My own judgment of how the world is gonna end is that there will be a country led by a madman that will build a nuclear bomb with so much force, so much power, that it will be dropped somewhere on the face of this earth and that the earth will lose its place.

The Kings Island event scored the highest viewer ratings in the history of ABC's Wide World of Sports and would serve as Knievel's longest successful jump at 133 feet (although the Caesars Palace jump was longer it ended in a crash). The following day Evel appeared on stage with Robbie at Evel Knievel Days in Butte marking the last performance the two would appear together. Knievel was clearly in severely declining health but he still displayed the same spirit and showmanship that had driven his career.

His longest completed career jump came at Kings Island theme park in Ohio on October 25 1975 jumping 14 buses marking his peak television audience. After his recovery he continued to make high profile and lucrative jumps and began lobbying the government for permission to jump the Grand Canyon. After a failed landing which was caught on film Knievel spent 29 days in a coma.
