There are certainly going to be conspiracy theories for any happening that can't be easily explained, because they themselves are not easily explained or proven. MH370 will probably be popping up soon in Mauritania or Africa or maybe Russia, and everybody will be relieved and feel embarrassed to have thought there was any such things as aliens, or thoughts of hijacking or whatever. But still there does seem at this point, as they search for more debris around the flaperon site, that something in the whole scenario is missing. This little relatively tiny piece of evidence (possibly) is nothing compared to the bulk of the 777 as a whole, easily manipulated and relatively light in weight.It would, however seem that it had to be torn from the wing with great force and separated from other parts normally attached to it, such as the actuator, etc., most of which should float also. Where would the fuel tanks be, and the tubing and electrical lines be that were possibly routed through it?
