How did saucer got its name?

The term "saucer" in relation to flying saucers originated in 1947 when pilot Kenneth Arnold reported seeing nine unusual flying objects near Mount Rainier in Washington. He described their motion as resembling "saucer-like" movements, and the media picked up on this description, coining the phrase "flying saucer." The name stuck, and it became widely associated with UFOs in popular culture.
