NVIS on 10,11 and 12 meter's??? Dipole

Ok maybe I am just out of date but as a kid I grew up with the military using NVIS Dad was career Army and Infrantry. I was taught that NVIS was best for 1-8Mhz and was for bridging the gap between ground propagation and sky skywave propagation. I was always taught that as you went up in Freq. it became less and less viable. I even read research from about 1920-1940's where they used 10K+ watts and tested in various soil types and the ocean.

So the other day I was laughing at some youtube...
