Due the to the negligence of the US military exercises on the island of Okinawa, students have had to be evacuated 671 since the beginning of 2018. With past accidents recently where military aircraft parts (windows and such) have literally fallen from the sky onto school grounds, students have been on guard all year round. The US military constantly flies aircraft over civilian grounds, which include many schools and universities, ultimately endangering the lives of Okinawans.
