Consistent with CSIRO modelling
David Griffin, the CSIRO oceanographer who heads the MH370 drift model task force said the object that washed up on Reunion was consistent with CSIRO modelling. The agency had expected pieces of the aircraft to be found on nearby Madagascar.
Dr Griffin said the flaperon would need to have floated to Reunion, otherwise it would have sunk and got stuck.
He said the debris would not have any impact on the search area of the original crash because it was impossible to work backwards from where it was found due to too many variables.
Question as to whether debris in search area
Erik van Sebille, an oceanographer specialising in ocean currents who did extensive computer simulations last year of where Flight 370 wreckage might float, said that it was possible that some pieces might now be reaching Reunion, almost 5000 kilometres from the plane's last known location.
But the plane would have had to enter the water off north-western Australia, he said.
A series of separate analyses of the satellite "pings" coming from the aircraft's engines in its last hours of flight have all pointed to its coming down off south-western Australia, many hundreds of kilometres further south.
That is where investigators from Australia, Malaysia and China have concentrated their search efforts.
Currents in the Indian Ocean move fairly quickly from east to west near the equator, but those to the south move more slowly, Mr van Sebille said.
Debris entering the ocean in the primary search area would be much less likely to have drifted as far as Reunion by now.
Mr van Sebille said that, even if the object found on the shore came from Flight 370, that did not mean that any other parts of the plane would be found nearby.
"The way the ocean works is like a huge pinball machine [and the plane's wreckage] could be spread across an enormous area," he said.
