Welcome to the Explorers Unlimited guide at TV Tome. Ruth Kotila, then of the Bedford (Ohio) City Schools, hosted these field trips. After a short in-studio tease, Kotila looked through "The World Beyond the Window," and the filmed field trip began. After the field trip, Kotila looked in a small box to find a clue about the field trip in the next program. [b]Explorers Unlimited[.b] yielded 33 field trips over two seasons. The first sixteen shows were filmed in 1971 and the final seventeen in 1974. There is no editor for this show. If you would like to be the editor look here for details.
