To take to the sky like a bird on the wing, it's been a dream of mankind ever since there was a "mankind". Our ancient ancestors marvelled at birds and other flying creatures and longed to be above it all with them. Nowadays, flying is a very commonplace form of travel. So it's not surprising that some of the phrases and jargon used on aircraft have made their way into our more common lexicon of terms and phrases. 

Like most industries, the airline industry has its own unique phrases and terms. To industry insiders, it's no big deal. To those of us who only use an airplane every now and then it certainly sounds like they are talking about secret and clandestine stuff.

Many of the phrases and terms are used simply for logistics. The phrases allow crew members to efficiently and succinctly communicate with each other without drawing the unintended attention of passengers.
