The A30, which is where yesterday's photo was taken runs by the perimeter of Heathrow Airport, and planes pass very close overhead. Sometimes, very close indeed. Hard as it is to imagine the area here used to be rural and the airport grew to meet London's air travel needs. One of the fun snippets of the history is that the original design, with terminals inside the runways, prevented much onsite carparking. When it was first built, air travellers were all expected to arrive with chauffeurs. Times have changed.
