Anomalous aerial vehicle According to the document, it registered high speeds and became invisible at times.

Anomalous aerial vehicle U̳F̳O̳ investigators I-Team claim to have gained access to a copy of a P̳e̳n̳t̳a̳g̳o̳n̳ report describing an encounter between the US Navy aircraft carrier Nimitz and an unknown flying object, US media report.
The 13-meter-long, white object, nicknamed \’tic tac\’ for its resemblance to the famous candy, was seen off the coast of California for several days in November 2004.
Just a few months ago, in December 2017, a video was released in which a Nimitz fighter allegedly films the \’tick tock\’, which caused a furor in the US media. Now there is a report detailing what happened.
According to the document, the aircraft carrier Nimitz and the accompanying group of ships had several encounters with an anomalous aerial vehicle and tried to record its movements with the most sophisticated sensor systems in the world, capable of tracking a golf ball a hundred miles.
The main conclusions of the report show that the \’tic tac\’ was an object that did not belong to the US or to any other nation in the world. The latest US Navy technical equipment was ineffective at detecting it.
The “anomalous aerial vehicle” recorded very high speeds and even became invisible to both radar and the human eye. That is, an untraceable object, perhaps invincible.
In addition, the officers who took part in the operation reported a large object right on the bottom of the ocean, round in shape and about 90 meters wide. It appears as if the \’Tic Tac\’ has arrived to meet an underwater object.
The report includes statements from seven F-18 fighter pilots, as well as several radar operators on ships. Despite the seriousness of the encounter, the pilots were ridiculed once they related what happened. The initial report on the \’tic tac\’ case was not taken seriously.
The current document was drafted in 2009 and nowhere does it appear that it was the work of the P̳e̳n̳t̳a̳g̳o̳n̳. However, from I-Team it is affirmed that several sources of the organization assure that it is an authentic report and that it is part of a P̳e̳n̳t̳a̳g̳o̳n̳ program.
