swimming around the local public pool last summer ~ no other way to describe this other than a cubic flying shed ~ like you would have in yoru backyard - shiny / shimmering / changing shape about it self not unlike a crystal rubix cube. at high altitude - coming towards me on a 15° vector that then changes direction - instantly - and goes up and away in a complete different plane.

no possible way i saw what i saw.

except that i did see it.
