Tug flips over, pins 64-year-old man at O’Hare International Airport.

The driver of an aircraft tug was sent to the hospital in critical condition after an incident at O’Hare International Airport in Chicago on Saturday, according to the Chicago Police Department.

The wing of the aircraft struck the tug vehicle as the plane was taxiing to the gate, police said.

The passenger plane was operated by American Airlines under American Eagle Flight 6181, the airline confirmed to Fox News Digital in a statement.

“Nothing is more important than the safety of our customers and team members, and we are reviewing this incident,” American Airlines said.

The Federal Aviation Administration (FAA) also confirmed the tug was reportedly crossing the taxiway when it was hit by a Bombardier CRJ-200, which flew from Kalamazoo Battle Creek International Airport in Michigan.

Upon contact, the tug vehicle flipped over and pinned its 64-year-old male driver, whose name has not been released, according to the police. The driver was later taken to Lutheran General Hospital with head and lower body injuries but is now stable.

United Airlines also confirmed that the tug driver was one of its employees.

“We are ensuring he receives any necessary support and care,” United Airlines said in a statement.

No other customers or crew members were injured in the incident, police said.

The FAA also stated that the passengers were deplaned safely and bussed to the terminal.

The investigation is ongoing.
