(CNN) - Another day. Still nothing.
Australian authorities said Friday they had called off their search for the day for two mystery objects that may or may not be parts of missing Malaysia Airlines Flight 370.
Military surveillance planes, a commercial jet and two merchant ships combing the area failed to find any trace of the objects, which were spotted Sunday by a satellite in the treacherous waters of the southern Indian Ocean. The spot is more than 1,400 miles from the west coast of Australia.
Flight 370 vanished 14 days ago with 239 people aboard. The announcement Thursday by Australian officials that they had spotted something raised hopes of a breakthrough in a frustrating search that has yielded few clues about what might have happened to the plane after it stopped communicating with the ground, appeared to veer wildly off course then dropped out of sight for good.
As he had Thursday, Abbott warned again that the two objects may not be from the plane.
"It could just be a container that has fallen off a ship," he said during a visit to Papua New Guinea. "We just don't know."
On Friday, Hishammuddin Hussein, Malaysia's interim transportation minister, tried to reset expectations for a quick resolution to the mystery surrounding the plane.
"This is going to be a long haul," he said.
