Covering five square miles and processing nearly 200 000 passengers each day, Heathrow is one of the busiest and most complex airspaces in the world. Two runways cope with 1200 aircraft every day while a 76 500 strong workforce helps keep Heathrow moving.

From air traffic control to airport hangars, presenters Kate Humble, Dallas Campbell and Anita Rani follow aircraft from the moment they enter Heathrow’s airspace to the moment they depart.

With unprecedented access to the people and processes that make air travel possible, this series follows the airport as it works against the clock to keep planes on time, passengers moving and manage the impact of constantly changing weather conditions.

From the complex choreography of air traffic control, to how to fly the world’s largest passenger jet, the A380, Airport 24/7 is a journey through the skies and a definitive account of modern air travel.

Airport 24/7 airs from Wednesday, 1 October at 21:00 on BBC Knowledge, channel 184 on DStv.
