Barra International Airport, Scotland
This is a unique airport in a sense that before taking off or during landing, the plane has to pass through the waters. When there are no landings, people actually stroll around the beach. At night, pilots only use the lights from passing cars in order to assist them during landing. Only those who are really knowledgeable in landing and taking off in this condition are allowed to fly planes that land in this airport. Despite this, it is still considered an international airport.
