Edit: Additionally, that’s about 63½ European swallows, assuming an average weight of 5 ounces. Given that a European swallow must beat its wings 43 times per second to maintain airspeed velocity, it’d be a proper racket.

Those numbers are from monty python and the holy grail and are very wrong. I am spreading misinformation online.
Somewhere between 150 and 160, depending on the tennis balls. Hope this helps

And if it’s an African swallow?
Not covered in the film and I refuse to get my information anywhere other than Monty Python. The mass of an african swallow is therefore unknowable.
It’s a fair cop
