In front of 4 witnesses on Nov 5, 1975 Travis Walton was allegedly abducted by a UFO when an object he approached zapped him with a light and lifted him into the craft. Walton was missing for 5 days before returning with no initial memories to account for any of that time. Over time and in some cases under hypnosis, Travis has recalled some of his time aboard the craft. Everyone involved passed numerous subsequent lie detector tests.
