After an uncertain start at the beginning of the 20th century, aviation has grown to a size on a global scale. By the year 2000, over 100 million passengers traveled through the airports of large metropolitan areas, such as London. In the same year, there have been 35.14 million commercial departures worldwide, for a total of 18.14 million flight hours. Demand for commercial air travel has grown by an estimated 9% a year since the 1960s.
