For most people living in the United Kingdom, the 10 days between the 8th and 19th of September passed in a blur. On the evening of Thursday 8th of September it was announced that the Queen had died. There was a well-prepared plan for this eventuality known as Operation London Bridge, covering everything from the announcement of her death, through the mourning period to the state funeral. It was developed in the 1960s and frequently revisited. There are similar plans for other royals.
