THE PENINSULA
SHELL KNOB, MO
The Peninsula (21MU) in Shell Knob, Missouri, is a privately owned, non-towered airfield. A lone turf runway, 18/36, serves the field, measuring 2,800 by 40 feet.
No instrument approach procedures are published, so the field is used under visual flight rules. The non-towered field operates under see-and-avoid procedures, with pilots coordinating their own arrivals and departures. The field has no fuel sales on record. Its private-use designation means pilots need the owner's permission before landing.
The airport sits at 1,015 feet above mean sea level.
