For some reason in 1973, more Americans than usual imagined they were seeing UFOs. Maybe after trips to the moon, we thought we were due a visit of our own? Maybe the Vietnam-and-Watergate era was so surreal that everything felt alien anyway? Governor John Gilligan of Ohio, who thought he saw a saucer, is, of course, the father of Kathleen Sebilius, the current Secretary of Health and Human Services.
