What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Casper tower observed an aircraft on a 1200 transponder code in IFR weather southeast of Casper, Wyoming, and made contact with the pilot. He accepted vectors to the airport, but because of a rough running engine, he could not maintain altitude and landed in a field 2 miles north of the airport. No damage was incurred. A ground crew assisted him prior to departure from the emergency landing field. The pilot received clearance from the tower and landed at Casper airport.
