The skies are full of vapour trails as jumbo jets criss-cross the sky again, repatriating refugees from Disneyland and carrying mange-tout from Kenya for a hungry nation! We are saved! It's a bit like Dunkirk and the Berlin Airlift all mixed together, really.
...by the way, there is a really good website called Flightradar24, where you can see what aeroplanes are flying in Europe and where they're going, and so on. And, in my case, you can then pop your head out of the skylight and see them in real life, and know that they are a Lufthansa Airbus en route from Dusseldorf to New York, or whatever.
