Northwest flight hits turbulence
The second line of storms that passed through here this afternoon also caused problems thousands of feet up.
At least two people were injured after turbulence forced a plane to make an emergency landing in Louisville.
It happened at the Louisville International Airport just after 6 p.m., when ambulances took a flight attendant from the Northwest flight to a local hospital.
The flight left Knoxville around 4:30 p.m. headed to Detroit. About 35 miles outside of Louisville the plane experienced "heavy turbulence" caused by storms in the area.
A flight attendant and a passenger were injured, but their injuries do not appear to be serious. The remaining passengers were placed on other flights.
