Okinawa Gov. Takeshi Onaga denounced the U.S. military as "crazy" Wednesday following the third mishap this month involving an Okinawa-based U.S. helicopter.

"The U.S. military is out of control. They can't exercise any oversight, there are no signs they will reform, and the Japanese government can't handle them," Onaga told reporters in Naha on Wednesday after an AH-1 attack helicopter based at U.S. Marine Corps Air Station Futenma made an emergency landing at Tonaki village Tuesday evening.

Onaga made the remarks in the morning just before traveling to Tokyo. There were no injuries to the crew or to local residents in the incident, which comes just days before a local election on Feb. 4 where Futenma's relocation will be a key issue.
