maptitude1: This map shows the longest straight line one can travel on land without crossing any major bodies of water. But this is actually a curved line, of course. If you wanted to walk along the earth in a straight line you would walk along the curve of one of the thin light blue grid lines in the ocean on the map because they are representing how the curve of the earth has been flattened into a flat projection. If the red line was actually straight in relation to this map, it would be curved in the same way as the grid lines. This means that it might not be a straight line through dry land only anymore because you might be passing through the Caspian sea in order to get through the little pass between Egypt and the Arabian peninsula. I could be wrong about that though. Map projections are tricky.This is roughly the same line drawn onto a map with a horizontally straight grid: -- source link
