Two planes slid on runways at Chicago's O'Hare International Airport Tuesday, officials said.
A corporate jet, which had two passengers on board, exited the runway just after noon, according to the Chicago Fire Department.
Chicago Department of Aviation spokeswoman Karen Pride said the aircraft, operated by a company called Net Jets, was originally destined for Executive Airport in Wheeling.
No injuries were reported, but the incident is under investigation, Pride said.
An American Airlines plane with 65 passengers and five crew members on board was also heading out for departure when it slid on the taxiway and needed assistance straightening out, the airline said.
American Airlines Flight 1051, a McDonnell Douglas MD-83, requested to be towed to the terminal after sliding on Taxiway J, according to the Federal Aviation Administration and the airline. The plane is expected to take off later Tuesday after it has been de-iced.
The FAA is investigating both incidents.
More than 400 flights flying in and out of Chicago were canceled Tuesday ahead of snow forecast for several northern suburbs.
An icy mix of freezing rain, sleet and snow began to fall Monday night and continued into Tuesday morning before turning to all snow.
