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.

the equation 2500 ft.3jlb.·mol = ae50b where 50 is the expression
for altitude in thousands of feet. Similarly, at 70,000 feet~
6450 =ae70b, and by solving to eliminate a, we find 2.58 = e Ob
or 20b = .95, and the constant b is equal to .0475. Thus, the
equation may be written:

y was originally defined as the molar volume, equal (for 98% helium)
to:
Balloon Volume x 24.4
Gross Load

From this relationehip, we may solve for

or:

Differentiating with respect to W:
(7) dz _ 21. 052 ft
crw-- w 1b where W is gross load in lb.
We see that the value of the constant a is unimportant here, and
the expression is independent of balloon volume, as long as it
does not var/ with time. Included is the assumption that over a
short period of ti~e buoyancy of lifti~gas does not change.
Thus, we have an expression for A, the altitude sensitivity, which
is valid between 40,000 and 105,000 feet. Similarly, it is possible
to evaluate altitude sensitivity for operation between 0 and 30,000
feet. A in this range is equal to 31,400 ft./lb.

A plot of altitude sensit.ivity against load is shown on page 109
of the "Operations" section (Part II of this technical repo~.
