Trivia: When does the Union Jack fly over Buckingham Palace?
On national holidays
When the country mourns
When the queen isn’t there
At the changing of the guard
The correct answer is When the queen isn’t there
So why is this answer correct? : The Union Jack is the national flag of the United Kingdom, but a different flag usually flies over Buckingham Palace: the Royal Standard, representing the U.K. sovereign. The Royal Standard follows the queen when she travels, so while she’s away from Buckingham Palace, the Union Jack flies in her absence.
