The data of the first UFO sighting is not known. Some researchers say that UFO sightings date back to ancient times. There is no evidence for this speculation, so it is just a thought. Many researchers though mark the beginning of sightings in the United States in the later 1800s, they were called "The Mystery Airships". The next main fleet of sightings were during the Second World War, from pilots who say they saw metal like objects floating in the sky. These fighter pilots called them "foo fighters". And in 1947 in Europe, there were sightings of silent "ghost rockets". None of these speculations were ever fully explained.
