The Navy calls the Marine Corps Air Station in Funtenma, Okinawa, Japan “the most dangerous in the world.” Landing there requires passing over 16 schools, hospitals, and city offices. The more than 3,000 people living in what is supposed to be a “clear zone” is just another risk factor. Also, the city of Ginowan, with 96,000 people, surrounds the air station. In 2004, a helicopter crashed at Okinawa International University.
