The Twilight Zone Tower of Terror at Disney’s Hollywood Studios stands exactly 199 feet tall due to specific Federal Aviation Administration (FAA) regulations and Florida state law. Any structure reaching 200 feet or higher is legally required to be equipped with a flashing red aviation warning light at its peak to alert passing aircraft. Disney Imagineers felt that such a modern, pulsing light would completely shatter the carefully crafted "atmospheric magic" and period-appropriate illusion of a 1930s-era abandoned hotel. By capping the height at 199 feet, they successfully avoided the requirement while still maintaining the structure's status as one of the tallest attractions on the property. This same "under 200 feet" rule was applied to Expedition Everest in Disney’s Animal Kingdom, which stands at 199.5 feet for the exact same reason—to keep the mountain looking authentic without a blinking red light on its summit.
