Portage County Police Close Encounter and Pursuit (1966)

1966; the exact calendar date is not stated in the extracted Chapter 8 passagePortage County to Conway pursuit corridor, Ohio / Pennsylvania, United States

Multiple police officers sequentially reported a brilliant low-altitude object during a pursuit from Ohio into Pennsylvania. Hynek uses the case as a representative Close Encounter of the First Kind and sharply criticizes Project Blue Book's Venus/satellite explanation and limited initial interviewing.
