Debris found in the India Ocean over the weekend doesn't belong to missing Malaysia Airlines Flight 370, officials said Monday. Turns out it was just some old fishing gear.
Despite the setback, Australia's Prime Minister Tony Abbott is pledging the search for the plane will continue.
"This is an extraordinarily difficult exercise. We are searching a vast area of ocean and we are working on quite limited information," Abbott said.
He added that the best brains in the world and all the technological mastery is being applied to the task.
"If this mystery is solvable, we will solve it," he said.
It's now been more than three weeks since the plane disappeared after 239 people were on board. Abbott said he has no plans to stamp a time limit on the search.
"We owe it to everyone to do whatever we reasonably can and we can keep searching for quite some time to come. And, as I said, the intensity of our search and the magnitude of operations is increasing, not decreasing," he said.
Malaysian officials say radar shows the plane went down in the India Ocean, but families of the missing want some sort of proof.
Malaysian Prime Minister Najib Razak plans to travel to Perth on Wednesday to see the search operations firsthand, according to the Associated Press.
