Scanning the sky earlier this month, Yumi Kuniyoshi, 52, notes it's a rare quiet day: no U.S. military aircraft are flying over her house in Urasoe, a small Okinawa city next to Ginowan, home of U.S. Marine Corps Air Station Futenma.

Even with all the windows shut, the noise of a jet overhead drowns out all conversation and the TV. It's not unknown for military aircraft to streak by at 3 or 4 in the morning, she said.
