On November 14, 2004, fighter pilot Commander David Fravor of the USS Nimitz Carrier Strike Group investigated radar indications of a possible target off the coast of southern California. Fravor said the operator had told him that the USS Princeton (CG-59), part of the strike group, had been tracking unusual aircraft for two weeks prior to the incident. The aircraft would appear at 80,000 feet before descending rapidly toward the sea, and stopping at 20,000 feet and hovering Fravor reported that he saw an object, white and oval, hovering above an ocean disturbance. He estimated that the object was about forty feet long. Fravor and another pilot, Alex Dietrich, said in an interview that a total of four people (two pilots and two weapons systems officers in the backseats of the two airplanes) witnessed the object for about 5 minutes. When Fravor spiraled down to get closer to the object, the object ascended, mirroring the trajectory of his airplane, until the object disappeared. A second wave of fighters, including pilot Lieutenant Commander Chad Underwood, took off from Nimitz to investigate. Unlike Fravor, Underwood's fighter was equipped with an advanced infrared camera (FLIR).Underwood recorded the FLIR video, and coined the description "Tic Tac" to describe the infrared image, but did not himself see any unusual object.  During 2014–2015, fighter pilots associated with the USS Theodore Roosevelt carrier strike group were operating off the East Coast when they recorded the GIMBAL and GOFAST videos while reporting instrument detections of unknown aerial objects which the pilots were unable to identify.  Source: https://en.wikipedia.org/wiki/Pentagon_UFO_videos
