At 2100 central time, a Cessna 210M lost engine power and was damaged in the ensuing forced landing. The pilot reported minor injuries. The pilot had flown 1.1 hours from Minneapolis to Morris, Minn., earlier in the day and was returning to Minneapolis. The return leg had lasted about 2.5 hours because the pilot was shooting approaches at other airports on the way back. The pilot told investigators he had forgotten to switch fuel tanks and, when the engine power vanished, he was indecisive about picking a forced landing site.
