 Joe, thank you very much indeed. News breaking that now 1,400 flights have been cancelled around the world. This is not just disrupted, these are flights that are not happening. Interestingly, the vast majority of them are in the US. We've known that the big US airlines grounded their flights for a while, but of the 1,400 flights reported cancelled around the world, over 500 of them are in the US, where it's been night time and people are just beginning to start waking up.
