GOFAST

Unidentified · motion explained

In January 2015, off Florida, an F/A-18F display seems to show an object racing over the sea. The display's own numbers place it at about 13,000 feet, moving roughly with the wind.

02 Parallax lab

The display shows what the camera sees, not where the object is. A slow, high object seen from a fast jet seems to sweep across the ocean behind it at great speed.

03 Images from the file

Only images from the records themselves: official pages, charts and photos, and drawings the witnesses handed in. Artist's recreations and AI-generated images are not shown, even when the catalogue includes them.

GOFAST infrared frame with AARO's yellow labels: sensor azimuth and elevation angles, range to target (4.0 nautical miles), 14° bank angle, Mach 0.61, altitude 25,000 feet and time 4239.
Official recordOne of the two frames AARO measured, with the data it read off the screen: the sensor angles, the range, the aircraft's speed and altitude. From them it worked out where the object was: at about 13,000 feet, well above the sea. [1 · p. 6]
AARO diagram: two cases side by side. At the top, the aircraft moves between t1 and t2; in the middle, the object at 3,962 m barely moves (265 m and 426 m); at the bottom, in red, the much longer “apparent distance travelled” over the sea.
Official recordWhy it looked so fast: the aircraft covers more than 2 km in 13 seconds and the object a few hundred meters. Projected onto the sea, the line of sight sweeps a huge distance: that is parallax. With the aircraft flying into the wind, the effect is amplified (right). [1 · p. 26]

04 Timeline

  1. An F/A-18F records with its infrared pod an object that seems to skim the ocean at high speed. [1 · p. 1]

  2. The video circulates after an unauthorized leak. [6][8 · p. 11]

  3. The DoD authorizes its release; the Navy hosts it in its FOIA library. [6][7]

  4. NASA analyzes the display's numbers: the object is at about 13,000 feet, moving at about 40 mph, a typical wind speed at that altitude. [2 · p. 28]

  5. AARO presents its analysis to the Senate: about 13,000 feet and 45 mph. [3 · p. 5][4 · p. 15]

  6. AARO publishes the resolution with every calculation: high confidence of no anomalous performance; the object is not identified. [1 · p. 1–26]

05 Hypotheses

Status as stated by the official sources cited. The archive takes no side.

06 Testimony

“the object is not actually close to the water but is rather closer to 13,000 feet.”
Jon Kosloski, AARO director · Senate hearing, 2024 [4 · p. 15]

07 Editor's reading

The editor's opinion, not an official finding. It rests on the records cited and changes if they do.

  1. Conventional explanation likely
  2. Open
  3. Anomalous
  • At about 13,000 feet, the speed that impresses in the video is parallax: the object moves at about 40–45 mph, roughly with the wind. [1 · p. 1, 3–4][2 · p. 28]
  • It measures one meter or less and never moves against the wind: it fits something drifting, like a balloon. [1 · p. 1, 4]
  • It is colder than the ocean and shows no propulsion heat. [2 · p. 28]
  • What keeps it open: no source identifies it. Unidentified does not mean anomalous. [1 · p. 1]
