An 84-year-old Huntsville man is among two people on board a plane that is believed to have crashed near Yellowstone National Park.
Park County sheriff's officials say the 1963 Mooney M20C was last seen Tuesday departing Yellowstone Regional Airport in Cody. On board were 84-year-old Robert L. Zimmerman of Huntsville, and 86-year-old Ward H. Zimmerman of Seattle WA.
The plane's route was from Cody WY to Twin Falls ID, and then on to Seattle. Radar last detected the plane about seven miles outside Yellowstone's east entrance.
Poor weather conditions have hampered efforts to perform an aerial search, but ground searches were in progress on Sunday.
On Monday, the search will be focused on Yellowstone National Park.
