Speaking of AEDC's 16T and 16S, I have spent many hours testing down there. Great wind tunnels, not much to do that was interesting around there for fun. And they always ran all night so we crashed at the motel during the day.

We would select a Mach number which was indeed the same Mach number as the full scale airplane and and let the tunnel guys work out what was needed. We always wanted the highest Re that they were willing to run the tunnel to. They shook the earth when running.
