This seems very similar to the Utah case, and other zip-by UFOs. The object looks like it's flying in from a long distance away, like the other side of the river.
I think, like with Utah, that it's actually pretty close.
Unfortunately, it does not seem to be a live shot.
Article: A rep for "Good Day New York," which originally aired the clip, said they couldn't say when the footage was recorded — but that it was likely within the last calendar year.
Some wild speculation in the NYPost article:
Article: If the supposed object did originate in the sky in the vicinity of Hoboken and then proceeded to travel all the way down river, passing the tip of Manhattan, it would indicate an incredible speed.
If the object traversed the 3-mile distance in four seconds, it would put its speed somewhere in the vicinity of 2,700 miles per hour — more than double the speed of an F18.
Article: "This is most likely an optical artifact from the helicopter glass in front of the camera, namely a bright spot from the reflection of sunlight as the camera gradually changes its orientation relative to the sun and the ground," Loeb tells The Post. "But even if it was a real object, the apparent speed is of an order the speed of sound and not extraordinary," Loeb concludes.
Article: Tim Gallaudet, a retired rear admiral in the United States Navy and CEO of Ocean STL consulting, agreed.
"For several reasons, looks like an artifact and not an actual UAP," Gallaudet told The Post, using the acronym for "unidentified aerial phenomenon."
