if this is indeed a part of mh 370, it's possible it could have drifted that far to the west with the two typhoons that went through during the search process, certainly it's possible especially if air was maintained in that piece of flight control surface there. so anything is certainly possible. >> mary if this debris does belong to mh-370 but they're still not ever able to recover the black boxes, could it be used to determine what brought the plane down? >> it's going to be very difficult this long in the water. lots of clues that might have been on it will have been erased by the saltwater and time but i think what it will be used for, if this is a 370, a 777, is they will go back and look at the search right at the inception and say if the plane was turning back and did not follow the arcs
