Yesterday, kept seeing those faux-handwritten signs that the Evening Standard give to newspaper sellers to improve their sales (er, adverts, I think they're called) that said: SPACE ROCK ON COLLISION COURSE WITH EARTH.
Sounded kinda scary to me, but people were just carrying on their everyday business. Turns out it's not due till 2019. So, no rush then. And of course, it could be delayed if it forgets to change at Crewe.
