CHEYENNE, Wyo. (AP) — The search for a small plane missing in western Wyoming is now in its fourth day.

The Sublette County Sheriff's Office says 63-year-old pilot Myles McGinnis of LaBarge, Wyo., was the only occupant of the Cessna 182 that left Stevensville, Mont., on Saturday. The plane was bound for Pinedale but disappeared from radar between Jackson and Bondurant.

So far, crews searching the rugged terrain from the air and on the ground have yet to locate the plane.
