Navigation problem
Here's a cute trivial problem I usually use to kill time with curious students.
There are places on the Earth where you can fly; 1 mile south, then 1 mile east (or west), and then 1 mile north, and end up in the same place. One of these places is the north pole. Where are the others? -- Regards, BobF.

There are an infinity of them, but I think the most distant one from the pole is the order of 1 plus1/6.28 miles from the south pole.
