«Royal Household of the United Kingdom - The Royal Household in the modern era». Encyclopedia Britannica(engelsk). Besøkt 8. november 2020. «The last of the great officials of the household is the master of the horse, but that position is now almost entirely ceremonial. The crown equerry is in charge of the royal mews and of ground travel in its widest sense (with the exception of rail travel, which is coordinated with the Royal Travel Office). One of the extra equerries, for instance, was responsible for air travel, a service instituted by King Edward VIII on his accession to the throne. The royal family’s air transport needs are now directed by the lord chamberlain’s office.»
