Large objects detected in AirAsia wreckage hunt

AirAsia, which began operations in 2001 and quickly became one of the region's most popular low-cost carriers, said it was reviewing the suspension. The crash was the airline's first.

Strong currents and towering waves as high as 4 meters (13 feet) have slowed recovery efforts, scattering bodies and debris in all directions. The discoveries so far include an emergency exit door and slide, as well as a backpack with food and a camera inside.

As part of the investigation into the crash, autopsies will be carried out on some of the bodies, including the pilot and co-pilot, whose remains have not yet been recovered, said Budiyono, who heads East Java's Disaster Victim Identification unit and, like many Indonesians, uses only one name.

Generally, aviation experts say the more passengers, luggage and parts of the aircraft that remain intact, the more likely the plane hit the water in one piece. That would signal problems like a mechanical error or a stall instead of a midair breakup due to an explosion or sudden depressurization.

For family members, the wait has been agonizing, with local media covering every development and theory, many of which have proved to be untrue _ including a false report that a body was found wearing a life jacket, which would have indicated passengers had time to prepare for the impact or miraculously were able to put them on after hitting the water.

With more corpses arriving in Surabaya, some relatives said they were simply worn out. But they were encouraged by reports that parts of the plane had been detected and hoped that everyone on board would be retrieved.

"Let's hope the news is true," said Ongko Gunawan, whose sister was on the flight with her husband and their child. "We need to move on."

Vessels involved in the search for debris included at least eight sophisticated navy ships from Singapore, Russia, Malaysia and the US equipped with sonars for scouring the seabed to pinpoint the all-important black boxes and the wreckage.

A second US Navy ship arrived on Saturday to help in the search.

The hope, officials say, is that the body of the plane will still be largely intact, speeding the investigation.

"Many of the passengers believed to be still trapped inside the plane's fuselage and could be discovered soon," Supriyadi said. "God willing, we will complete this operation next week."
