Missing airliner MH370 is “very likely” to be found if it lies in the undersea zone now being scoured, and is probably in good condition despite being submerged for 10 months, the Australian search chief told AFP.
Three vessels, with a fourth on the way, are probing the depths of the Indian Ocean off western Australia where the Malaysia Airlines plane carrying 239 people, mostly Chinese, is believed to have crashed.
The jet disappeared en route from Kuala Lumpur to Beijing on March 8 and apart from some mysterious satellite “pings” interpreted as plotting its southern course, no sign of it has been found despite a massive air and sea operation.
Relatives of those on board have endured a long wait for answers on what happened to their loved ones, with their torment reawakened by AirAsia Flight QZ8501 crashing into the sea off Indonesia on December 28.
So far, one quarter of the priority underwater search area of 60,000 square kilometres (23,166 square miles) has been checked, while a wider zone of 208,000 square kilometres has been mapped.
“Our satellite calculations gave us an area we determined was high priority,” Martin Dolan, the chief commissioner of the Australian Transport Safety Bureau, which is leading the search, told AFP.
“In this 60,000 square kilometres, it’s very likely we will find the aircraft, but we don’t know exactly where. We just have to cover that area thoroughly until we find the aircraft.”
The priority search began in early October and will accelerate over the next few months as weather conditions improve, with the hunt expected to wrap up in May.
If the jet is not found, a decision on extending the investigation would be made by Australia and Malaysia, which have jointly shouldered the cost.

Dolan said mapping had led to the discovery of previously unknown undersea features such as mountains, volcanos, chasms and a rough, uneven sea floor, highlighting the challenges.
To take a closer look at the complex terrain, the Australian and Malaysian governments said Wednesday they were jointly funding the fourth ship, Fugro Supporter, to join the probe later this month.
While the other three vessels — Fugro Equator, Fugro Discovery and GO Phoenix — use sophisticated sonar systems attached to tow cables up to 10 kilometres (6.2 miles) long, the Supporter will have an autonomous underwater vehicle.
“(It) can be programmed and cover areas much more thoroughly. It’s of course a lot slower,” Dolan said, adding that about five percent of the search area needed the closer scrutiny.
“We need to go slow so that we can be 100 percent sure that we have covered that area totally.”
