The archaeological lobby has succeeded in sinking an exhibit at the Sackler Gallery that would have given the American public an opportunity to learn something about early international trade routes in the Orient. See

The exhibit was supposedly sunk because the excavation work was not up to professional standards-- though one suspects that the real reason was to appease archaeologists who have little use for commercial salvers, whether contracted by a foreign government or not.
I've previously covered this dispute here:

Supposedly, the plan now is to "re-excavate the wreck" using AIA approved archaeologists no doubt. But money has to be raised first. Hopefully, taxpayer dollars won't be tapped for such project, but it will not surprise me if the US Government is ultimately expected to foot the bill for what probably is little more at this point than a vanity project.
