RIP Neil Armstrong. He was most definitely part of the "right stuff" which led up to leaving the confines of this planet and stepping foot on another celestial body. What I most admire of him. other than his unbelievable courage, not just by doing the mission, but in all of his endeavors up to that time, he pushed the boundaries and limits of every machine he ever piloted. Including both space missions he flew. He encountered unforeseen problems, solved them and made for successful missions. What I also admire about him is how he handled himself and what he did. The consummate professional, giving credit to and where all was due. He was an integral part of a greater cause. We have been blessed as a nation to have such a great man.
