Recorded in January 2013 somewhere over Mexico. As he writes the author of the video, he originally thought he was filming a flight of a flock of seagulls in the sky. The objects are very similar in shape to birds. But then the man with horror I realized that these objects do not wave their wings like birds, in general never waved. At the same time, their movements are harmonious and synchronous.
