The Atomic Bomb Tests of the 1950's included testing on U.S. Soldiers.
They were NOT permitted to talk about the experiment under threat of ten years in prison and a ten thousand dollar fine. Over fifty years later only a handful survive (Out of thousands).
I've also heard that there were secret missions to space and eventually to the moon and that some astronauts died. It seems that these events were not published. In some cases, perhaps, some UFOs came from government. Perhaps, some alleged aliens were deformed humans. Perhaps, in some cases, that some of the experiments, including atomic bomb testings, etc, deformed humans, animals, etc. Perhaps, some women were deformed. So, the feminists should learn about that and began protesting, etc.
