MH370 search: Too early to tell whether debris on Runion Island is part of missing jet

It's too early to tell whether debrisfoundonRunion Island Wednesday could be part of the wreckage ofMalaysia Airlines Flight MH370, which disappeared off the coast ofMalaysia inMarch 2014, and whose mysterious fate has been the source of much speculation and consternation.

"People are getting ahead of themselves over this," saidEric Chesneau, an officer with the air transport police of the French Indian Ocean territory, in response to speculation on social media. "It is more than likely plane debris, [but]we don't know what exact part it may be."

Speculation was rife onlineWednesday that debristhat washed up in the town ofSaint-Andronthe northeast coast of theFrench island, about 1,000 km east ofMadagascar, was part of a wing ofa Boeing777 jet, the same kind of plane asMH370, but no one has officiallyconfirmedthat detail.

An unnamed U.S. official told The Associated Press that air safety investigators, including one from Boeing, have a "high degree of confidence" that, based on the photos, the piece of debris is a wing component unique to the Boeing 777.

Local radiostationRTL Runion reported that a two-metre long piece of plane debris was found by a local group that clears trails along the coastline. The debris had some kind of identifying codeon it,the stationreported, which might make it easier to identify, and people who saw it up close saidit was covered with shells.

"We've received some pictures of the item, and we are having them assessed by the manufacturers as to what they may be," Joe Hattley, a spokesman for theAustralian Transport Safety Bureau, which is leading the search for MH370, told Australian Associated Press (AAP).

"The French authorities have it secured.We'll work with the French.First, we need to determine what the item is and whether it is part of a Boeing 777 and then if it is part of MH370."

Reuters reported that France's air crash investigation agency,Bureau d'Enqutes et d'Analyses, is studying the debris.

Hatleytold AAP thatinvestigators will be looking for a part number and a serial number that could possiblybe matched to a specific aircraft frame.

"Similar parts on different planes would have a number," he told AAP. "And you'd have a serial number, a specific number to that particular component."

Theories on source of debris

The most recent crash that occurred near Runion happened onMay 5,2006, when a twin-engine plane crashed into the ocean across from the Pierrefonds airport on the southwest coast of the island, RTL said.

Another possible source of the debris could be the2009 crash of YemeniaFlight626, which went down on its approach to Comoros,an archipelagooff the northwest coast of Madagascar.

Grard Feldzer, a former Air France pilot, told the Libration newspaper that it's impossible to say anything conclusive based on the photos and that analyseswill have to be done on the metal and paint to determine the age and other details of the aircraft it came from.

If the debris were to be traced toMH370, it would be the first sign of the passenger aircraft since it disappeared in March 2014.

Exactly what happened to MH370 has never been established, and no trace of thewreckage has beenfound despite millions of dollars spent searching for the plane.

Flight MH370took off fromKualaLumpur, Malaysia,on March 8, 2014,at 12:41 a.m. local time headed for Beijing. Less than a half hour into the flight,air-traffic control on the ground lost contact with the jet, and less than two hours into the flight, itdisappeared from military radar, although it continued to send data to a satelliteuntil 8:11 a.m. Malaysia time.

The plane was carrying 227 passengers, most of whom were Chinese, and 12 crew.

When it disappeared from radar, it washeading west across the Strait of Malacca the opposite direction from where it was supposed to be flying, leading experts to conclude that it veered from its intended flight path, turned around and flew back across the Malaysianpeninsula toward the Indian Ocean.

No closure for relatives of victims

Authorities initially focused the search for the plane on the South China Sea, the Straits of Malacca and the Andaman Sea but later shifted their attention much farther south to the remote southern Indian Ocean after the satellite telecommunicationscompany Inmarsat released data that suggested that's where the planewent down.

The southern Indian Oceansearch has been co-ordinated primarily by Australia, although Malaysiaand China have also contributed funds and resources, and several other countries have lent expertise and equipment.

To date, the searchhas costmore than $100 million and extended across tens of thousands of square kilometres.

This spring,the search area wasexpanded beyond theoriginal 60,000 square kilometresto enable up to 120,000 square kilometres to be searched. More than 55,000 square kilometres of theseafloorhave been searched so far, according to the Australian Transport Safety Bureau, and the search will continue throughthe winter months in the Southern Hemisphere.

In January of this year, the disappearance of the jet was officially declared an accidentandall people on board werepresumed dead in order to facilitate compensation for the victims' families.

A comprehensive report into the disappearance found no significant anomalies in the flight, except that the battery of the locator beacon for the plane's data recorder had expired more than a year before the jet vanished.

That still does not explain what caused the plane to veer so off course in what has become aviation's biggest mystery that continues to confound experts and investigators alike. At the same time, the relatives of the dead have got no closure, and many still believe that their loved ones may be alive amid a host of conspiracy theories including one that the plane was hijacked and landed somewhere safely.

The case of the missing jet has prompted many comparisons withAir France Flight447, which crashed en route to Paris fromRio deJanieroin May 2009 with 228 people on board andwasn't found until two years later, but the key differencein that case was that searchers found some debris and thebodiesof several victims of the crash days after the plane went down, helping narrow the search.
