anyone think amelia earharts plane will ever be found? i know its been decades...but do you think there is a chance?

I do not know if it has definitely been found, but I would ask whether by chance (e.g. during cable-laying or a geological sea-bed survey) or deliberate search.

If the latter, why?

If her aeroplane is ever found definitely, it should be left undisturbed, its location not revealed, as Amelia Earhart's grave.
