Although ive been tracking this thread very regularly! I may of missed this question answered.
What about these image findings via sat, they are 4 days old, im sure daily images from this area have been rescanned? Which would indicate with current drift approximations more debris or potentially finding the same? But nothing more recent has been published anyway.
Either that or now due to currents/weather nothing is left afloat which means it was an awful amount of effort to find nothing.
