(Preble County, OH)--A pilot walked away from a small plane crash in Preble County Tuesday night.  At around 9 o’clock, a man knocked on the door of a home on Oxford-Gettysburg Road and said that he had just crashed his plane in a nearby farm field.  First responders found the plane on its top.  The pilot said that he was having engine problems and landed in the soft field.  "It was a bumpy landing.  I think he was trying to put it down where he could because of the engine problems.  Based on the plowed field, I think it just sucked those tires in and stopped him very quickly," said Preble County Sheriff Mike Simpson.  The pilot was taken to Reid Health with minor injuries.  The NTSB will be investigating.
