The Roswell Report: Fact versus Fiction in the New Mexico Desert was published by Headquarters United States Air Force in 1995. The Black Vault distributes this copy. It reproduces the report by Col. Richard L. Weaver and the synopsis by 1st Lt. James McAndrew, both written after a General Accounting Office inquiry requested by Representative Steven Schiff. The Air Force search found no evidence of an extraterrestrial craft or crew. It concluded that the Roswell debris most likely came from NYU Flight No. 4, a Project MOGUL balloon train.

The force due to friction or drag $ F_{D}=C_{D}\frac{r}{2} A D z $ (This assumes that there is no vertical motion of the air in which the balloon system is floating. We shall later consider the case where an atmospheric force is causing vertical motion of the air.) Where:
P = mass density of the air surrounding the balloon system
A = projected area of the balloon on a plane perpendicular to the relative velocity
Dz = vertical velocity of the balloon system (Velocity in the direction of greater altitude is considered positive.)
$ C_{D}= $ a coefficient of drag, dependent on Reynolds number $ N_{R}=\frac{D_{Z}d\rho}{\mu} $ where: $ d $ = diameter of sphere (ft. )
$ \rho $ = mass density of surrounding fluid $ (\frac{1 b.\ sec.^{2}}{f t.^{4}}) $
$ \mu = $ viscosity of surrounding fluid $ (\frac{\mathrm{lb.\ sec.}}{\mathrm{ft.2}}) $
A plot of drag coefficient against Reynolds number for a sphere is shown in Figure 27.
