A Delta Air Lines flight is reported to have been struck by a firework during landing at Chicago Midway International Airport on July 4. Multiple reports describe the incident as occurring while the aircraft is landing, though specific details about where on the aircraft the firework impact occurred were not consistent in the available information. The reports also describe the onboard situation at the time: 52 passengers and six crew members were on the flight when the firework struck. The sources indicate the event is under investigation and does not provide conclusive information on whether there were injuries or the extent of any aircraft damage. The reports focus on the timing of the incident during landing and the number of people aboard, while leaving unanswered questions about the cause of the firework being present near the airfield and what immediate operational steps were taken afterward. Authorities and the airline are expected to review the circumstances surrounding the incident as part of standard aviation safety and incident-response procedures.
