Thanks for the thoughtful reply. I too have/had questions in regards to the curvature of the earth. Someone explained that, just like HAM radio, th e HAARP system could bounce it's rays off the stratosphere, kind of like shooting a bank shot in the game of billiards. Billions of dollars was invested into the HAARP program, with hundreds of millions in infrastructure. If there were military applications for HAARP I'm sure it would still be in use, just not "officially." Thanks!
