GRANTS — A retired Air Force officer says he worked with high tech crash test dummies in the 1950s, and that there's no way they'd be confused with aliens described in rumors arising from the Roswell Incident. Lt. Col. (Ret.) Raymond A. Madson said he isn't buying the latest Air Force explanation of what occurred in Roswell in July 1947. The Pentagon issued a report this week saying the Air Force believes crash test dummies used in the 1950s were mistaken for the rumored 1947 aliens and suggesting that UFO buffs just got their dates mixed up. Madson, 66, who now lives near Grants, said he was project officer for Project High Dive at Holloman Air Force Base for four years starting in the 1950s. He told the Grants newspaper, the Cibola County Beacon, that the Project High Dive dummies were used to test problems pilots might encounter with the ejection mechanisms for bailing out of new generation jet aircraft. Madson said he sent photographs of Project High Dive dummies to the Pentagon for inclusion in the Air Force document issued this week, 'The Roswell Report: Case Closed.' But he said the dummies do not match the descriptions of the very small, almost childlike beings purported to have been seen in 1947 near Roswell. 'They were testing these things (dummies) to try to protect grown men. They would never have used (dummies of) children for such experiments,' he said. Madson also served at Wright Patterson Air Force Base near Dayton, Ohio, before coming to Holloman. His wife worked at Wright Patterson as a secretary in the base medical laboratory, as well, he said. Both of them heard serious talk about little green men who had been brought onto the base and studied secretly, he said. The subject of aliens never came up at Holloman, however, he said. 'I think it was a highly kept secret at that time,' he said. In contrast, there was nothing secret about his dummies, he said. 'The dummies were not covered up or hidden (when transported), and there was no security in the dummy drop phase of the experiments,' he said. And because the windblown dummies might end up falling just about anywhere, the Air Force even offered $25 rewards to local residents around Alamogordo to return the dummies to the base, he said. They were all stamped with labels identifying them as Air Force property, Madson said.
