From the X-Files: Incredible, Unbelievable, Swimming UFOs By Peter Ewer

     I do not believe that UFOs represent visitation of aliens from other planets. First, the West has more than enough aliens to deal with, trillions too many. Second, why would any creature with more than two neurons to rub together want to visit Earth anyway? Surely, there is no intelligent life on this planet, given human behaviour?

“An in-depth government report “prepared by and for the military” and obtained by a Nevada newsroom, details a 2004 incident involving an alleged “UFO” sighting recorded by the US military off California’s coast 14 years ago. Dubbed the “Tic Tac” incident, the unidentified flying object “rendezvouses” with a huge underwater object. So named for the white, fast-moving, mint-shaped object that was involved, the video’s release made waves last year when it was first revealed by the New York Times. Over the course of two weeks in 2004, a 13.7-meter-long (45-foot-long) Anomalous Aerial Vehicle (AAV) defined as “aerodynamic” with “no visible means to generate lift” was detected by US naval ships in short glimpses.

According to IFLScience, based on the recently leaked report, the undated document suggests there may have been something in the water as well. F-18 aircraft were called into the area after the USS Princeton wasn’t able to lock on to the AAV (Anomalous Ariel Vehicle.) The report details the moment a pilot noticed a disturbance under the surface of the water resembling a “barely submerged reef or island”. As the pilot flew away, the object reportedly disturbed the water underneath it in “frothy waves and foam” resembling water that was “boiling.” The unidentified flying “Tic Tac” object was potentially rendezvousing with the massive underwater one, according to the report.

     I do not have an explanation of all the details of this. But, whatever is going on, it is highly likely to be human caused. There is no reason why UFO aliens would be playing a game of hide and seek. Any alien worth their salt would already be lining up to reap all the benefits of the social welfare system, and since we do not see little green men at Centrelink, I assume that they don’t exist!
