U.S. investigators planned Friday to search the wreckage of a small plane for clues to why it crashed near a regional airport, killing all eight people on board, AP reported. The victims included two pilots and six passengers, all casino and construction executives who were heading to Owatonna, Minnesota, for a business meeting. The Raytheon Hawker 800 went down Thursday morning, shortly after severe weather had moved through southern Minnesota. The weather conditions, as well as the plane's structure, its systems and other factors, are being examined by the National Transportation and Safety Board, said John Lovell, the investigator in charge.
