Between Hatton Cross and Hayes, fourteen miles west of central London, sits a piece of ground where someone takes off or lands roughly every forty-five seconds during daylight hours. London Heathrow Airport opened on 25 March 1946 as London Airport, on a site that had been a small airfield since 1930. Within a generation it had become the busiest international airport on Earth. It is still, in 2024 and 2025, the busiest in Europe, fifth in the world by total passengers, and second in the world by international passengers - Dubai recently passed it in the international category but trails it in connections. From above, the two parallel east-west runways are unmistakable: two grey ribbons cutting across the green fields of Middlesex, the four terminals strung between them, the great rectangular cargo zone to the south, the holding stacks where inbound aircraft circle in the sky above Buckinghamshire and Surrey, waiting their turn to descend.

In the 1950s, Heathrow had six runways arranged as a hexagram - three pairs at different angles, so that no matter which way the wind blew, at least one pair was within thirty degrees of useful. The permanent passenger terminal sat in the middle of the star. As jet aircraft grew ...

A Concorde could cross the Atlantic in three and a half hours - leaving London at 10:30 and arriving in New York at 09:25 local time, a fact that astonished travellers be...

Inbound aircraft are sent to one of these stacks, where they fly racetrack-shaped patterns at assi...

Heathrow Airport: Runway Alternation

Sun, 24 May 2026 00:00:00 GMT

Photo credit Citizen59, CC BY-SA 3.0. Heathrow runs in westerly-preferred operation most days, meaning aircraft take off to the west and land from the east, flying over London. This is the noisier configuration for passengers but the quieter one for residents under the approach path. To share the burden, the two runw...
