At 23:02 UTC on 31 March 2023, a flight of U.S. F-16CM aircraft reported several bright objects moving west to east during a patrol associated with northeastern Syria. The crew estimated that there may have been ten to twenty objects. Contacts appeared in the targeting pod’s television mode for about twenty seconds before becoming dim and disappearing from the view.
The released six-page mission report records a brief comparison with a star and a claim of high altitude. It does not supply a complete image sequence, angular measurements, distances or an astronomical reconstruction. The account is a documented report of an unusual visual impression, rather than a demonstrated identification of the objects.
A sortie spanning two calendar days
The flight consisted of two F-16CM aircraft operating in support of Operation Inherent Resolve. The dated timeline begins with departure from Prince Sultan Air Base at 19:01 UTC on 31 March. It then records entry into Iraqi airspace at 20:07 and Syrian airspace at 20:58, when the flight checked on station.
The UAP contact field gives 31 March 2023 at 23:02:05 UTC. The flight left station at midnight and landed back at its Saudi base at 01:48 UTC on 1 April. This distinction prevents the following day’s landing, or a later document date, from replacing the actual observation date.
The release catalogue calls the file Mission Report, Iraq, 2023. For the case location, the mission’s own timeline and disclosed observer-grid area are more useful than that broad label. The observation occurred after the recorded entry into Syrian airspace. The departure base and the tasking country identify the operation, not a sighting in Saudi Arabia or the United States.
Bright contacts that became dim
The detailed UAP entry describes several bright objects appearing to move quickly from west to east, northeast of a location abbreviated RLZ. Its object-count field gives a possible range of ten to twenty. That is the crew’s estimate, not a verified catalogue of separately tracked vehicles.
The operators reportedly acquired possible UAP in the targeting pod’s television mode for approximately twenty seconds before an object became dim and disappeared from the view. The record does not specify that twenty seconds was the duration of the whole event. It is the reported interval for the contacts described in the sentence.
The report says no formations were seen during this observation, unlike unspecified earlier sorties. It does not identify those earlier sorties or provide their dates and records. They are not counted here as additional cases, and their brief mention is not treated as independent corroboration.
The account includes no detailed physical outline, measured dimensions or visible means of propulsion. The approved Multiple lights feature records the report of several bright contacts. It does not classify the contacts as spheres, triangles or an organised formation.
The altitude claim and the star comparison
The UAP field lists an altitude above flight level 600, while the observing aircraft was recorded at flight level 265. The public copy does not show how the higher altitude was established. It provides no target distance, triangulation or independent measurement that would allow UKPX to verify a height above 60,000 feet.
The description of rapid motion is similarly qualitative. The source gives the observing aircraft’s speed, but not a measured velocity for the contacts. An object’s motion across a view cannot, on its own, supply its true speed without distance and viewing geometry.
An analyst comment says the flight compared a possible UAP and a star through the targeting pod and obtained different results. That is a useful recorded check, but its method, settings and underlying images are not supplied. It cannot by itself rule out every astronomical source, satellite reflection or other conventional explanation. No particular alternative is claimed as an identification here.
What the report leaves unresolved
The source records no effects on people. Its UAP signatures field says no, and several other fields are blank. The released material does not include an independent radar track for the contacts or a completed investigation identifying them. Blank fields remain gaps, rather than proof for or against a particular object type.
The report also withholds the first-seen target location and portions of the observing aircraft’s grid reference. Those omissions limit a reconstruction of line of sight and viewing geometry. UKPX does not fill them with the aircraft’s launch base, a guessed target position or reconstructed redacted digits.
Assessment: Insufficient Evidence
UKPX classifies the case as Insufficient Evidence. The flight’s report is specific enough to preserve its chronology and description, but the publicly released material does not establish what the contacts were or verify their claimed high altitude and movement. The short star comparison does not close that gap.
The classification does not assert that the crew invented the observation. It reflects the difference between recording an account and establishing the physical nature of a contact. No extraordinary performance, non-human origin or particular conventional identification is presented as proven.
A broad observer-area pin
The report’s disclosed observer-grid prefix is 37SGA. The map uses the centre of that 100-kilometre Military Grid Reference System square, approximately 36.56° north, 41.79° east, as a broad reference in northeastern Syria. The conversion represents the grid square at the resolution actually retained for this map; it does not recover the removed coordinate digits.
This is an observer-area reference, not the contacts’ measured positions, a flight track or a visitor destination. The targets’ first-seen location is masked in the file. The Syria association is based on the actual mission timeline and observer area rather than the catalogue’s Iraq label or the Saudi departure base.

Page 1 supplies the airspace chronology, page 5 the dated mission timings and page 6 the observation, partial observer grid and analyst comment. Declassification in 2025 and the later release concern the record’s handling; the incident year remains 2023.
