Black U-shaped UFO over Coimbra, Portugal

On March 5, 2018, a black U-shaped UFO was seen over Coimbra, in Portugal. This case was published on MUFON website.

The ufologist Scott C. Waring claims:

This U-shaped UFO is beyond rare! Often disks or spheres are seen, but this rare UFO popped up over Portugal this week. Lucky for us, a person was recording the sky and accidentally caught the UFO as it was slowly passing by.

Eyewitness states:

During the video recording for time lapse I noticed that something crossed the sky coming from south to north-it has a U shape. I cut part of the video for submission.
