Their book, being published in August by Paragon House of New York, is being prepared for a made-for-TV movie. It is the story of the discovery, retrieval, shipping and cover-up of what the authors call the most important scientific discovery of the past thousand years. It is based on dozens of interviews with first- and second-hand civilian and ex-military witnesses to various parts of what is referred to as a very complex series of events. In order to strengthen their case for government knowledge of what they call “the truth behind almost 50 years of UFO sightings,” the authors are seeking out additional, reliable witnesses. It remains their policy to honor requests to keep the names of witnesses private. For more information, contact Don Berliner, 1202 S. Washington St., Alexandria. VA., 22314 (703-548-0405); or Stanton T. Friedman, 79 Pembroke Crescent, Fredericton, New Brunswick E3B 2V1, Canada (506 457-0232). Witnesses are invited to call either author collect or to make arrangements to meet them at any of their stops in New Mexico, which include the cities of Santa Fe, Albuquerque, Las Cruces, Alamogordo and Roswell.] [Illustration: Fig. 9. (_Left_) B.D. “Duke” Gildenberg served as the civilian meteorologist, engineer, and physical science administrator for the Holloman AFB Balloon Branch from 1951–1981. Gildenberg actively participated in thousands of high altitude balloon operations, including the flights that dropped anthropomorphic dummies at off-range locations throughout New Mexico. Gildenberg, the “father” of Air Force scientific ballooning, was instrumental in identifying the many actual Air Force activities now known as the “Roswell Incident.”] [Illustration: Fig. 10. (_Right_) Charles B. Moore, Professor Emeritus of Atmospheric Physics at the New Mexico Institute of Mining and Technology, was the project engineer for New York University under contract to the U.S. Army Air Forces to develop high altitude balloon technology for Project MOGUL. Moore launched the balloon train on June 4, 1947, that when combined with other events, are now known as the “Roswell Incident.”] Since many of the Roswell accounts and allegations were collected by irregular methods and are not specifically documented, the series of events as alleged by UFO theorists has become very complex and requires clarification. Therefore, the following section will briefly examine some of the more confusing elements of the Roswell stories, specifically, the multiple crash sites and complex scenarios, in order to facilitate an objective analysis of actual events. 1.1 The “Crash Sites,” Scenarios, and Research Methods The “Crash Sites”
