Two southeastern Indiana couples were killed when their plane crashed while approaching their small hometown airport in foggy, misty conditions, authorities said Monday. The crash Sunday night near Greensburg Municipal Airport killed pilot Don Horan, 46; his wife, Barbara, 44; Stephen Butz, 45; and his wife, Denise, 42, Greensburg Police Capt. Bill Meyerrose said. All four were from Greensburg and were heading back after a weekend outing in Florida with six others. They had taken off from Destin, Fla., and crashed just a mile from the Greensburg Airport. The six others who were part of the excursion flew in another plane that landed safely at a larger airport in nearby Columbus instead, Meyerrose said. The Horans have four daughters, and the Butzes have two sons. Victims IDed from small  plane crash  in SE Indiana Seattle Post Intelligencer GREENSBURG, Ind.
