Talking of darkness, there was apparently a major power blackout across Europe last night, centred on Cologne in Germany. Given that's precisely where I was at the time, and furthermore, that I returned on a 10am flight with only 30mins delay, and only found out about it once I'd got back to the UK suggests either that I am, truly, the least observant person the world has ever seen, that the Germans know how to handle a crisis, or that I'm actually going mad. I shudder to think what effect such an event would have had on British transportation.
