The continuing mystery over the fate of Malaysia Airlines Flight 370 and the 239 people on board is "almost inconceivable", a new report has said.

But the Australian Transport Safety Bureau's final report on the search, which was abandoned in January after almost three years, concedes that authorities are no closer to knowing the reasons for the plane's disappearance, or its exact location.

This is despite last year's narrowing down of its most likely resting place to a 9,650 square mile (25,000 sq km) patch of the southern Indian Ocean.

The Boeing 777 carrying 227 passengers and 12 crew disappeared soon into its flight from Kuala Lumpur to Beijing on March 8 2014.

A 52-day surface search covered an area of several million square miles in the Indian Ocean west of Australia, before an underwater search mapped 274,000 square miles (710,000 sq km) of seabed at depths of up to 20,000ft (6,000m). They were the largest aviation searches of their kind in history, the bureau said.

Despite other methods such as studying satellite imagery and investigating ocean drifts after debris from the plane washed ashore on islands in the eastern Indian Ocean and the east coast of Africa, the 1,046-day search was called off by the governments of Malaysia, China and Australia on January 17.

"The reasons for the loss of MH370 cannot be established with certainty until the aircraft is found," the bureau, which co-ordinated the search, said in the 440-page report.

"It is almost inconceivable and certainly societally unacceptable in the modern aviation era, with 10 million passengers boarding commercial aircraft every day, for a large commercial aircraft to be missing and for the world not to know with certainty what became of the aircraft and those on board," it said.

"The ATSB expresses our deepest sympathies to the families of the passengers and crew on board MH370. We share your profound and prolonged grief, and deeply regret that we have not been able to locate the aircraft, nor those 239 souls on board that remain missing."

However, the report said the understanding of where the plane may be is "better now than it has ever been", partly as a result of studying debris that washed ashore in 2015 and 2016 which showed the plane was "not configured for a ditching at the end of flight", meaning it had run out of fuel.

The search team also looked back at satellite imagery which showed objects in the ocean that may have been MH370 debris. The report said this analysis complemented work detailed in a 2016 review and identified an area of less than 9,650 square miles (25,000 sq km) - roughly the size of the US state of Vermont - that "has the highest likelihood of containing MH370".

The bureau noted that the Malaysian government is "continuing work on their investigation of the facts and circumstances surrounding the loss of MH370".

The search was extremely difficult because no transmissions were received from the aircraft after its first 38 minutes of flight. Systems designed to automatically transmit the flight's position failed to work after this point, the report said.

Subsequent analysis of radar and satellite communication data revealed the aircraft had continued to fly for seven hours. Its last positively known position was fixed at the northern tip of Sumatra by surveillance systems operating that night, six hours before it ended its flight in the southern Indian Ocean.

The bureau said the search had at least led to some important gains in the field of locating missing aircraft on flights over deep ocean areas, with improvements made to systems for tracking aircraft.

"Steps are being taken to advance other aircraft systems including emergency locator transponders and flight recorder locator beacons," the report said.

ATSB Chief Commissioner Greg Hood praised the commitment of everyone involved in the search.

"This was an unprecedented endeavour and there has been an extraordinary response from the global community," he said in a statement.
