A Delta Air Lines Airbus A319 (Flight DL1076) was struck by a firework mortar at approximately 200 feet while descending for landing at Chicago Midway International Airport on 4 July 2026. The crew reported a loud bang to air traffic control but continued the approach, landing safely without declaring an emergency. All 52 passengers and six crew members remained uninjured. Delta immediately withdrew the aircraft from service for inspection. Mechanics confirmed no structural damage, though Chicago Police noted minor paint abrasion. The Federal Aviation Administration is investigating the firework source amid Independence Day festivities. This rare incident underscores pyrotechnic safety risks near flight paths and prompts calls for stricter launch controls. Operators now face heightened scrutiny on approach zone security during peak holiday periods.
