Yonhap News Agency :
While the rocket seems to have successfully separated its first and second stage boosters with debris falling in somewhat designated areas, the launch is still considered a failure by Seoul, according to Yonhap.
According to the agency the rocket “burned up” southwest of Jeju, the largest island off the south coast of the Korean Peninsula.
The missile “disappeared from radar” during the fairing separation stage, the agency added.
