Heathrow: Britain's Busiest Airport

This episode follows Heathrow staff racing against the clock to process thousands of passengers arriving from 84 different countries. Airside Safety Officer Glenn and his colleagues work closely with Air Traffic Control to keep Heathrow’s two runways open and clear of debris. Meanwhile, staff from the Animal Reception Centre welcome a variety of weird and wonderful animals – from pet ferrets to a wild tiger. Inside the terminals, Heathrow staff deal with passengers including a man who is stuck living at the airport after being deported from Thailand, and a family whose young relatives have got lost in Arrivals.
