Severe thunderstorms over Chicago on Sunday caused widespread disruptions to air travel, leading to dozens of flight diversions. One flight required three attempts to land amid the adverse weather conditions. In addition, two commercial flights departing from Boston's Logan International Airport were forced to return shortly after takeoff. The Federal Aviation Administration (FAA) has announced an investigation into the sudden return of an American Airlines flight to Boston. The storm also caused significant ground delays at Denver International Airport, impacting hundreds of flights, with Southwest Airlines service at Denver International Airport and St. Louis Lambert International Airport experiencing the most disruptions. The approaching storm featured a distinctive shelf cloud as it moved into the southwest side of Chicago, further complicating air traffic at Chicago’s Midway Airport.
