The shortest commercial runway in the Caribbean—and the world—is at Juancho E. Yrausquin Airport on the island of Saba. The runway is a mere 1,312 feet (400 meters) long. It is flanked on one side by high hills and on both ends by steep cliffs that drop straight into the sea. Because of its extreme length and challenging approach, the airport is closed to jet traffic; only specific "Short Take-Off and Landing" (STOL) aircraft, like the De Havilland Canada DHC-6 Twin Otter, and helicopters are permitted to land there. Pilots must undergo special certification and training to navigate the intense crosswinds and the "aircraft carrier" feel of the landing strip. Despite its daunting appearance, the airport is the primary gateway for tourists visiting Saba and has a remarkable safety record. Passengers often describe the landing as a thrilling, once-in-a-lifetime experience that provides a stunning aerial view of the island's volcanic terrain before a sudden, sharp halt on the tiny strip of asphalt.
