An eyewitness traveling on a train passing near Rome noticed three glowing lights in the sky that were in the shape of a triangle (you will watch the video below).
Some people suspect that it is a reflection of the light in the window. But if it was a reflection in the window, it would move independently of the ground and in relation to the back of the seat on the right side as the cameraman moved the camera.
Moving the camera would cause any reflection to move with it, as can be seen in the scratches on the window. However, the lights remain perfectly positioned above the ground below them.
Like the US Air Force TR-3B, triangular UFOs have been observed across Europe for decades.
