This question is directed to mathtalk-ga only:
What is the air-speed velocity of an unladen swallow?

Thanks for asking this very interesting question.  While searching
around the Internet for my favorite color, I came across this site:

[Hi, we're the Government and we're here to help]

So I'm going to go with ~45mph, an air speed that puts the swallows in
the upper echelons of fast fliers.

Thanks for your help!
