SIOUX FALLS, S.D. (AP) — A small airplane heading back to South Dakota after a Texas cattle sale crashed into a wind farm in foggy weather, killing the pilot and three passengers. Steve Stengel, a spokesman for Florida-based NextEra Energy Resources says the wreckage was found at the 27-turbine South Dakota Wind Energy Center. The FAA says the single-engine Piper found Monday was registered to Donald J. “D.J.” Fischer of Gettysburg, South Dakota. Funeral homes confirmed the deaths of Fischer and cattlemen Brent Beitelspacher, of Bowdle, and Logan Rau, of Java. The fourth passenger was not named. The National Weather Service in Aberdeen says fog and low clouds combined for reduced visibility in the area Sunday night. Winds were out of the east at about 15 to 25 mph and there were scattered showers.
