For the first three quarters of this video, this appears to be a blimp maneuvering in the sky behind the Statue of Liberty. Nothing unusual there. But then the thing speeds up, going much faster than a blimp, and emits a stream of smoke. This is very similar to a 1952 sighting described by Dr. Paul A. Hill in his book Unconventional Flying Objects. The only caveat here is that this poster has a number of UFO posts–but they’re certainly not CGI effects. Rather, they’re more-or-less wishful thinking, not actual UFOs. This, however, is a very different kettle of fish. This may well be a craft of unknown origin.
