Newly declassified FBI files released as part of the U.S. government’s ongoing PURSUE archive reveal a previously unseen letter from a Mexican inventor to a U.S. scientific commission, offering his theories on “stratospheric aerostats” — what he notes the public commonly calls “Flying saucers.” The document, titled “65_HS1-834228961_62-HQ-83894_Serial_220,” was released by the U.S. Department of War on May 8, 2026, and is part of a broader collection of records concerning Unidentified Flying Objects (UFOs) and flying discs documented between June 1947 and July 1968.
FBI Case File Reveals Inventor’s Letter and Broader UAP Investigation
According to the FBI’s official description of the case file, the records include “investigative records, eyewitness testimonies, and public reports” concerning UFOs and flying discs. The file encompasses “high-profile incident accounts, photographic evidence from sites like Oak Ridge, TN, and technical proposals regarding potential propulsion systems.” The FBI notes that while a partially redacted version of this file has been available on its public vault, the version released under PURSUE is “the complete case file with several newly declassified pages and only minor redactions.”
The document excerpt begins with a letter dated March 19, 1950, from a man identified as Michel Angel Garcia Macias, a “Pianist Composer Discoverer and Ideographic Inventor” residing in Veracruz, Veracruz, Mexico. The letter is addressed to “the President of the Commission of Scientific Investigation of the United States of North America” in New York. In the letter, Macias writes that he is sending his “STUDIES” to the commission because he believes it is his duty to make them available for “deep consideration.” He states that his work concerns “stratospheric aerostats (?) → or Flying saucers as people commonly call them,” and adds that he believes “your great Nation, making use of ATOMIC force, possesses” them.
Before outlining his idea, Macias provides a list of previous inventions he claims to have conceived as an “IDEOGRAPHIC Inventor,” which he states were “REGISTERED and PATENTED by other persons whom I do not know.” These include a “GOTE-GRADUNS” (Drop Graduation) device, which he says originated from studies on atmospheric graduations; “AUTOMATIC SHOVELS” for dump-trucks or concrete-mixers, which he says he designed after observing workers at a port; and a “ROOM FOR MEASURING OPTICS” for vision examination, which he says he has not registered. He also mentions a “GRADUAL CENTIMETRIC MUSIC OF THE FUTURE” related to sound composition, and a “FERROCYFACTOMETER and the FERROCEMACTOMETER” intended to eliminate railway and automobile collisions. The letter continues with descriptions of other unregistered inventions, including a system for “the distribution and division of TIME on CLOCKS of the whole World” and a method for “preventing the sinking of big Transatlantic liners.”
The document includes handwritten annotations on the translation. One note suggests that the writer intended to write “aereo-estaticos estratoesfericos” instead of the original phrasing. Another annotation explains that the writer “frequently uses capital letters when there is no apparent need for them,” which the translator retained. A third note clarifies that the term “Camiones de volteo” literally means “trucks for turning over or revolving.”
PURSUE Archive Context and What Remains Unanswered
Per a Wikipedia summary of the United States UFO files, the documents released under the PURSUE archive are part of a broader initiative that began on May 8, 2026, under the administration of Donald Trump. The Wikipedia entry describes the collection as “a collection of declassified United States government records concerning UFOs, also called unidentified anomalous phenomena (UAPs),” and notes that the releases were announced to continue as “repeated, ongoing, expanding releases of UFO materials.”
The letter from Macias raises several questions. The official description of the FBI case file does not specify any incident date or location associated with this particular document, nor does it indicate how the FBI obtained the letter or what, if any, investigative action was taken in response. The document does not provide evidence that Macias’s inventions were ever built or tested, nor does it clarify whether the “Commission of Scientific Investigation” he addressed ever responded. The letter itself does not contain any specific claims about UFO sightings, crashes, or recovered technology beyond the inventor’s assertion that the U.S. possesses flying saucers using atomic force.
As the PURSUE archive continues to release additional materials, readers should watch for further context on how the FBI processed and categorized letters from the public during the early Cold War period. The case file, which spans from 1947 to 1968, likely contains many other records that may shed light on the government’s systematic approach to UFO reports. For now, the letter from Michel Angel Garcia Macias stands as a curious artifact of a time when citizens felt compelled to share their ideas with the U.S. government about what they believed to be secret advanced technology.
