On 3 November the Australian Transport Safety Bureau resumed the deep sea search for the lost Malaysia Airlines flight MH370.
Refuelled, replenished and ready to go, the ATSB’s survey ship Fugro Discovery has arrived on station once more in the southern Indian Ocean.
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.
