Flash animations were terminated by Adobe in 2020 so no longer work as intended on this page. I have included stills instead.
In the airspace above London there can be as many as 10,000 people aloft at any one time. I often go out early in the morning and see, to the South of London and along the Thames Estuary, the 'stacks' of planes and their occupants circling around waiting to land.
In this piece the planes and the buildings of the city flash friendly greetings to each other - a babble of radio noise filling the air between. Empty foyers and a still sleeping city await their arrival.
