There used to be a website or post where I originally saw this … I can’t find it any more. And there are no more easily accessible websites that can diagram maps with ‘great circles’ on a globe. This was ten years ago and it used to be easy to find this stuff … interesting to see that most of those sites are either now gone or don’t work any more.

But from what I remember, the line between Halifax and the west of Canada skirted the edge of Africa and the edge of Australia to make it across the globe without touching any land mass or island.
