We all have heard stories of UFOs(Unidentified Flying Objects) which is known as alien spacecraft that is visiting around earth and post that many rumors start to build up but there are facts about UFOs too like in this video where a helicopter can be seen being engulfed by an unknown flying thing which is known as alien spacecraft and it is very amazing to see how fast this thing is completed.

After few seconds it seems that there was nothing in the sky, neither the helicopter nor the UFO. No matter how advanced our technology have become it is a proven fact that we are still lagging behind by a mile if we compare it with the powers of a different world.
