Traditional skyscrapers owed their stability to a system of large vertical columns running through each floor at intervals of feet, with the exterior walls providing little support on their own.
The builders of the World Trade Center put extensive research into the effect of wind on the towers, commissioning one of the earliest wind tunnel studies for a skyscraper and performing perceptual tests disguised as eye exams on unsuspecting subjects to figure how much the building could sway in high winds without people noticing.
