Crews using a Navy robotic device continued searching Lake Powell on Thursday for a single-engine Cessna missing since April 24.
Searchers worked for a few hours Wednesday and all day Thursday, looking for the small plane with four people aboard that had left Page for Addison, Texas.The pilot and three executives from an Addison company were en route home.
The 3-foot-by-4-foot robotic device is "flown" by remote on the lake surface, tethered by a 600-foot cable, said Capt. Steve Lay, a spokesman for the Navy, which supplied the equipment.
The sonar and camera have seen little in Lake Powell so far, he said.
"A lot of rock," Lay said when asked what searchers have seen. "It is kind of early to see much. It's a tedious process."
Lay said the searchers are methodically searching two areas authorities believe the plane may be.
The water is at different depths, making the search that much harder, he said. He added that the team would remain on the lake through next week.
Those aboard the plane included pilot Mark Ballew and three executives of Univesco Inc., a real estate management company, David Warren, David Kalnes, and Theresa Gray. The president of the firm owns the plane.
An initial search for the plane was called off until family members called Sen. Kay Bailey Hutchison, R-Texas, asking that authorities resume searching.
Use of the equipment will cost between $20,000 and $25,000, Navy officials said.
