INDIANAPOLIS (AP): Andrew Luck is giving two Indiana children a memorable experience at Sunday's Indianapolis 500. The Colts quarterback will be joined by 11-year-old MaKenzi Rooksberry of Jasonville and 14-year-old Johliel Austin of Indianapolis on the IU Health Lifeline helicopter. They will land in the first turn of the racetrack, then hop into the official pace car and take a lap around the 2.5-mile oval before delivering the green flag that signals the start of the race.
