Reminds me of a trick question from the time Finnair started to fly over the pole: Once there was so much demand, that they had to fly with two planes. They flew side by side, directly over the pole. So one of them crossed the international date line and the other did not. How come they landed on the same date?
- dmichulke 5y agoIf you fly over the pole you basically cover 180 degrees of longitude, and it matters little whether you take the 180 that cross the date line or the 180 degrees that don't. Crossing the date line is just an artifact of the singularity at the pole.
