GINOWAN, Okinawa Prefecture--Children at an elementary school here on Feb. 6 could finally use their playground for physical education classes instead of preparations to avoid falling parts from U.S. military aircraft.

The Futenma No. 2 Elementary School in Ginowan, Okinawa Prefecture, had suspended the outdoor classes after a window weighing about 8 kilograms fell from a U.S. Marines’ CH-53E helicopter and landed on the playground on Dec. 13, 2017.

Since the accident, the school has held evacuation drills for students based on the scenario that a helicopter was approaching.

The school is located next to the U.S. Marine Corps Air Station Futenma.

According to the Ginowan city board of education, classes that have completed the evacuation drills can resume physical education activities on the school ground.

The Defense Ministry also plans to construct roofed evacuation shelters at the Futenma No. 2 Elementary School where children can shield themselves from falling aircraft parts.

After the window accident, U.S. forces said they will avoid flying over schools as much as possible.

However, the Futenma No. 2 Elementary School suspended the use of the playground, saying the safety of the children has yet to be guaranteed.
