    Modern Navigators Are Numb To The Universe
    From: Paul Hirose

    Recent article at the Avweb site:
    
    "When I was a callow lad, private pilot ground school was interactive.
    It was interactive not in the sense of the Pavlovian clicking of choices
    on a webpage, but of having a human instructor who actually talked and
    answered questions. Chalk was a thing then.
    
    "One of the instructors must have been an old school oceanic navigator
    because during the section on basic navigation, he produced and
    demonstrated a sextant of the sort used by World War II-era crews to
    find their way across the Pacific. I remember two things about this
    instrument. It had a bubble and my first attempt at reducing position
    with it put us in Indiana, 600 miles away from where in fact we were in
    North Carolina."

    I have never heard of the book he mentions.
    
    When I worked in B-52 maintenance in the early 80s, the little tubes in
    the terrain computer had been replaced by transistors on circuit cards.
    It was still an analog computer in the same case, now mostly empty space
    since the volume of circuitry had been reduced about eightfold.
