Montana Plane Crash Tribute

US officials have launched an inquiry into the cause of a plane crash in Montana that killed 14 people, including seven children.

The light aircraft nosedived into a cemetery near the town of Butte on Sunday. There were no survivors.

The pilot was flying from Oroville, California, when he diverted to Butte, officials said. He tried to land but crashed 500ft (150m) from the airport.

The children were probably going on a ski trip, officials said.

Karen Byrd of the Federal Aviation Administration (FAA) said seven adults and seven children had been killed.
