    Did NOT see live shot, did watch replay. As I said earlier, great fun for me. In 1958 was instructor at US Army School on guidance system of REDSTONE missile (a son of German V-2) I guess. We used a “stable platform” dependent on a gyroscope. Ours was first US one to send a man into space, although not into orbit. But we did watch a live shot at WIND SANDS PROVING GROUND and it is thrilling. But I went from that back to the Univ and became an English Lit professor and later academic designer, finally a Greek Catholic priest to end my active career. But still fascinated how science has changed including missile technology.
    This has been a brilliant course for me, the content and the lecturer. Thanks

    Reminds me of the early launches in the 1960s
