In Airport Live, Dan Snow, Dallas Campbell and Anita Rani go airside at Heathrow, the world's busiest international hub airport.
The first of four programmes shows air traffic control in action and explains the extraordinary science and logistics behind every flight.
Dan is based at the heart of the airport, the air traffic control tower, giving an eagle's eye view of the complex choreography of landings, departures and ground movements. He finds out how Heathrow went from a row of tents to an international powerhouse welcoming 70 million passengers a year.
Anita discovers how weather affects the airport each day, not just when it snows; and Dallas looks at first class on the A380, the world's largest passenger jet.
