Theories about what happened to missing Malaysia Flight MH370 now span a 2 million-plus square mile area of open ocean and southeast Asian land, including one mysterious island in the Indian Ocean known as Diego Garcia.

While aviation experts and armchair theorists continue to come up with plausible locations, the jet could have landed or crashed. Many theories have included Diego Garcia as a notable landing strip.

The island atoll is a British territory in the central Indian Ocean and is home to a United States Navy support facility - not exactly a U.S. base, but a home for 1700 military personnel, 1,500 civilian contractors, and various Naval equipment.

The island - named after 16th century Spanish explorer Diego Garcia de Moguer - gained some notoriety in the past 10 years after reports claimed that the U.S. used Diego Garcia to transport and detain alleged terrorists.
