In 1961, Betty and Barney Hill were driving through the White Mountains of New Hampshire when they experienced a terrifying, two-hour abduction by extraterrestrial beings. The couple's traumatic encounter, which they only recalled under hypnosis, left behind physical evidence on Betty's dress, including a mysterious pink powder and strange tears. This case, which has been the subject of intense scientific and public debate for decades, remains one of the most compelling and well-documented accounts of alien abduction in history.
