What is a UFO?

UFO - these are unidentified flying objects: no one knows exactly what they are. Many researchers (called "ufologists") have theories with which they try to explain what UFOs are, but since no one can study UFO in a scientific laboratory, all these ideas are nothing more than scientific assumptions. The following definition can be proposed UFO , which may be useful when considering this topic:

UFO - is a publicly reported observation of an object or source of light in the sky or on the ground whose appearance, trajectory, actions, movements, emitted light and colors have no logical or natural explanation and which cannot be explained not only by witnesses but also by scientific and technical experts who attempt to explain the observation after examining the evidence
(definition of the American UFO Association CUFOS).
