Cream/white Boeing with no markings just landed

I did some digging before I posted - One of those vision airlines unmarked jobs just landed on Cape Cod at 1820. And it was blocked no data was shown or available.

This is about the fourth or fifth time it has been in recently. Any ideas?

If that was Vision Airlines they have a long and sordid history. I assume the registration number is still on the plane. They went from a small charter, to a scheduled airline, back to a charter in the space of a couple of years. They were sued by Florida for collecting and not turning over airport fees. Who knows what else.
Maybe it was a charter you saw.
