CHICAGO (WGN) The driver of a tug vehicle at Chicago O’Hare International Airport was injured Saturday evening after colliding with the wing of an airplane.

Chicago police said the incident happened just before 7 p.m.

Air Wisconsin Flight 6181, was approaching a gate at O’Hare, a statement from the FAA explains. It had departed from Kalamazoo/Battle Creek International Airport in Michigan.

The wing of an aircraft reportedly hit a tug as the vehicle tried to cross an active taxiway. The impact caused the tug to flip over, pinning the driver underneath it, according to investigators.

The driver of the tug, identified as a 64-year-old man, was taken to Lutheran General Hospital in critical condition with injuries to his lower body and head, but police said he has since been stabilized.

Passengers aboard the flight were deplaned and bused to the terminal, according to the FAA.

No other injuries were reported and Area Five Detectives and the FAA are investigating. In a statement, American Airlines, which currently has a partnership with Air Wisconsin Airlines, said it was “reviewing the incident.”

Air Wisconsin Airlines, an Appleton, Wisconsin-based regional airline, is a contracted carrier for American Eagle, a subsidiary of American Airlines.

The airline recently announced it is ending its partnership with American Airlines in April 2025. On Friday, the Milwaukee Journal Sentinel reported more than 500 employees of Air Wisconsin will be permanently or temporarily laid off due to “shifting operations” and the end of the American Airlines partnership.
