Back in 2014, the Chilean government CEFAA, an agency that does investigations on UFO related events made quite the report. They came in contact with what they call an unexplainable visual anomaly.
The anomaly was not showing up on the helicopter’s radar, but was definitely there. It did not show up on ground radar stations or any other stations for that matter. It was not an aircraft and the incident was made classified. This unidentifiable aerial phenomenon was quite the sight according to Alberto Vergara lead analyst from the Chilean Air Force photogrammetric department.
Now that this information is no longer classified we are able to watch the video recording from this incident. If you look closely the object is seen twice ejecting some sort of fluid. This UFO was traveling horizontally at the rate of a helicopter and is clearly not space debris. Look closely when it gets to 8:13 for the fluid.
