An American scientist who led the search for wreckage after the Air France crash in 2009 say time is running out to find the missing Malaysia Airlines plane.

Colleen Keller, who helped scour the Atlantic Ocean for flight AF447 after it disappeared en route from Rio de Janeiro to Paris, said identifying the search area was a major challenge.

She fears the chances of doing the same for the Malaysian airliner are now dwindling.

“We’re going to need some significant leads to find it,” Ms Keller, who worked as an analyst for Metron, a scientific consultancy for the US Navy, said.

“I think the search area is so big. I’m certainly hoping the criminal investigation will yield some motives that will steer us in the right direction.”

The breakthrough in the Air France investigation came when US underwater drones discovered the wreckage of the aircraft off the coast of Brazil.
