The world's shortest commercially serviceable runway is at Juancho E.Yrausquin Airport on the island of Saba, Netherlands Antilles, in the Caribbean. The runway is just 396 meters (1,300 feet) in length; most aircraft carriers are only slightly longer than this. Courtesy Fentener Van Vlissingen
The world's highest airport sits at 14,219 feet above sea level. Surrounded by mountains, Qamdo Bangda Airport in Tibet operates a scheduled airline service but requires an extra-long runway (13,794 feet) to accommodate the extended stopping distance caused by the lack of atmospheric resistance at that altitude.
