By MARTHA MENDOZA ALBUQUERQUE, N.M. (AP) - A new Air Force report concludes that the ``alien bodies'' that were supposedly covered up along with the crash of a flying saucer in Roswell in 1947 were actually crash-test dummies used in parachute experiments, a UFO skeptic says. Air Force spokeswoman Gloria Cales said Friday that a follow-up report to the 1994 debunking of the so-called Roswell Incident will be released Tuesday, but she refused to discuss details. However, a publisher of the Skeptics UFO Newsletter said he has seen the report and it concludes that dummies used in high-altitude parachute tests in the late 1950s were the basis of reports of alien bodies. ``The theory is that some of these reports of alien bodies might have been mistaken memories of some experiments that the Air Force conducted in New Mexico in the late 1950s, 10 years later, using dummies to test high-altitude parachutes,'' said Philip Klass, publisher of the Skeptics UFO Newsletter in Washington. Klass said he has spoken at length with the report's author, Air Force historian Capt. James McAndrew. McAndrew refused to comment. UFO believers dismissed the report's suggestions. ``I'm sure I saw those aliens,'' said Frank Kaufmann, 80, a retired government intelligence agent. He and several military colleagues were sent to investigate a falling fireball and found a crashed spaceship and five dead aliens in July 1947, he said. ``One was thrown out, it was up against the arroyo, one was half-in, half-out, and the other three were inside,'' Kaufmann said. Deon Crosby, director of the International UFO Museum and Research Center in Roswell, said the explanation is an ``insult to humankind.'' People don't confuse decades, she said. Kaufmann said the bodies were hairless, with ash-colored skin, and were no taller than 5-foot-4. The Air Force report said the dummies ranged between 5-3 and 6-6. ``If you want to keep costs down, would you go to the trouble of having eyebrows and wigs put on the dummies?'' Klass said. The Air Force's 1994 report concluded that the alleged flying saucer debris was the remains of top-secret high-altitude balloons. News of the new report comes two weeks before the 50th anniversary celebration in Roswell, which is expected to attract thousands of visitors. The theory that an alien spaceship crashed there has drawn widespread attention and figured, among other things, in the hit movie ``Independence Day.''
