A flying saucer pilot is a person who operates a spacecraft, usually of extraterrestrial origin. The term 'flying saucer pilot' is often used to refer to a SPACEMAN, or an 8-letter word for someone who travels in space, and an ALIEN, or a 5-letter word for a creature from another world. This job requires a great deal of skill and knowledge, as the pilot must be able to navigate the craft and understand its technology.
