Unknown Date, Daytime
In my opinion, this is also a very good UFO video. The UFO is small and seems to be oval-shaped. The object, which is very close to the camera, flies towards the building then it turns and flies to the left. The UFO can be seen 41 seconds into the video. Furthermore, a second video showing this incident was found on YouTube, which corroborates the first.
The National Geographic documentary was about the legend of Atlantis.
