Nine people—including two children and the pilot—have been killed after a plane crashed in South Dakota, authorities tell CNN. Peter Knudson with the National Transportation Safety Board tells the AP that 12 people were aboard the Pilatus PC-12 when it crashed about 12:30pm Saturday, shortly after taking off from Chamberlain, about 140 miles west of Sioux Falls. The single-engine plane was bound for Idaho Falls, Idaho.
The Brule Buffalo County Emergency District says the crash was weather-related. Media reports say Chamberlain and central south-central South Dakota were under a winter storm warning at the time of the crash, and the National Weather Service notes that snow was falling at up to an inch an hour in South Dakota. Knudson says weather will be among several factors NTSB investigators will review. He says inclement weather is making travel to the site difficult. "The men and women of law enforcement, first responders and medical professionals should be commended in their heroic actions to rescue the victims in the extreme weather conditions," Brule County States Attorney Theresa Maule Rossow said.
