A Cessna private plane with three people on board has gone missing after taking off from Fleming Field in South St. Paul on Sunday afternoon. According to a press release, the Washington County Sheriff’s Office and the Cottage Grove Police and Fire Departments began a search for the missing plane on Sunday evening. They were assisted with the search by the Stillwater Fire Department and the South Metro Fire Department. Based on information provided by officials at Fleming Field, search teams believe the plane is located in a water-filled quarry on Grey Cloud Island, south of Mooers Lake and north of the Mississippi River. Throughout the evening, deputies and officers searched the quarry with boats and lights but were unable to locate the plane. However, they did find plane debris leading them to believe they were searching in the correct area. Washington County Sheriff’s Office Dive Teams will be in the water attempting to locate the missing plane. The search operation conditions are difficult, as the quarry walls are sand-based and the quarry itself is up to 200 feet deep. The quarry, and property surrounding it, is owned by a private business. Investigators from the National Transportation Safety Board and Federal Aviation Administration will be leading the investigation once the plane is found.
