As fog blanketed parts of the country, this amazing photograph was tweeted by passenger Sarah Wells as she flew into London, showing the skyline of our engulfed capital.

“Flew into foggy London. Views are beautiful-this is the Shard and all the towers in the city.”

Like in the pea-soupers of old, the swarming masses below are hidden in cloud and vulnerability.  Stephen King’s The Langoliers comes to mind.

Hopefully everybody was still there when the plane landed.
