Anyway, this picture shows the paths of the international incident between the US and Russian spacecraft. You know what they always say about crossing railroad tracks trying to beat a train through an intersection. Whack!
UPDATE: More information just keeps showing up about this. I just came across a video simulation of the collision. If this was cloud from a volcanic eruption (Google Alaska's Mt Redoubt) we would be getting some pretty sunsets! The chunks are most likely too small to be seen from the ground though, but who knows?
