Michael Riconosciuto, a technician and self-described weapons engineer, became a key witness in the Inslaw affair when he said he had modified the PROMIS case-management software to include a secret "back door" for tracking people.[1]

Inslaw, a software company, accused the U.S. Justice Department of stealing its PROMIS software. In early 1991 Riconosciuto filed an affidavit with the House Judiciary Committee's investigation, saying he had reprogrammed PROMIS with a back door. He also claimed businessman Earl Brian was part of a secret arrangement with Iran linked to the 1980 hostage release.[1]

Within eight days of the affidavit he was arrested on drug charges. He was tried in 1992 and convicted of methamphetamine offences; he said the charges were manufactured. Federal prison records show he was released in 2017.[1][2]

A 1991 article in TC Technical Consultant, later reposted online, reported Riconosciuto's claims that PROMIS had been sold to 88 countries as a kind of Trojan horse, that he had worked on fuel-air explosives tested in Nevada, and that he had learned of Thomas Townsend Brown's suppressed research. The article tied these to "flying disc" technology in its own framing, but did not attribute explicit UFO claims to Riconosciuto.[2]

Special Counsel Nicholas Bua's review of the Inslaw allegations criticised his inconsistent accounts and likened his PROMIS story to fiction woven around real historical facts. Riconosciuto was also a source for journalist Danny Casolaro, found dead in 1991. There is no support for any UFO-related claims attached to him.[1][3]
