Original Note:
The straight line is defined in the homeomorphic space to the sphere manifold that is the Earth. Not all straight lines have to be defined in the 3D euclidean space we are used to. A sailor would perceive that they are going in a straight line (no turns) during all the way. https://en.m.wikipedia.org/wiki/Manifold
