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.

However:
$$
h = \frac {\Delta p}{d g} \times 1 4 4
$$
where $ \Delta p $ is the pressure difference across the opening (psi) and $ d_{g} $ is density of lifting gas (lb./ft. $ ^{3} $ ). Combining equation (2) and equation (3):
$$
Q \propto \sqrt {\frac {\Delta p}{d _ {g}}}
$$
The pressure difference across any given opening can be evaluated in terms of: height above a known point of zero pressure difference; rate of pressure change with altitude of the atmosphere (which, for any small section of altitude is assumed to be constant); and ratio of the densities of air and the lifting gas. Since the pressure difference across the appendix opening is zero this is our reference point for evaluating height. Figure 23 shows this pressure relationship in graphic form.
