The "MK Ultra" was not the only dark experiments devised by the brutal ex-third Reich scientists. As the "MK Ultra", rolled on there was another offshoot known as "Operation Midnight Climax" which saw Paperclip scientists experimenting on people who had been lured to various CIA safe houses by prostitutes and then drugged in order to analyze the effects of LSD on the mind.
Many of the scientists brought to our country were die hard third Reich followers who could never change their political views. In all we ended up bring over 1,600 German scientists, spies, and engineers across the Atlantic specifically to work on Paperclip projects.
Eventually our country released hundreds of declassified documents which revealed the goals of Operation Paperclip and the experiments which were conducted by the previous German scientists here in America. Don't think for one moment that these previous German scientists were trusted by America for they were not. Every project they conducted was supervised by CIA officials with many intelligence agents monitoring all aspects of the program.
