The craft's fuselage plunged into an Ohio River country farm at a speed of over 600 miles per hour and disintegrated. The Federal Bureau of Investigation sent agents to the scene to determine whether there was any violation of federal law. Such an investigation would include the possibility of sabotage. State Police Sgt. Joe O'Brien said that the plane was last heard from over Scotland, Indiana, about from the crash site. He said the pilot, Capt. Edgar LaParle, had reported rumble and the weather was very muggy and cloudy.
