BBC journalist David Lee reports on the ongoing efforts of South Korean groups to send news, money, and aid to North Koreans using high altitude balloons. It seems that South Korean authorities are making an effort to curb the balloon launches. It seems that the balloons still lack basic safety devices such as parachutes to slow the payloads down on landing. It also seems like the payloads are released by simple electronic timer mechanisms. You can only imagine that these flights are not done with any approval from local civil aviation authorities.
