Tens of thousands of people gathered for a rally in the Japanese City of Okinawa on Sunday to protest against the planned deployment of U.S. Ospreys in the prefecture in the face of a series of problems involving the tilt-rotor military aircraft. \"It cannot be considered normal to live under conditions in which an Osprey may fall from the sky at any moment,\" Masaharu Kina, chairman of the Okinawa prefectural assembly, told the protesters at a seaside park in Ginowan, which hosts the U.S. Marine Corps\' Futenma Air Station. Organizers said 101,000 people took part in the rally.
