The Chilean government declassified a video and report about a UFO sighting that occurred more than two years ago.
The video was picked up by a Navy helicopter at an altitude of 4,500 feet between the port of San Antonio and Quinteros on Nov. 11, 2014.

The chopper's infrared camera detected a UFO, which appeared to be flying at a similar speed to the helicopter, about 152 mph.
More info from the report (translated by Google):
The sighting was visually confirmed by the two officers who made up the crew (pilot and camera operator) and lasted more than 10 minutes.
Officers questioned Air Traffic Control whose radar failed to detect the object.
They also received no response from the unknown traffic when trying to interrogate it in the frequency arranged for these cases.
The DGAC's radar control system failed to capture the object but confirmed, in turn, the absence of authorized traffic in the vicinity of the helicopter.
On two occasions, the object seems to throw a trail of some element that could not be specified.
Some analysts have suggested the hypothesis that it is a medium-sized line aircraft and that the stelae of the detachable element may be the reserve water inside the apparatus, thrown by the crew. However, meteorology asserts that neither the altitude at which the object moved, nor the ambient temperature of that moment, allowed such a wake of condensation.
The object disappeared lost in the clouds.
The object remains unidentified. Check out the video for yourself below.
