KUALA LUMPUR: The families of Malaysia Airlines flight MH370 passengers have welcomed with renewed hope the announcement of a new search for the aircraft, which disappeared more than 10 years ago in one of the greatest mysteries in aviation history.

Flight MH370, a Boeing 777 with 239 people on board, went missing en route from Kuala Lumpur to Beijing in 2014.

The search became the most expensive operation in aviation history but ended inconclusively in 2018, leaving the families of those on board still haunted by the tragedy.

On Friday, Malaysia’s Transport Minister Anthony Loke announced that he hoped to “give closure to the families” as the government agreed to allow private contractor Ocean Infinity, which was the last to try to locate the plane, to resume search efforts.

He told reporters that the operation would focus on a new area spanning 15,000 sq. km in the southern Indian Ocean — a development raising hope among relatives of passengers and crew aboard flight MH370.

“The significance of this renewed search cannot be overstated. For the families of passengers, the scientific community and global civil aviation safety, it offers renewed hope for long-awaited answers and closure,” Voice 370, the association representing them, said in a statement.

“We, the next of kin, have endured over a decade of uncertainty, and we hope that the terms of the renewed search are finalized at the earliest and the decks are cleared for the search to begin.

“We continue to hope that our wait for answers is met.”

Ocean Infinity, the private underwater exploration firm that will undertake the $70 million search, was briefly involved in the 2018 efforts after a three-year operation covering 120,000 sq. km of the Indian Ocean failed to locate the aircraft and was suspended in 2017.

The new agreement was met on a no-find, no-fee basis, meaning that Ocean Infinity will be paid only when the wreckage is found.

“We are encouraged by Ocean Infinity’s readiness to deploy their advanced fleet, including sophisticated vessels, AUVs and cutting-edge imaging technologies,” Voice 370 said.

“We gather that the company has followed this up with thorough due diligence, analyzing all available data, and alternative scenarios proposed by independent researchers and recommendations on potential search areas.”

Flight MH370 took off from Kuala Lumpur in the early hours of March 8, 2014 and lost communication with air traffic control less than an hour later. Military radar showed the aircraft had deviated from its planned path. It remains unclear why that happened.

Many conspiracy theories have emerged to explain the aircraft’s disappearance, ranging from suspicions of the captain’s suicide to concerns over the 221 kg of lithium-ion batteries in the plane’s cargo, as well as the involvement of passengers, two of whom were found traveling on stolen passports.

When the probe was suspended, Kok Soo Chon, head of the MH370 safety investigation team, told reporters in July 2018 that his team was “unable to determine the real cause for disappearance of MH370” and “the answer can only be conclusive if the wreckage is found.”
