So did we ever find out what the actual airspeed velocity of an unladen swallow is? And do coconuts migrate?

The answer is blowing in the wren.

Coconuts certainly migrate. They migrated from South America to Polynesia.

I believe the OP is thinking about the immortality of the crab ;).

lol I can't type. No further message...

These are the questions that have been pondered since the beginning of time

If you were flying over your house in a canoe and all 4 wheels fell off....

The question I was trying to type before having a major PEBKAC malfunction, was are you referring to the airspeed velocity of European or African swallows? Not that I have a definitive answer, of course, just curious.
