Good find. The sky isn't falling but it has slipped a bit more. Odds are now greater than a Clinton confession. The good news is the appropriate scientists are paying attention to this and considering contingencies. The rest of us need do no more than add this to the end of our prayers for the next 8 years. Sounds like we'll know more by then than I'd hoped. Then we either get to forget about Apophis or move it to the top of our prayers. And watch the rest of the world look for America to save them, again. At least that would wipe global warming and a bunch of other bunk off the front pages. Not to mention real problems merely the scope of Katrina or the Tsunami. It might even be enough to resume
Project Orion research as a backup option. A little fallout doesn't sound so bad compared to a great big sure fall down.
