    Titanic vs Endurance
    From: David C
    Date: 2022 Mar 11, 13:29 -0800

    The finding of the Endurance has raised several issues in my head. I will  list them here.

    The news report stated that Endurance was found 5nm from Worsley's position. I googled "Titanic sos position" and  found a claim that the position was 13nm in error due to a minute (time) error in reading a deck watch. I do not know if this is correct. Worsley had a year on the ice to determine his position.  The Titanic navigators had much less time on a sinking ship.

    Worsley used lunar occulations of stars to determine time. Would typical marine navigators of the time know anything about such things? It is something that a land surveyor would have learned. I note that there was a physicist on board the Endurance.  Did the ship have a good library of surveying/astronomical/navigation books that they could spend a year studying? Should the physicist share some of Worsley's kudos

    Is a lunar occulation of a star a special case of a lunar i.e.  lunar distance=0?
