There are new details surrounding a fatal plane crash near Sanborn, Iowa
According to the National Transportation Safety Board, weather conditions were not a factor which lead to the crash of the single engine plane back in late June.
Instead, two witnesses near the crash site saw the plane flying at low altitude, and heard the engine "coughing and sputtering."
The engine quit shortly there after, and quit once again after it got restarted.
The crash killed three Wisconsin men in June. It departed from Fort Atkinson, Wisconsin and was en route to South Dakota.
