The plane, a Cessna 185, lost altitude during takeoff from a checkpoint on the race trail Wednesday after dropping off supplies. Pilot Diana Moroney, 57, and a passenger were not injured, although the plane crashed onto the frozen Iditarod River and was "severely damaged," a statement from the Alaska State Troopers said.
It was the second plane crash involving the race this year. Monday, three people died when a Cessna 182 crashed near Rainy Pass, Alaska, the Anchorage (Alaska) Daily News reported Thursday.
In the race, four-time winner Lance Mackey, 42, led at the halfway point as the competitors arrived at the ghost town of Iditarod, the newspaper said.
