Interesting fact:

English is spoken by 1,500 million people worldwide and it is the official language of 67 countries. Did you know that is also the language of the skies? English is spoken by all airline pilots – this means that pilots flying anywhere in the world can communicate with one another. They even have their own vocabulary! The term ‘deadheading’ is used when a pilot must take a flight as a passenger to get to where his own plane is stationed.
