So, what I learned today (but also might have learned around 2010 maybe):

• is that Mackiernan and Bessac were not only "listening for Nukes going off and being tested with advanced Electronic surveillance at the time, they were also trying to aid Tibet in Fighting off the Chinese. However, Tanks and Planes defeated Tibet eventually through Khampa warriors being Straffed by planes and blown apart by Tank shells and machine guns. A rider with a good rifle is no match for planes and tanks.
•  
• However, Bessac was also an Anthropologist studying Tibetan and Chinese culture at that time too so likely he brought home a lot of knowledge about both Tibet and China to the U.S. and Europe then too. 
• Begin quote regarding the book "Into Tibet".
