A Look Back on Her Career

Spirit of Innovation was christened on June 21, 2006 in Akron, Ohio, where it was built. President of International Speedway Corporation Lesa France Kennedy and Lynn Keegan, wife of retired Goodyear CEO, performed the official christening duties. The blimp operated at the Goodyear Airship Base in Pompano Beach, Florida from 2006 to 2015 and completed its career in Carson, California from 2015 to 2017. It was the first Goodyear Blimp ever to be named by the public through a “Name the Blimp” contest.

During its 11 years of operation, Spirit of Innovation, covered 11 NASCAR and NCAA football seasons, Super Bowl XLIII and Super Bowl 50 Week activities and multiple Daytona 500’s and NBA Finals. The blimp flew over 5,800 flights and almost 34,000 flight hours.

Spirit of Innovation’s first telecast was over the Boston Red Sox at Cleveland Indians on ESPN on April 26, 2006. After more than a decade flying across the United States and Canada, Spirit of Innovation’s last telecast was over the 89th Academy Awards in Hollywood, California on February 26, 2017. The final flight was captained by Chief Pilot,Matthew St. John.

Wingfoot Two, the newest airship to join the Goodyear Blimp fleet will replace Spirit of Innovation in the Los Angeles market by the end of 2017 after the completion of the base renovations and facility upgrades.
