What breaks the heart about this 25-year-old footage is the matter-of-factness of it: here's a boat, here are tourists, here are the Twin Towers, here's more of the New York skyline. Back then, the towers were just eight years old, and there was no reason to think they wouldn't be a part of the scenery forever. Vacationer footage unremarkable a little over five years ago now becomes a historical record.
