An Alaska Air National Guard crew has swooped in by helicopter and rescued two people from a light plane down on Knik Glacier.

Federal Aviation Administration spokesman Ian Gregor says the two were uninjured. Gregor said he didn't know the circumstances that caused the Cessna 180 to land on the glacier. A passing aircraft spotted it Friday afternoon.

Staff Sgt. Karima Turner says an Air Guard Pave Hawk helicopter flew the plane's occupants to Providence Alaska Medical Center in Anchorage. They were not identified.

The glacier is about 50 miles north of Anchorage.
