This reminds me of a backwoods hike I took with a friend some years back. We each brought a compass, "for redundancy", but it wasn't until we were well underway that we noticed our respective compasses frequently disagreed. We often wished we had a third to break the tie!

- jwr 3y agoMy grandfather was working with Stanisław Skarżyński, who was preparing for his first crossing of the Atlantic in a lightweight airplane (RWD-5bis, 450kg empty weight) in 1933. They initially mounted two compasses in the cockpit, but Skarżyński taped one of them over so that it wasn't visible, saying wisely that if one fails, he will have no idea which one is correct.

- jefftk 3y ago> if one fails, he will have no idea which one is correct Depends how it fails! For example, say, when you change direction one turns and the other doesn't.
