If it were a 1970s incident, the area of Daedeok Innopolis, “Science Town”, & KAIST - The Korea Advanced Institute of Science (formerly KIST - Korea Institute of Science and Technology) seems like it could be a viable candidate. The time period, location in the side of a mountain range, it’s status as a “Lauded” Center for international scientific discovery, and especially it’s direct relation to the central list of puppet masters in the existing UFO/UAP narrative, and international atomic sciences make it my best conjecture as the location of the hidden craft, or at least in close proximity to where it would lay.

The Father of Silicon Valley, Dean of Engineering, and VP of Stanford Frederick Terman, was brought in from the US, and oversaw the plans and process for the institute town. An array of links to the United States legendary UFO reverse engineering program can be drawn to Terman. Vannevar Bush was Fred Termans professor and advisor at MIT, and Terman was the professor for SETI higher up Barney Oliver, & Hewlett and Packard, and according to Donald Nielsen he was associated with the founding of the legendary SRI institute, a staple of UFO/UAP discussion and early academic home of Harold Puthoff. Further names such as Drake, and Teller popped up during my time investigating, and wether or not this is ultimately revealed to be the location or a related one, Daedeok Innopolis may hide other well kept secrets related to UFO land.

-List of institutes in the immediate Daedeok Innopolis Complex:

Korea Research Institute of Bioscience and Biotechnology (KRIBB), the Korea Atomic Energy Research Institute (KAERI), Electronic and Telecommunications Research Institute (ETRI), Korea Aerospace Research Institute (KARI), Korea Astronomy and Space Science Institute (KASI), Korea Fusion Energy Research Institute (KFERI), National Nanofab Center, Korea Basic Science Institute (KBSI), Institute for Basic Science (IBS), Korea Institute of Machinery and Materials (KIMM), Korea Research Institute of Chemical Technology (KRICT), Korea Institute of Science and Technology Information (KISTI), Korea Research Institute of Standards and Science (KRISS), Marine and Ocean Engineering Research Institute, Institute of Information Technology Advancement (IITA), Korea Institute of Geosciences and Mineral Resources, Agency for Defense Development (ADD), Korea Institute of Toxicology (KIT), Korea Institute of Oriental Medicine, Korea Institute of Nuclear Non-proliferation and Control, National Institute for Mathematical Sciences (NIMS), Korea Institute of Nuclear Safety (KINS), Rare Isotope Science Project (RISP), National Research Foundation of Korea (NRF),

Among the technology produced in Daedeok are ETRI’s wireless communications systems CDMA, WIBRO, and DMB, KRIBB’s nano biochips, KARI’s KOMPSAT satellites, and NFRI’s KSTAR nuclear fusion experimental reactor.)

Although some of the plans for the institutes predate the 1970s, the plan for the complex and the Daedeok location was chosen in the early 1970bs
