Object seen on a picture of an open sky, but it wasn't there when I took the picture.I was taking a picture of the sky because it was really clear and beautiful and there was nothing on it. But when I saw the picture, I saw something in the sky that wasn't there when I took the picture. So, I stare at the sky and there was nothing on it except beautiful and shining clouds. And in the picture you can see an unidentified flying object with a strange shadow that nobody saw, except on the picture. This picture was taken in Rionegro, Antioquia, in Colombia and the object was flying upon the Rionegro airport but is clear not an airplane.
