Turns out that most (all?) of us have been wrong. At the end of Star Wars, the Rebel fighters fly down the length of a trench on the Death Star to deliver a warhead to an exhaust port. And for the past nearly 40 years, just about everybody has believed that the trench they flew down was the equatorial trench. But it turns out that it was a smaller longitudinal (north-south) trench. And it turns out that this is an obvious fact, once pointed out.
