In 1966, Ohio cops chased a UFO into Pennsylvania. Then the government got involved, and things got really weird.

Cleveland Scene: The Ravenna case attracted the attention of Dr. James E. McDonald, the physicist, meteorologist, and former Naval intelligence officer who spent most of his career in the 1950s and '60s arguing for real scientific inquiry into the UFO phenomenon.

The incident "calls for reevaluation not only on the scientific grounds involved, but also to avoid unfairly subjecting to local public ridicule the several officers who have testified," he wrote. "The available evidence (especially Wm. Weitzel's extensive report for NICAP) seems to me to make the astronomical explanation, that now stands as the official Air Force evaluation, quite unreasonable."
