National Transportation Safety Board investigators have released early findings in this month's fatal plane crash in Decatur County.

Listen:

The report indicated investigators did not find anything wrong with the plane or its engine, but found reports of foggy, misty weather the night of the crash.

Clouds were too low, so was visibility.

Pilot Don Horan's friend tried to land a different plane at the Greensburg Municipal Airport less than an hour before the Dec. 2nd crash, but missed the runway approach and decided to land in Columbus. But Horan stuck to his plan to land in Greensburg.

The plane hit the ground, killing Horan and his wife Barb. It also killed their friends Stephen and Denise Butz.

A final report is expected to have greater detail--including information stored on three data boxes found in the wreckage.
