CNN: The Brazilian air force said that debris picked up Thursday near where officials believe Air France Flight 447 crashed Monday into the Atlantic Ocean was not from the plane.

"It has been verified that the material did not belong to the plane," Brigadier Ramon Borges Cardoso told reporters in Recife about the material recovered Thursday. "It is a pallet of wood that is utilized for transport. It is used in planes, but on this flight to Paris, there was no wooden pallet."

He added that oil slicks seen on the ocean were not from the plane, either, and that the quantity of oil exceeded the amount the plane would have carried.

"No material from the airplane was picked up," he said.

The announcement left open the question of whether other debris that had not yet been plucked from the ocean might be from the plane.

On Wednesday, searchers recovered two debris fields and had identified the wreckage, including an airplane seat and an orange float as coming from Flight 447. Officials now say that none of the debris recovered is from the missing plane.

Helicopters had been lifting pieces from the water and dropping them on three naval vessels.

Brazilian Air Force planes spotted an oil slick and four debris fields Wednesday but rain and rough seas had kept searchers from plucking any of the debris from the water.

Officials said searchers had found objects in a circular 5-kilometer (3-mile) area, including one object with a diameter of 7 meters (23 feet) and 10 other objects, some of which were metallic, Brazilian Air Force spokesman Jorge Amaral said.

The debris was found about 650 kilometers (400 miles) northeast of the Fernando de Noronha Islands, an archipelago 355 kilometers off the northeast coast of Brazil.

Eleven aircraft and five ships are engaged in the search, including airplanes from France and the United States.

Earlier Thursday, a public interfaith service was held for the 228 victims at a 200-year-old Catholic Church in downtown Rio. Joining family members were members of the Brazilian armed forces, who are leading the recovery effort.

"Whoever has faith, whoever believes in God, believes in the eternity of the soul," said Mauro Chavez, whose friend lost a daughter on the flight. "This means everything."
