lands, its legs come out which rest at ground and hold the weight of the UFO. The most mysterious thing it takes with it is obviously aliens. The NASA's faster than light spacecraft when compared to UFO, which performs same work, is double the size of an UFO and more complex even. Although, Science has improved a lot as compared to Ancient times science has to improve more to match their technologies.
