A plane crash killed five members of a group of skydivers Saturday in northwestern Montana. The Federal Aviation Administration in Seattle said the plane went down shortly after takeoff, then burned. The pilot of the Cessna 182 operated by Skydive Lost Prairie was carrying two skydiving instructors and two trainees to jumps, said Michael Morrill, a manager of the company. Morrill said the plane took off in clear weather. Names of those killed were not released immediately. All were from Montana, Morrill said.
