Black Triangle Sighting in Coimbra, Coimbra on 2017-09-14 14:39:00 – Triangular object is cloaked in clouds

I was watching the clouds as i searched for airplanes and did my usual report of the chemtrails in my area, noticed a strange cloud and zoomed in with the mobile phone to try to see better but due to the bright sunlight could not see the screen and only after reviewing the images on the computer did i notice that i had in fact filmed something similar to other secret projects like the tr3b or sr91 aurora or similar. i send the original video, the link of my youtube page as well as copies in slow motion and some photos with filter applied. i'm not sure but i was left with the feeling that there are more objects next to the triangular object. you will have to analyze better.Good news and your answer.Carlos vieira.
