Wolfram Alpha Can CROSS THE BRIDGE OF DEATH!!

[Ian David]

Assuming estimated average cruising airspeed of an unladen African swallow | Use estimated average cruising airspeed of an unladen European swallow instead http://tinyurl.com/qx6ahd

<snip>

Input interpretation:
estimated average cruising airspeed of an unladen African swallow
Result:

there is unfortunately insufficient data to estimate the velocity of an African swallow (even if you specified which of the 47 species of swallow found in Africa you meant)\n(asked of a general swallow (but not answered) in Monty Python\'s Holy Grail.)
