First they say that they didn't announce this one right away because they didn't want to scare people like in the past where additional calculations showed that there is not a chance of an impact..... and then a few days later "Whoops, never mind!" again.
Oh, well.... I'd rather that it be a false alarm again rather than finding out that they confirmed it will hit. Besides.... in 2029 I'll only be 59.... that's too early for me to exit!
