MILWAUKEE (AP) — A military airplane has made a safe emergency landing in Milwaukee.

A spokesman for the Wisconsin Air National Guard’s 128th Air Refueling Wing says the crew landed safely and exited at Mitchell International Airport on Wednesday afternoon.

The KC-135 aircraft blew out two of its tires as it landed. The Milwaukee Journal Sentinel reports emergency vehicles surrounded the plane after it came to a stop.

The runway was temporarily closed. The plane was towed off the runway at 4 p.m., and the runway reopened and the airport resumed normal operations.

The Air Guard spokesman says the cause of the emergency will be investigated.
