PERTH, Australia - Despite what Australia called an "intensifying search effort," an international hunt today by aircraft and ships in the southern Indian Ocean found no debris linked to the Malaysian jet that vanished more than three weeks ago.
Several dozen angry Chinese relatives of Flight 370 passengers demanded "evidence, truth, dignity" from Malaysian authorities, expressing their frustrations at a hotel near Kuala Lumpur as the mystery drags on.
Nine aircraft and eight ships searching the waters off western Australia found only "fishing equipment and other flotsam" not connected to the Malaysia Airlines plane, the Australian Maritime Safety Authority said. The Boeing 777 disappeared March 8 while flying from Kuala Lumpur to Beijing with 239 people aboard.
But at least four orange objects that were more than 2 meters (6 feet) in size were seen by the crew of an Australian P3 Orion search plane, said the pilot, Flight Lt. Russell Adams, after returning to base.
"I must stress that we can't confirm the origin of these objects," he said, adding that images of the items have yet to be verified, and a GPS buoy was dropped and ships must still investigate.
Adams said it was "the most visibility we had of any objects in the water and gave us the most promising leads."
