I think @electrycmonk was hoping that you would know that his question was a quote from Monty Python & the Holy Grail.5. Measuring the airspeed velocity of an unlaiden swallow would depend on the species and size of the bird, as well as the environmental conditions, among other factors. Would you like me to provide more specific information?
Now that you know this, if someone asked, " What is the air speed velocity of an unlaidened swallow?", how would you answer?
