Algorithms

The Gorse Fox has spent the day on the spreadsheets working on yesterday's challenge. Finding the official calculations was moderately easy, but getting them to work has been a nightmare. An ongoing nightmare. The Gorse Fox selected two point which were 6km apart... used the algorithm and it told him they were 15 nautical miles apart. Wrong! This is going to take further analysis. It's clear that the Gorse Fox's recollection of trigonometry and the use of radians in mapping distances on the surface of a sphere is a bit rusty.

Mid-afternoon, Urban-Cub arrived with Ellie. As Urban-Cub returns to work in the morning, we said we would take care of Ellie overnight and through tomorrow. Urban-Cub will come an collect her when she finishes.
