Officials say a FedEx cargo plane landing at a Lubbock, Texas, airport veered off the runway, crashed and caught fire, but that both crew members walked away from the plane.

Lubbock Preston Smith International Airport director James Loomis says the ATR-42 twin-turboprop aircraft landed just after 4:30 a.m. Tuesday. He says crews extinguished the fire quickly.

The plane landed in a freezing mist, but Loomis says weather was not a factor in the incident.

The crew members were being evaluated at University Medical Center in Lubbock.
