As i was filming some planes that day, nothing really seemed unusual. i was in "Trier - Germany" on the parking of a supermarket.but as i was watching the material at home , in one video , i was surprised seeing 4 or 5 white dots crossing the screen.my first impression was that my camera caused those dots, but as i watched the about 40minutes footage , hey never appeared again.after watching the video several times, i seems to me , that those "Dots" where in the sky , fyling. so they dont seem to be reflections , because 1. i never had them in my videos ever before. 2. the sun was in the other direction. 3. one object seems to dissapear in the cloud , and in the next frame it reappears behind the cloud.i cannot say that those are aircrafts , because they must have been faster than any aircraft i would know. the only aircrafts which im concerned of , would be some like the black bird. but the black bird is black , and i would have heard it. i have one frame , showing a clear picture of a disc shaped metallic looking object which i isolated in my videos.i was pretty surprised when i watched the footage.here are the videos:*(Three links moved to Additional Evidence Section--CMS/sg).i hope to get your interpretations of them.thank youwith friendly greetings.
