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.

1n high al ti·tudes# since it freezes below -BOOC and will flow readily at low temperatures. Also# this fluid will absorb only a very slight amount of water which might freeze aloft. Basically three different principles have been used in the control of ballast flow. The first of these is calculated constant flo·•; the second is displacement-switch control; and the third is rate- of-ascent switch control. (1) Constant Flow In the simplest of the control systems, liquid ballast is allowed to flow continuously through an orifice (Figure 8) at a pre- determined rate. This rate is set to slightly exceed the ex- T~~ i 1 .SECTION .A-A \ i ~1tA8CMJC •O$TAI4 B A Figure 8.

If this method is successfully used, the balloon stays full because the gas remaining in it has less load to support. Therefore, the balloon will rise slowly as ballast is dropped, maintaining equilibrium between the buoyancy and the load. In the General Mills 20-foot balloon, for example# diffusion losses are about 200 grams per hour at altitudes near 40,000 feet. The balloon at its ceiling of 40,000 feet with a 26-kilogram pay- load rises about 700 feet with each kilogre.m of ballast dropped. This means that such a balloon using this constant-flow type control will float at a "~ing" which rises at the rate of about 140 feet per ·hour. Constant flow was first obtained by use of the manual ballast valve shown in Figure 9. Due to excessive clogging of this valve, caused by itsannular ring opening, gate -type valves were tested, and finally the use of -17-
