It is amazing how many antigravity projects (NASA, Airforce, Navy, Army, foreign nations, privately funded etc.) have been conducted without success. Unfortunately no documents have been made available as to the theoretical approaches, proposed and conducted experiments, and outcomes if any, until Project Greenglow.
The BAE Systems-funded Project Greenglow is well documented by Ronald Evans in his 2015 book Greenglow & the search for gravity control. As was typical of the scientific community its announcement was not well received. One American physicist said at that time, "One can only conclude that at the higher levels of these organizations there are people who don't have a very sound grounding in fundamental physics." I must say, these physicists were not very adventurous, and worse, didn't want others to attempt something that might overturn their worlds. Did the universal failure of all these antigravity projects point to the need to overturn legacy physics?
