MH370 search to stop just short of Hardy’s predicted position

Two years ago Boeing 777 captain Simon Hardy calculated the most likely position of MH370’s undersea remains using only established facts and mathematics.

The Australian-led international search for the lost Malaysia Airlines 777, however, may be suspended in December just short of that position unless existing plans are amended.

Hardy’s proposed position, and the methodology that determined it, has been widely published, both in Flight International magazine in January 2015 and a month earlier on the web via

Most theories posted to the web – especially related to serious subjects like this – usually attract massive peer criticism and public comment, but Hardy’s has faced no criticism, just requests for clarification.

It has, however, attracted great interest, and he has met the Australian Transport Safety Board at their request more than once to talk about it.

He has now posted a spoken explanation of his methodology to YouTube, so if you want to test your mathematics and geometry, go there.

Hardy’s calculations put the resting position of MH370 just outside the planned area for the multinational search effort, close to its southern end. So the methodology that the official search team used produced results that are pretty close to the predictions Hardy reached independently.

Here is the ATSB’s explanation, posted on 21 September, as to why they will not look in Hardy’s predicted position even if the remainder of the planned search fails to find the aircraft:

“At a meeting of Ministers from Malaysia, Australia and the People’s Republic of China held on 22 July 2016, it was agreed that should the aircraft not be located in the current search area, and in the absence of credible new evidence leading to the identification of a specific location of the aircraft, the search would be suspended upon completion of the 120,000 square kilometre search area.”

The ATSB makes the intention clear: “It is expected that searching the entire 120,000 square kilometre search area will be completed by around December 2016.”

Hardy’s calculations put the MH370 wreck just outside that area, and they cannot be defined as “new evidence” because the ATSB knows about them already and has decided, without explaining why, not to search there.

By December the arrival of the southern hemisphere summer will have made the search much easier.

Hopefully the search team will find the aircraft remains within their planned search area. But what if they don’t?

If the ATSB won’t go there, Hardy is considering crowdfunding to extend the search for a few weeks into the area indicated by his work.



Latest phase of MH370 search gets interesting

On 3 November the Australian Transport Safety Bureau resumed the deep sea search for the lost Malaysia Airlines flight MH370 [but see update at end of story].

Refuelled, replenished and ready to go, the ATSB’s survey ship Fugro Discovery has arrived on station once more in the southern Indian Ocean (see footnote for an update).

For those seeking a reason to be optimistic following a discouraging 20 months of searching the ocean without a result, there is definite cause for renewed hope this time.

Since it began the search the ATSB has been scrupulously methodical, scanning the ocean floor within a long, slender curved rectangle that encompassed what became known as the “7th arc”. This is a long line on the earth’s surface established by vestigial radio responses from the fatal aircraft to Inmarsat satellites just as it was running out of fuel.

Theoretically the Boeing 777 could have come down anywhere close to it, but working with the aircraft’s last radar position the ATSB identified the arc sector where the aircraft could realistically have come down, and has searched almost all of the identified curve and its close vicinity.

Since it has now trawled almost all the 7th arc’s viable sector and not found the wreckage of MH370, there is not much more to search. Logic says they must be getting close.

But not only logic.

For those who doubted MH370 came down in the sea at all, the fact it did so was established in July when one of its flaperons was washed up on a beach on the Indian Ocean island of La Reunion. This fact was forensically confirmed more recently by the French air accident investigation agency BEA.

But there’s another reason for optimism: on 22 December last year Flightglobal published a mathematical/geometric calculation by Boeing 777 captain Simon Hardy, also a mathematician, which indicates precisely where, according to his calculations, MH370 came down.

The search sector that Fugro Discovery has just begun to trawl encompasses Hardy’s predicted position for MH370. His recent refinements to the aircraft’s final descent profile put it at S39 22′ 46″ E087 06′ 20″. He adds, however, that depending on how long the aircraft floated, the main wreck could have drifted some time before sinking, and even during the descent could have travelled laterally. At this location he would expect to see mainly “some moveable aerodynamic surfaces, like the missing part of the flaperon that we already have, and parts of slats and flaps and maybe even the RAT [ram air turbine].”

This could be said to be the last chance for the search under present estimated criteria, because 777 performance dictates that the aircraft could not have flown further than this extreme southern end of the 7th-arc-defined potential ditching area.

Anyone who has published material on the web knows that it may receive praise, but it will certainly receive criticism. The impressive fact about Hardy’s mathematics is that, despite hundreds of thousands of hits on the article containing his calculations, nobody has been able to blow a hole in them.

By 3 December Fugro Discovery expects to have completed the search of the area containing, according to Hardy’s calculations, the wreck of MH370 and the remains of those who went down with it.

Hardy says he says he is excited about the next month’s search, having invested more than a year of mental and emotional energy into working out where MH370 flew, and why. He wants it found.

He’s not alone.

LATE NEWS: On 5 November Fugro Discovery had to suspend the search and return to Fremantle, Western Australia, according to Australia’s Joint Agency Coordination Centre, because one of the crew developed suspected appendicitis.

UPDATE: Fugro Discovery was due to arrive back in the search area on 3 December.
