What is the air-speed velocity of an unladen swallow?
The air-speed velocity of an unladen swallow depends on several factors, including the species of the swallow, its size, and the weather conditions. However, there is a famous question about the air-speed velocity of an unladen African Swallow, which was featured in the movie Monty Python and the Holy Grail.

In the movie, the character King Arthur is asked this question by the Keeper of the Bridge of Death. After some back and forth, the Keeper specifies that he is referring to an African Swallow, and King Arthur responds that he doesn't know the answer.

In reality, the air-speed velocity of an unladen African Swallow is estimated to be around 11 meters per second or 24 miles per hour. However, this is just an average and can vary depending on various factors. It's worth noting that the question in the movie was meant to be humorous and was not intended to be taken seriously.
