If that was your explanation and if we go by your view that those were aeroplanes , this thread would already have moved into the Hoax box
These videos have been posted here many many times and are planes
who decides its the plane or UFO ?
UPDATE: Marcos González, of Agrupación Canopus, Chile, confirms that “sure, the night flight of the Air Force planes are a phenomenon that repeats itself every year around this time of the year and has been in many occasions recorded by the surprised spectators”.
