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.
We see that the maximum allowable (dp/d~la (1-8) tor a 30' diameteJ;
.00111 thick polyethylene balloon is 256XIO-S pSi/ft • Dividing
by (l-B) we have ~he maximum allowable:

= 20.7 x 10-s mb/ft
This is comparable to an altitude of 18,300 ft. or a gross
buoyancy of 450 lb. • the maximum allowable infle.tion of a 30'
diameter • .001" thick polyethylene balloon from the stand-
point of pressure distribution.
In order to determine mathematically the point of failure due
to pressure distribution we may use equations (3) and (5) and
