A recently released U.S. diplomatic cable reveals that the Mexican Congress convened a hearing on September 12, 2023, at which experts testified about Unidentified Anomalous Phenomena (UAP) in connection with a proposed “Aerial Space Protection Law.” The document, a State Department political blotter covering events in Mexico from September 11 to 15, 2023, was made public through the Department of War’s PURSUE archive on May 8, 2026. According to the cable, designated “State Department UAP Cable 5, Mexico, September 16, 2003,” the testimony was a central part of a debate on the proposed legislation.
The document’s description states that, if approved, the law would “make Mexico the first country to formally acknowledge the presence of alien life on earth.” Experts who addressed lawmakers urged them to recognize UAP, guarantee airspace security, and permit scientific study of the phenomena.
The cable notes that the experts presented “alleged alien corpses and videos of Mexican pilot’s encounters with fast-moving flying objects during flight.” However, the document also records “disagreement about the efficacy and validity of the purported alien corpses.” The State Department record provides no further details on the nature of that disagreement or the specific content of the videos shown. The cable, classified as “UNCLASSIFIED” and released in full, was part of a routine weekly political roundup for the U.S. embassy in Mexico.
Its official summary offers limited detail on the UAP testimony, as the document’s primary purpose was to report on a range of political developments. The blotter also covered internal party disputes within the MORENA party and electoral commission appointments, with the UAP hearing listed as one of several notable events.
Background from non-government sources indicates that Mexico has a documented history of alleged UFO encounters. A Wikipedia entry on “UFO sightings in Mexico” describes the page as “a list of alleged sightings of unidentified flying objects or UFOs in Mexico.” This context is not directly referenced in the State Department cable and does not specifically address the 2023 congressional hearing or the proposed Aerial Space Protection Law. The State Department cable does not offer any U.S. government assessment of the validity of the claims made during the hearing.
It presents the information as a factual report of events in Mexico, without endorsing or refuting the testimony. The document’s tone is consistent with standard diplomatic reporting, focusing on political developments rather than scientific or technical analysis of UAP claims.
Several key questions remain unanswered. The document does not specify the outcome of the congressional hearing or whether the Aerial Space Protection Law was subsequently voted on or enacted. It provides no details about the identity or credentials of the experts who testified, nor does it describe the alleged alien corpses or the pilot videos in any substantive way.
The cable also does not indicate whether the U.S. government conducted any independent investigation into the claims made during the hearing. Future releases from the Department of War’s PURSUE archive may contain additional cables or reports from the U.S. embassy in Mexico regarding the status of the proposed law or any follow-up actions by the Mexican government.
For now, the official record confirms only that the Mexican Congress formally considered testimony on UAP and alien life in September 2023, with the outcome of that consideration remaining unclear.
