Authorities say two people have died and a third was injured when a small plane crashed in Detroit while heading to the city's municipal airport. Detroit police Capt. Mark Thornton told reporters the single-engine plane en route to Coleman A. Young International Airport apparently struck a power line and tree Sunday night. He says it burned in a vacant lot. Thornton says "courageous citizens" rescued the survivor, AP reported. Thornton says a man and a woman died. The survivor is in critical condition. No one else was injured. Federal Aviation Administration spokesman Lynn Lunsford says preliminary information indicates the pilot reported a landing gear problem and low fuel shortly before the crash. The FAA and National Transportation Safety Board will investigate.
