I vaguely remember someone from the USAF coming forward in the 1990's and disclosing that the USAF had been planting UFO stories to provide cover for experimental aircraft development. Here is a NYT article from 1997 on the the CIA coverup. https://web.archive.org/web/20230726002122/https://www.nytimes.com/1997/08/03/us/cia-admits-government-lied-about-ufo-sightings.html https://web.archive.org/web/20230726002122/https://www.nytim... But I also seem to remember an airforce person coming forward with similar stories that were more recent. This article talks about the 1950s-60s.
