↳ In-reply-to » Came across a twitter post claiming that there is a UFO in a building, meaning the ufo crashed, and then the building was built to cover it.

It’s the same type of antenna on both buildings, all though one is a actual building, and the other is just the antenna with a smaller building under the mesh structure.
I often fly flightsims, its my hobby, so I often work with waypoints, so I now just looked up the waypoint to find it’s information, to do that I looked up the closes airport, then looked around until I found the waypoint:

So would they really place a navaid on a building that contains a UFO? I do not think so.
Would a UFO crash that close to Seoul without a since photo or video? I do not think so either.
