During WW II, the US Air Force established a base on North Seymour, a part if the island of Baltra. Crews stationed at Baltra patrolled the Pacific for enemy submarines as well as providing protection for the Panama Canal. After the war the facilities were given to the government of Ecuador. Today the island continues as an official Ecuadorian military base. Until 1986, Baltra was the only airport serving the Galapagos. Now one of two airports, most flights operating in and out of Galapagos still fly into Baltra.
