Documents / FOIA release
The Roswell Report: Fact versus Fiction in the New Mexico Desert was published in 1995 by Headquarters United States Air Force. It was written in response to Representative Steven H. Schiff's request and a General Accounting Office audit, and it contains Col. Richard L. Weaver's report and 1st Lt. James McAndrew's synopsis, along with attachments, appendices and photographs. The report says researchers found no evidence of an extraterrestrial craft or crew. It concludes that the 1947 debris came from a Project MOGUL balloon train.

PROFESSOR MOORE - 6/8/94 Q: He was unsuccessful? A: He was unsuccessful. Q: What method did he employ? A: Low frequency microphones on the ground. Are you familiar with the Krakatou measurements? Q: No. 19 A: In 1883, Krakatou, near Java, made an enormous explosion and the pressure wave from that went around the world. seven times, and was picked up and ••• There was a report, a big analysis by Lord Railey and others ••• Q: A volcanic eruption? A: Volcanic eruption. Here are the isocomes of the pressure waves from Krakatou as it went out. From the time it took the signal to go out and come back, he went to the antipode which is around Colombia or Venezuela, and came back as a big spherical wave. It went back and forth around the earth. The British investigators were able to show that there was a duct up around the tropopause, and the speed of sound, as I remember, was something like 310 meters per second instead of the regular 334 that we had at sea level. From that they could deduce the temperature of the medium in which the sound was propagating and it was something like minus 25. Q: How was this detected as a pressure wave in that time frame? A: Barograph. Q: What year? A: 1883. This is what prompted Ewing. Q: I'm familiar with barometer-type measurements being used to measure that pressure wave and the fact that it traversed the earth, you said seven times. A: Maurice Ewing had been an oceanographer at Woods Hole and had found a similar acoustic duct in the ocean. You may be familiar with what's called Sofar. In 1945 he wrote a letter to Spaatz suggesting this might be useful in detection of Soviet activity. Q: The 1945 letter was kind of the initiative as a means of detection. A: That's correct. That caused the Army Air Force to begin this research.
