Narrative:
The US Central Intelligence Agency (CIA) acquired seven Neptunes in 1954 and configured them with cameras and electronics intelligence gear. Five of those were stationed in Taiwan and operated by the Republic of China Air Force.
They were reportedly used to conduct intrusion ELINT missions over mainland China, dropping and supplying agents, and dropping propaganda leaflets. Missions were usually flown at night.
The Neptune crashed into a hill near Kunsan, South Korea, during a low level ferry flight from Hsinchu, Taiwan to staging area in Kunsan, South Korea.
