When thinking about advanced in aviation, wind-tunnels are a necessary step. The cost of disaster is simply too high not to test extensively before deployment. It is a world far removed from the common software development lifecycle.

Oobject shows some fine examples, including one from the Wright brothers:

The interior and exterior of wind tunnels have unusual design requirements that often make them accidental architectural masterpieces.

Test environments as masterpieces? I like the sound of that. Perfect material for presentations to developers who scoff at the idea of testing.
