How Heathrow went from six runways to two
Chocks away Rachel Reeves backed a third runway for Heathrow, reigniting a debate which has been going on for years. Yet Heathrow, when originally laid out in 1946, had six runways varying in length between 5,300 and 9,200ft: three pairs of parallel runways running east to west, north-west to south-east and north-east to south-west. As aircraft grew larger, there was less need for them to take off and land in alignment with the wind, but there was a need for longer runways. Heathrow gained its current layout in the 1970s when the east to west runways were extended to more than 12,000ft each, and three of the other four runways closed.
