This UFO sighting is very misleading considering the far away look the objects are showing. We can see white glowing spherical shapes hovering in the sky over Orly airport near Paris in France.
But when we take a closer look of some of the zoom in part of this video we can see clearly that theses are most probably commercial airplanes.
However we cannot be sure that they all are commercial airplane, especially the light completely on the left for which the viewer never zoom-in.
