The plane disappeared from radar on Sunday shortly after making a refueling stop in Fillmore, Utah. It was heading from Bakersfield, California, back to Gillette.
Four planes helped search for the missing plane around Fillmore yesterday.
The wing chaplain of the Civil Air Patrol in Utah, Stu Boyd, says no transmitter signals from the plane have been detected.
The plane was carrying pilot Matthew Ahrens, passenger Trista Meyer and her 9-year-old daughter, Shyann Lenz. Meyer’s mother, Myra Fees says Ahrens is an experienced pilot, and Meyer has been working toward her pilot’s license.
