Modern airliners do a good job of flying automatically until something unexpected happens. At that point, a pilot takes control and typically resolves the problem with no drama or fanfare.

As powerful as computational fluid dynamics and supercomputing are, they have not come close to relegating wind tunnels to history. In fact, in the U.S., a new tunnel is going up at MIT, and NASA is deliberating whether it should close a historic tunnel at NASA’s Langley Research Center in Virginia four years from now as planned.
