On October 25, 1975, Knievel successfully jumped 14 Greyhound buses at Kings Island. Although Knievel landed on the safety deck above the 14th bus, his landing was successful and he held the record for jumping the most buses on a Harley-Davidson for 24 years. The record was later broken by Bubba Blackwell in 1999. The Kings Island event scored the highest viewer ratings in the history of ABC's Wide World of Sports and would be Knievel's longest successful jump at 133 feet (although the Caesars Palace jump was longer, it ended in a crash). After the Kings Island jump, Knievel again announced his retirement.
