The mid-size corporate jet was on the second leg of a charter that began Monday, and anything wrong was reported before the crash. The plane left Dayton-Wright Brothers Airport and was approaching Akron Fulton International Airport. The Federal Aviation Administration, the National Transportation and Safety Board and State Highway Patrol are investigating what caused the crash. Some investigators will remain at the scene overnight, but much of the work will be done Wednesday morning. “It was a perfectly well-maintained aircraft with no squawks,” the owner and operator of the plane, Augusto Lewkowicz, told to the media.
