AUSTRALIA said yesterday that it was holding out hope that Malaysia Airlines Flight 370 would one day be found, as the last search of the seabed in the remote Indian Ocean where the plane was believed to have been lost was scheduled to end.

Malaysia said last week that the search by Texas-based company Ocean Infinity would end yesterday after two extensions of the original 90-day time limit.

Australian Transport Minister Michael McCormack said the four-year search had been the largest in aviation history and tested the limits of technology and the capacity of experts and people at sea.

“Our thoughts are with the families and loved ones of the 239 people on board MH370,” McCormack’s office said in a statement. “We will always remain hopeful that one day the aircraft will be located.”

Malaysia signed a “no cure, no fee” deal with Ocean Infinity in January to resume the hunt for the plane, a year after the official search in the southern Indian Ocean by Australia, Malaysia and China was called off. No other search is scheduled.

Australia, Malaysia and China agreed in 2016 that an official search would only resume if the three countries had credible evidence that identified a specific location for the wreckage.

Malaysia said last week that an Ocean Infinity ship Seabed Contractor operating underwater sonar drones had searched more than 96,000 square kilometers of sea. The search area deemed by experts to be the most likely crash site was only 25,000 square kilometers, roughly the size of Vermont.

The Boeing 777 vanished on March 8, 2014, while flying from Kuala Lumpur, Malaysia, to Beijing. The passengers on board the plane included 154 Chinese.  (SD-Agencies)
