    Celestial lines of position were not the norm until well into the twentieth 
    century. But it would be interesting to compare the navigation at earlier 
    points in this expedition, before things became desperate. Did they use LOPs 
    at any point? Or was it latitude by meridian altitudes and longitude by time 
    sights even when they had the luxury of warm quarters and dry charts?
