The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot reported that as he entered the downwind leg of the traffic pattern for runway 18, at Kirksville, MO (irk) when he experienced "extreme vertical turbulence." The irk ASOS reported, at 1755 CDT, the wind from 320 degrees at 23 knots, gusting to 34 knots. The pilot reported great difficulty flying the aircraft on the downwind leg of his pattern. The pilot continued with the landing and upon touchdown, he was unable to stop the aircraft before the end of the runway. He reported, "I could see that I would be unable to stop by the time I reached the end of the runway. I allowed the aircraft to veer off to the west side of the runway because there were no obstructions there." The pilot reported that the airplane veered off the runway collapsing the nose gear and causing the left wing to strike terrain as it stopped. The propeller also struck the terrain while the engine was at idle. The right elevator and trim tab were damaged.
