Roswell 1947, crash of a space vehicle reportedly to have a surface skin that could not be burned, cut or otherwise damaged. How could you bring down such a craft? What force would it take to do so?Well, I know of only one person to come up with something that could do thatat that time period........Nikoli Tesla.Not only did he try to sell his death ray machine to the US, but also England. Both turned him down.The ray reportedly could knock down entire flights of bomber formations.His warehouse burned to the ground and all records were lost. I wonder..........Look up Tesla. That is who invented 60 cycle AC that runs your house, as well as a host of other inventions.
