What is the air-speed velocity of an unladen swallow?
The question of the air-speed velocity of an unladen swallow comes from the movie Monty Python and the Holy Grail. In the movie, it's used as a humorous and nonsensical question.

Now, to answer the question:

Swallows are small birds that are known for their fast flying. If we're talking about real-life swallows, studies have suggested that the air-speed velocity of an unladen European Swallow (meaning it's not carrying anything) is roughly 11 meters per second, or about 25 miles per hour.

There are different types of swallows around the world, and their flying speeds can vary. European Swallows and African Swallows, for example, might have slightly different flying speeds due to differences in size, wing shape, and other factors.

But remember, the question from the movie is mainly a joke and wasn't intended to be a serious inquiry into bird aerodynamics!
