UFO is short for Unidentified Flying Object. It’s also called Flying Saucer. It is one of the most popular topics in the 20th century. With films like Close Encounters of the Third Kind and ET in the 1970s came a rapid increase in reports of flying saucers and men from Mars. More than 20 countries said their people once saw the UFO and there were over 1,200 reports about the UFO. Some even said they saw aliens.
In July, 1916, Gaynor was a nine-year-old girl and lived in North Wales. One day, on her way home from school, she saw a silver object in a field not far from her home. The object looked like a saucer. Gaynor was very scared. She stayed in the tall grass and watched the door of the strange object open. She saw two aliens wearing silver suits get ou. Then they use something to examine the ground. They were short and had pink eyes. After about half an hour, the two aliens went back into the object. Then it took off. When Gaynor got home, she told her mother about her unusual experience, but her family decided to keep quiet about it. They didn’t want others to laugh at their daughter. However, 18 months later, Gaynor told her story to UFO scientists. They found out that Gaynor told the truth.
