The Kadena Municipal Assembly in Okinawa adopted a resolution and a statement of opinion Wednesday on a recent mishap involving a U.S. F-15 fighter jet at the U.S. Kadena Air Base.

The assembly demanded that the U.S. military unveil measures to prevent accidents and that they remove the F-15 squadron from Kadena.

In the May 2 accident, the left main gear of an F-15 collapsed when the jet made an emergency landing at the base. It managed to proceed down the runway, finally halting in a greenbelt area.

The resolution is addressed to the U.S. ambassador in Japan, the Kadena air base's 18th Wing commander and others, while the opinion statement is addressed to the prime minister and the head of the Defense Agency.

In the documents, the assembly states that F-15s account for more than half of fighter jets that have made emergency landings at the air base during the last fiscal year, and that the jets have been involved in a number of accidents.
