The difference between a helicopter and UFO
In this video you can see daytime footage of helicopters filmed with the same camera am filming UFOs.
I have a SONY Cybershot DSC-HX300 with 50 optical zoom, and 100 digital zoom.
Filmed in night scene with lux on zero.
After the daytime footage there are three videos of this craft what you see on the picture above here.
That craft is one of the unknown crafts flying in my area, and what i found out is that this craft is flying around worldwide.
But thats another story.
Now i just wanted to point out the difference between helicopters i film in the evening and this craft.
And its normal that in the evening the sound should be more louder, but see for your self.
