It wasn't the Fireball, Dave. The one you're referring to operated at Riverview Park in good old Chicago,IL. Unfortunately, Riverview and the Fireball closed forever in 1968. I have a book with the ad for it claiming to go 100 MPH, when it had only about a 70 foot drop (although it was very steep and went under the staion :))
