GLASGOW (AP) - Authorities on Friday were searching for a small plane that disappeared while on a flight from Mobridge, S.D., to Cut Bank.
Authorities believe four people, including the pilot, were aboard the single-engine Cessna 182. It last made radio contact at about 6:30 p.m., Thursday, when it was near Glasgow.
Officials reported snow and poor visibility at the time. Gary Mayer, regional operations officer for the Federal Aviation Administration, said the airplane is believed to have an emergency locator beacon that would most likely be activated in a crash. Authorities had not picked up any beacon, however, he said.
Officials did not immediately release the identities of those aboard the plane.
Debbie Alke with the state Department of Transportation's Aeronautics Division, said the agency, along with the Montana Highway Patrol and local search crews, were attempting to find the plane, concentrating on an area between Glasgow and Havre.
She said officials had hoped to launch an aerial search, but poor visibility was preventing that Friday morning.
"The weather is marginal right now," she said. "We do have aircraft ready to launch, readily to help in the search, but we're waiting for the weather to clear first."
She said authorities were seeking help from the public as well, hoping area residents may have heard or seen a plane late Thursday.
The plane is described as white with small tracings of blue. Alke said the plane's color could make the search harder, since the Glasgow area received several inches of fresh snow since Thursday morning.
