ET Transport is a term used to describe extraterrestrial transportation, which includes both saucers and UFOs. A SAUCER is a type of flying vehicle that is typically round or disc-shaped and is often associated with alien life forms. UFOs, or Unidentified Flying Objects, are objects seen in the sky that cannot be identified and are often thought to be of extraterrestrial origin. Both saucers and UFOs are commonly used as a form of ET transport.
