Search crews Wednesday morning located a crashed plane on Lowe Peak in the Oquirrh Mountains that had been missing since radio contact was lost at 1:10 a.m.

Emergency rescue helicopters responded immediately to the scene.Two men flying a twin-engine plane from St. George to Salt Lake had contacted Salt Lake International Airport for landing directions, but radio and radar contact were lost. Soon afterward, transmissions were picked up from an emergency locator beacon, which is activated automatically on crash impact, in the Oquirrh Mountains, said Lt. Col. Jerry Wellman with the Civil Air Patrol.

The Salt Lake, Utah and Tooele county sheriff's offices, search and rescue ground crews, two Utah Civil Air Patrol airplanes and three helicopters began to search Butterfield Canyon, south of Kennecott Copper pit and west of Camp Williams, for the missing plane.

Identities of the passengers are being withheld.
