White UFO near Eiffel Tower, Paris

On February 27, 2015, a live webcam located near the Eiffel Tower (in Paris, France) has filmed a white unidentified flying object. What is it?

Scott C. Waring explains:

This UFO was capture not in person, but seen on live Internet cam. I believe the cam above was the correct one, but not 100% on that. The woman (Anna Toth) who saw it recorded it with her camera, rather than a screen recorder, causing the wavily lines to appear on the youtube screen. I have watched her videos for a few months and can say that she only posts real or believed to be real objects. I to use the live cams from time to time to search for UFOs. The digital camera will often pick up the UFO where normally the human eye would not even notice its existence. Try it sometime, you might get a surprise like Anna did. SCW
