Queen Elizabeth has to go through security when she leaves the country.
The 91-year-old monarch - who has travelled to 120 countries during her reign - doesn't need to have a passport when she goes abroad but she must still have her identity checked every time she enters and leaves Britain.
For the past eight years, the queen has had to provide her full name age, address, nationality, and place of birth before she's allowed to board her plane.
According to the Mail Online, the details she provides when going through boarder control at the airport are "checked against terrorist and criminal watch lists.
The Royal website states: "As a British passport is issued in the name of Her Majesty, it is unnecessary for The Queen to possess one."
However, although the monarch doesn't need to have a passport to travel, the rest of the royal family - including Prince Charles and Philip - must have one.
As well as her planes, the queen also has a fleet of electric vehicles, and recently added an eco-friendly van to transport plants and machinery to her collection.
A spokeswoman said: "The gardening team will shortly replace their existing vehicle with an electric van. An application has therefore been made to introduce a charge point in the Long Shed at the back of Buckingham Palace.
"This vehicle will be used for transporting machinery, plants and personnel."
Elizabeth is also the proud owner of three other green cars, a Renault Twizy - gifted to her in 2012 - a BMW i3 and a hybrid 7-Series.
The spokeswoman added: "The Royal Household has had two fully electric cars, and one hybrid, for official use by the Royal Mews for several years.
"There are two existing dedicated charging units for these vehicles, at Buckingham Palace and Windsor Castle."
