Flyby during the Fiesta Nacional de España, the national day of Spain. The fiesta commemorates the day that Christopher Columbus (an anglicized version of Cristoforo Colombo, though after being adopted by Spain from Italy he called himself Cristóbal Colón anyway) landed in the Americas.

Columbus celebrations are held for the same purpose across the Americas, though they are not always whole-heartedly supported. Indigenous people in particular are likely to feel a little irritated by the suggestion that their land was "discovered".

In Madrid, the King of Spain and Presidente oversee a military parade that lasts around two hours. Go and see it if you like tanks.
