    Frank Reed you wrote: “In Hart's "Romance of Yachting" there's a peculiar table for range of visibility. See below (attached). How many problems can you find with this table?”

    Yes, there must be several problems.  I can see at least three after a quick look.  Therefore, as a bonus, who can ‘back engineer’ the table to calculate how Hart worked out his values (except in a dream)?  Lateral thinking hint:  Bomber Command Navigators didn’t change from using MPH to knots until 1st April 1945*.  Yes, really; why on Earth didn’t they wait at least until VE Day 8th May.  DaveP
