The episode revealed the deadlines that Heathrow works to, enabling an average of 190,000 passengers a day to travel through the airport. Viewers were given unprecedented behind-the-scenes access to the daily relay race first-hand with a guided tour by Simon Newbold, Heathrow's Airside Operations Manager.
The programme also showed air traffic control in action with NATs managing an arrival or departure every 45 seconds. The BBC team, based at the heart of the airport in the air traffic control tower, gave viewers an eagle's eye view of the complex choreography of landings, departures and ground movements.
The episode also revealed how Heathrow went from a row of tents to an international powerhouse welcoming 70 million passengers a year. Paula Abbott, one of Heathrow's Airside Duty Managers then gave viewers an overview of how weather affects the airport each day, not just when it snows.
Finally, the program went onboard an A380, the world's largest passenger jet, to explore Singapore Airline's first class service.
