State Department UAP Cable 5, Mexico, September 16, 2003

On September 12, 2003, the Mexican Congress held a hearing on unidentified aerial phenomena as part of a debate over proposed language in an Aerial Space Protection Law. The hearing included testimony from experts, including Mexican journalist Jaime Maussan and former U.S. Navy pilot Ryan Graves, who had previously testified before the U.S. Congress. According to the file, the experts asked legislators to formally recognize UAP, guarantee airspace security, and allow UAP to be studied. If approved, the proposed law would make Mexico the first country to formally acknowledge the presence of alien life on Earth.

During the hearing, experts presented videos of encounters by Mexican military pilots with fast-moving flying objects during flight. The witnesses described these objects as aerial phenomena they could not identify using conventional explanations. Maussan also presented two alleged alien corpses as physical evidence. According to the file, Graves expressed concern that the presentation of the alleged remains undermined the credibility of the pilots' reported encounters, which he characterized as serious accounts by trained military personnel. Graves specifically lamented that Maussan's display was what he called an "unsubstantiated stunt" that distracted from the pilots' experiences.

The file notes that scientists had previously discredited other alleged alien corpses that Maussan had presented as evidence of alien life. This disagreement over the validity of the physical evidence presented to Congress reflects broader uncertainty about the nature and significance of the phenomena being discussed. The document provides no determination as to the origin or explanation for the aerial objects encountered by the pilots.
