The countdown is on to the start of the Indy 500, which was delayed from its traditional date in May because of the coronavirus pandemic and will be run without fans for the first time in its 104 editions.New track owner Roger Penske, whose team has four cars in the field, and IndyCar executives have tried to create an entertaining prerace show for broadcaster NBC. But the build up to “The Greatest Spectacle in Racing” is still somewhat eerie without the 250,000-plus fans who typically show up inside the Brickyard.Driver introductions took place with the voice of the public address announcer echoing off the empty stands.

But there will be Jim Cornelison singing “Back Home Again in Indiana” and the Air Force’s famed Thunderbirds performing a flyover.___More AP auto racing: https://apnews.com/apf-AutoRacing and https://twitter.com/AP_Sports James Davison has brought out the first caution flag of the Indianapolis 500 when he made contact with the wall in the opening laps and his right front tire turned into a ball of fire.Davison was able to exit the car without any problem.
