It's a bird! It's a plane! No, it's a plane's tire – falling from the sky. Residents of a Chicago residential neighbourhood were shaken up recently after learning that a tire belonging to a small plane fell from the sky. The single-engine Pilatus PC-12 had departed from Ironwood, Michigan, and was flying over a neighbourhood in Chicago when the tire fell off shortly before landing. Following the incident, the Boutique Airlines aircraft managed to land safely at O'Hare International Airport around 6:40 p.m. Rose Bock – a resident of Jefferson Park, which is a neighbourhood located about seven miles from the airport – told the AP that she heard a big boom when the tire fell. Later, she said, the wheel was found in a neighbour's yard. According to the FAA spokesperson, seven people were aboard the plane during the scary incident. The AP reported that the group was made up of two crew members and five passengers. As the plane landed, the Chicago Department of Aviation told the AP that the aircraft was missing its left side landing gear and that sparks were flying on the runway. Thankfully, no injuries were reported from those on the plane or on the ground.
