A sighting Thursday from the air of a light plane in the mountains in Kane County turned out to be a false alarm, a Kane County sheriff's dispatcher said Saturday.

The dispatcher said an Ogden area pilot and his observer, from Sunset, Davis County, saw what they thought might be the wreckage of a light plane, missing since mid-July. The craft had been en route from Burley, Idaho, to Chandler, Ariz.Sherman K. Flake, 53, and his son, Scott, 18, Mesa., Ariz., were last seen July 13 when they landed on a road near Fillmore, taxied up to convenience store and refueled their aircraft.

The sheriff's dispatcher said a search for the Flakes was called off several weeks ago. Lt. Col. Jerry Wellman of the Utah Civil Air Patrol confirmed that information. Wellman said the search Thursday was not initiated by the Civil Air Patrol.

The woman dispatcher said the two Utahns apparently saw wreckage from the air of a plane that crashed several years ago in the Glendale area of Kane County.

The dispatcher said the sighting Thursday occurred from a private plane, hired by the Flake family to look for the missing aircraft. She said a Kane County deputy sheriff accompanied the pilot and the observer.

Flake's wife, Karen, said Saturday her husband was flying a single engine, four seater metal-covered Piper Tri-pacer.

She said she and her family have been in a constant state of turmoil since the disappearance of their family members.

"Nothing can be settled" until they are found, Mrs. Flake said.
