Southwest Airlines flight 1243, traveling from Fort Myers, Florida to Chicago, experienced a loss of air pressure in both nose‑gear tires as it touched down at Midway Airport on August 3, 2026. The depressurization produced visible smoke, prompting airport personnel to halt operations and have the aircraft towed away from the runway. No injuries were reported among passengers or crew.
Chicago Fire Department units arrived promptly after the smoke was observed. Firefighters secured the immediate area, confirmed that the situation was limited to the tire issue, and coordinated the safe removal of the plane. The aircraft was then towed to a designated holding spot for further inspection, while passengers were escorted off the jet without incident.
The flight had originated in Fort Myers and was on schedule for its Chicago destination when the tire problem emerged during the landing roll. The loss of pressure in the two nose‑gear tires is a mechanical fault that can generate smoke as the brakes and gear components heat up. Airport officials conducted a quick visual assessment, and the decision to tow the plane was made to prevent any potential damage to the runway surface.
While the incident required the temporary closure of the affected runway and the diversion of other traffic, the prompt response by airline staff and the Chicago Fire Department ensured that the situation was contained without harm. The aircraft will undergo a thorough maintenance review before returning to service, and passengers continued on alternate arrangements to reach their final destinations.
