The third installment of NASCAR’s street race in Chicago is back this weekend as the sport takes over Grant Park for another year. And while there is now future commitment to the race coming back, fans will hopefully be treated to a spectacle in the Windy City.

A Chicago-bound flight was forced to make an emergency landing early Tuesday morning after the crew reported “possible smoke in the aircraft,” the Federal Aviation Administration said. The incident happened around 6:40 a.

Beyond tens of thousands of expected attendees, Chicago’s telegenic lakefront and skyline will once again serve as a live backdrop to race cars careening around an urban circuit.
