The encounter known as the "Tic Tac" took place in November 2004, during training exercises off the coast of Southern California. It became public thirteen years later and changed how the U.S. government talks about unidentified objects. The case rests on a small number of named witnesses, a few sensor records and a great deal of subsequent argument. Here is what is on the record.
The setting
The USS Nimitz carrier strike group was conducting pre-deployment training in the Pacific. One of its ships, the guided-missile cruiser USS Princeton, carried an advanced radar system. According to accounts from crew members given later, the Princeton's radar operators had tracked unusual returns in the area over several days before November 14.
What the aviators reported
On November 14, 2004, two F/A-18F Super Hornets were directed toward one of these radar contacts. The best-known accounts come from two of the aviators:
- Commander David Fravor, who led the flight.
- Lieutenant Commander Alex Dietrich, who flew the second aircraft.
Both have described, in public interviews and in Fravor's case in sworn congressional testimony, seeing a disturbance on the surface of the ocean and a white, oblong object above it, with no visible wings, rotors or exhaust. Fravor has described the object as roughly the size of his own aircraft. He has said that as he descended toward it, the object rose, appeared to mirror his movements, and then accelerated away faster than anything he had seen.
Shortly afterward, according to these accounts, the radar picked up a contact at the flight's planned rendezvous point, many miles away.
The infrared recording
Later that day, another aircrew from the Nimitz flew with a targeting pod and recorded an object on its infrared sensor. That recording is known as FLIR1. It shows a small object that the sensor tracks for a short time before it moves out of the frame.
How the case became public
| Date | Event |
|---|---|
| November 2004 | Encounter takes place during training off Southern California |
| December 16, 2017 | The New York Times reports on a Pentagon program that studied UAP and publishes the FLIR1 footage alongside two other Navy recordings |
| 2019 | The Navy confirms the recordings show unidentified aerial phenomena |
| April 27, 2020 | The Defense Department formally releases the three Navy recordings to the public |
| July 26, 2023 | Fravor testifies before a House Oversight subcommittee hearing on UAP |
The other two recordings, known as "Gimbal" and "GoFast," come from different incidents off the East Coast in 2015. They are often discussed together with FLIR1, but they are separate cases.
What the record supports
Pulling the documented points together:
- A Navy training exercise took place, and aircraft were sent to investigate a radar contact.
- Named, experienced aviators reported seeing an object they could not identify, and have repeated their accounts consistently and publicly.
- An infrared recording exists from the same day.
- The Navy and the Defense Department have acknowledged the recording as showing unidentified aerial phenomena.
What remains contested
Whether the visual sighting and the infrared recording show the same object. The FLIR1 recording was made later in the day by a different crew. It may or may not show what Fravor and Dietrich saw.
What the infrared recording shows. Some independent analysts argue that FLIR1 is consistent with a distant aircraft seen by a sensor at the edge of its resolution, with apparent motion caused by the sensor's own tracking. Others argue it is not consistent with any known aircraft. The recording alone does not settle it.
The radar data. Accounts describe radar tracks with extraordinary movements, but the underlying radar data has not been published. Without it, the most dramatic parts of the case rest on testimony.
The absence of an official identification. To our knowledge, no public government document has identified the object. AARO and earlier offices have not published a resolution of this case.
Why the witnesses matter
It would be easy to frame this as "pilots versus skeptics." That misses the point. The aviators are trained observers who reported what they saw and have not exaggerated it into claims about origin. Fravor has said he does not know what it was. The skeptical analyses focus on the recording, not on the honesty of anyone involved. Both can be taken seriously at once.
What remains unexplained
The object the aviators described. The visual account from multiple trained observers, paired with radar reports, has not been matched to any known aircraft, balloon, drone or natural effect in the public record. Until the underlying sensor data is released or the case is formally resolved, the Tic Tac remains one of the strongest unexplained cases on file, and one of the clearest examples of why the government began asking for better data.
