    Re: Death to the Intercept Method!

     Frank,

    I just read Bob's message and now understand why the Sumner LOP method did not catch on very quickly.  Even now, when almost all navigators understand the concept of a LOP the time sight is thought of as Longitude and needing a noon sight for Latitude.  The idea that two time sights with slightly different latitudes will produce a LOP as good as the StHilary intercept LOP seems hard to grasp.

    We are a consertive group.

    John H.
