Heathrow airport is busy! Although not the biggest in the world it still deals with over 78 million international passengers per year. Unlike the purpose-built airports popping up all over Asia, with their seemingly unlimited space, Heathrow grew from a little 1929 airfield, 14 miles west of central London.
Heathrow airport only has two runways but these deal with an amazing 1,300 combined take-offs and landings each day.
