It may be that computational capacity has become cheap and powerful enough that private companies can easily afford to do their own calculations. However, I'm from the old school, and still think that, even after a lot of calculation, it never hurts to run something past a real wind tunnel test, or at least drive it down the runway like Burt Rutan.

My favorite Ames project was Vykukal's hard suit, capable of operating at close enough to 1 atmosphere to not require "prebreathing" preparations in a spacecraft with normal Earth atmosphere (ISS, Shuttle). I think NASA made a major mistake not pursuing this. We may yet regret not having the capacity to get into a spacesuit in a real hurry.
