During a 2014 patrol of the Chilean coast, cameras aboard a Chilean Navy (Airbus Cougar AS-532) helicopter picked up some unusual footage: a forward moving, unknown object, flying at a speed similar to that of the helicopter. The object was visible for 10 minutes and was seen by both the pilot and camera operator. The footage of the incident was recently declassified by the Chilean government.
The incident took place on November 11, 2014 during what was supposed to be a routine patrol between the Chilean ports of San Antonio and Quinteros. The Costa Rica Star reports that "the aircraft was flying at an altitude of approximately 4,500 feet on a clear afternoon with unlimited horizontal visibility, and the air temperature at that height was 50 degrees F (10 C). There was a cloud base above at 10,000 feet, and a layer of stratus cumulus clouds below. The helicopter was flying at about 132 knots, or 152 mph". Air Traffic Control reported that the object did not show up on their radar, and the DGAC confirmed that there were no other authorized aircraft in the area at the time. This rules out the object being a weather balloon or other small craft.
The officer manning the camera was filming the landscape when he noticed the object flying out over the ocean. The crew estimated that the object was traveling west-north-west at a distance of about 40-50 miles from the helicopter. The cameraman zoomed in on the object using infra-red for a sharper image. The result is what looks to be UFO footage filmed from the vessel. This is what he filmed:
The incident was the focus of a two-year investigation. During that time, research was conducted to determine if there were any instances of falling debris, satellites, or other similar objects. There were no such objects in the area at the time. Experts who viewed the footage -- astrophysicists, video experts, and engineers -- were unable to identify or explain the object. IPACO,a group from France that analyzes reported UFO footage, has expressed that they feel the object "was most probably a medium-haul twin jet airliner in a landing phase, flying ahead of the helicopter at a higher velocity, with a low altitude and a low velocity, in view of landing." The IPACO report is a compelling explanation, but the actual identity of the object remains a source of speculation.
