Theory: Elinin's "break-up" is akin to the shuttle ditching it's solid rocket boosters!
If Elinin is a type of craft, it only makes sense that as it approaches it's final destination and begins to slow that it sheds it's outer hull and other waste products. Perhaps the boosters etc it uses would be harmful to our planet so they ditch them well away. So what we are seeing is not elenin breaking up, but the craft beginning to eject spent fuel containers and protective shielding. If this is true then amateur astronomers will soon be able to make out a shiny metal craft heading towards us.
