UFO in New York: Is This a UFO Sighting in New York? – There seems to be a lot of buzz in UFOs. After the recent UFO sighting in China and inner Mongolia which prompted the halt of airline operations, a new UFO sighting, this time in New York, has been the talk of many speculators.

The UFO sighting buzz came from a lot of twitter chatters. A video has been posted in Youtube about this alleged UFO in New York caught in a day light with clear sky. Some said that it was just a set of balloons flying in the sky while others say that  it was just an optical illusion in the sky. Below is a picture shared in Twitter of the alleged UFO in New York:

However, based on some arguments thrown by those who saw the alleged UFO sighting in New York, they cannot be considered as balloons because they are not drifting or moving but they are hovering. Others said it lasted for over 45 minutes so definitely it cannot just be a set of balloons.
