    I don't know enough to tell what Loran receiver is depicted. The face of
    the unit is never shown, just the green trace on the CRT. It looks like
    one of the APN-9 display diagrams in my book -- the one you use to make
    the initial coarse delay reading -- except that the 1000 usec and 5000
    usec pips extend above and below the baseline instead of only above. The
    1000 usec pips are dim and hard to see in the movie. In fact, on the
    first viewing I never noticed them, even when pausing the picture.
    
    On the companion disc is a feature on airline flying the 1950s. Some of
    the old pilots of that era are interviewed, and have a few remarks about
    the navigators they flew with:
    
    "The navigators seemed to be the ones who were best on algebra and were
    interested in astronomy and that sort of thing. Maybe they were a little
    smarter in some respects than the pilots."
    
    "They were considered the more educated and refined member of the crew."
