French prosecutor: 'Certainty' that the wing is from MH370

The airplane debris found on Reunion Island in July belongs to Malaysia Airlines Flight 370, a top French prosecutor was quoted by French media, Thursday.

Investigators learned Thursday that a series of numbers found inside the plane flaperon matches records held by a Spanish company that manufactured portions of the component, linking the debris to MH370, the office of Paris Prosecutor Francois Molins said.

Days ago, "Le monde" quoted a “close source” who said that experts participating in the analytical work could not conclude definitively that the piece found is a part of the wing belonging to the missing plane.

It added that according to the information provided to families at the beginning of the investigation, experts have not found the license plate of the piece. However the newspaper added that the “scenario of no is more improbable than yes.”

Meanwhile, the Associated Press said that the deep sea hunt for the missing Malaysia Airlines jetliner will likely include cutting-edge sonar equipment when it ramps up again in October after the stormy southern hemisphere winter has passed, the Australian search leader said on Wednesday.

The Australian Transport Safety Bureau, which oversees the recovery operation on Malaysia's behalf, has been criticized by some deep-sea salvage experts for not choosing synthetic aperture sonar, or SAS, from the outset of the search for Flight 370 that began far off the west Australian coast in October last year.
