Surely on the plane trips you have made, you have heard the staff members talk strangely to each other. Employees of transport companies use speeches and special sentences in different situations not to be understood by passengers. These encrypted messages are also used to avoid panic in the aircraft. But if you are curious to learn their meaning, read below:

5 days in Denmark (5 days in Denmark)

Maybe you heard a stewardess on a plane saying "5 days in Denmark"? You might have thought that she was talking about vacations and not for a passenger.

This code is used by pilots and ship captains to signal a situation that is life-threatening. But in some places, firefighters, cops and some transport organizations use it as well. The code is always repeated 3 times in succession.
