Feb. 2 (UPI) -- An aircraft tug collided with a plane that had just landed at O'Hare International and overturned, critically injuring the driver.
The Federal Aviation Administration said the collision occurred at around 7:35 p.m. CST Saturday, WBBM-TV reported.
Air Wisconsin Flight 6181 was hit by the tug while approaching a gate at O'Hare.
The impact caused the tug to flip over, pinning the driver underneath it, according to investigators, WGN-TV reported.
The 64-year-old man was taken to a hospital with injuries to his lower body and head, but police said he has been stabilized.
Air Wisconsin is a regional airline operating under American Eagle, which is a subsidiary of American Airlines. Three days earlier another American Eagle plane collided in midair with a Black Hawk helicopter and crashed into the Potomac River, killing all 67 aboard both aircraft.
Both incidents involved the Bombardier CRJ-200.
The Air Wisconsin jet had just arrived from Kalamazoo, Mich. No passengers were injured, the Chicago Department of Aviation said, and "there was no significant impact on airport operations."
The tug was operated by a United Airlines worker.
