Betty Hill of Portsmouth, who along with her late husband in 1961, had the first publicized and best-documented UFO experience in the White Mountains, died Sunday in her sleep after a battle with lung cancer. She was 85. On a return trip from Canada, the Hills said they were abducted for two hours by a UFO on Sept. 19, 1961. After going public with their story, the two gained worldwide notoriety. Their story became the subject of a book and later, a made-for-TV movie starring James Earl Jones and Estelle Parsons. They traveled across the country and made numerous television and radio appearances telling their story. When her husband, Barney, died in 1969, Ms. Hill continued the job alone. In 1995, she published, "A Common Sense Approach to UFOs," Ms. Hill’s life was not all about UFOs. She was a social worker for the state of New Hampshire where she trained foster parents and worked in the area of adoption. She was also an activist throughout her life where she was a member of the NAACP and a founding member of the Rockingham County Community Action. In addition to her husband, she was predeceased by her daughter, Rose Marie Stewart Norton of York, Maine. Ms. Hill is survived by her daughter, Constance Jean Stewart Zukowski of North Little Rock, Ark., a son, Kenneth James Stewart of San Jose, Calif., and a niece, Kathleen Florence Miller Maden of Stratham.
