Flaperons are usually found on the trailing side of the wing of an aircraft liner, they are used to help in banking and rolling the aircraft (aviation jargon for turning an aircraft midair). Flaperons are for usually on lower speeds and in midflight.
Most aviation experts are sure about one thing- the particular chunk that has currently landed up should belong to a liner. The picture above is from a Boeing manual that shows it aligns perfectly with expert opinions. Notwithstanding the idea that of the many Boeing 777 crashes, only one has been (presumed to be) in the South Indian Ocean and furthermore the fact that of all 777s currently in operation or otherwise only MH370 has been unaccounted for in the aviation log books.
So how does a piece, that is literally microscopic when compared to the vastness of the oceans land up on the shores of an island the size of a pea? The answer to that would lie in the oceanic currents. With the supposed crash zone about 1100 kilometres off the Australian coast in the South Indian Ocean, currents would have to carry it north, then due east and further south, moving counter clockwise as do gyres in the major oceans of the world. The West Australian current would lead it into the South Equatorial current than would eventually land it up along the coast of one of the islands that dot the south eastern coast of Africa or mainland Africa itself. If Madagascar were perpendicular, rather than parallel to the current flow, in all probability we could have found more debris than the scattered couple of pieces found thus far.
The flaperon piece was flown to Toulose, France where Airbus Industrie is headquartered in this massive search operation that has spanned all major aviation powers in the search for answers. Australia, for its part says the part being found in La Réunion is a confirmation that the plane went down in the region around the current search area in the South Indian Ocean.
Well one thing could be for sure: the end of the prophetic conspiracy theories regarding the demise of the ill fated jet liner than took along with it 239 souls into their watery graves.
