| The other good story is the C-130 navigation computer freaking out when flying into Bar Yehuda https://avgeekery.com/challenge-flying-sea-level/ |

| I wonder if there is a list someone of planes that have had glitches when crossing various borders or boundaries on the Earth? I remember hearing of a fighter a long time ago whose autopilot flipped out when it crossed the equator, due to sin(latitude) becoming negative. |

Maybe the system was just not tested to certification standards out there, or maybe it would do something really stupid and want to fly upside down or backwards! Either way, I wasn't going to be the pilot finding out on a dark night. | | |
