Wind tunnel testing is necessary in order to validate the results.  Remember Microsoft's Excel math mistakes?  If an error like that crept into CFD calculations, the results could get "interesting".

This makes sense, Beth. Wind tunnels are both time-consuming and expensive, aren't they?

Beth, this is where CAE codes make a big difference.  It is possible to explore a large part of the design space in the computer.  This gives the design team the ability find optimal, or near optimal, parameters for their rel-world testing.

Another interesting aspect is the cloud for CFD.  These are highly parallel simulations that seem more amenable to massive parallel solutions.  It is also interesting to see that this is a public cloud solution.
