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.

If a balloon is teardrop in shape rather than spherical, the curve would be modified so that the value of c0 , for a given Reynolds number would be lower. In this case the sudden drop in C0 as Reynolds number increases (the change from viscous to turbulent flow) would occur at a lower Reynolds number. We have thus far in our discussion assumed that there is no verti- cal motion of the air surrounding the balloon system relative to the coordinate ! • However, this is not necessarily the case under actual conditions. In many instances vertical llir movement is found in the a bnosphere. Therefore, we must introduce a term to allow for this vertical air movement. In equation (2) this term was indicated as :tFA , the external atmospheric force. We may consider this vertical air movEment· in terms of a velocity Dt. Then the vertical velocity of the balloon system relative to the air surrounding the system will be the difference between the velo- city of the balloon relative to the absolute altitude Dt and the velocity of the surrounding air relative to the absolute altitude This may be equated as D~- 0 C , where Di and DC are both con- sidered positive in the direction of increase of altitude. The total force due to the drag, or friction will be: FD + FATM: CD:. A ( 0!- oc>2 where the00otations are those used previously, exc.ept that now NR = (Oz- :71 de • The relationship between NR and Co will be those used previously. The force due to buoyancy of the lifting gas F8 = Vb (P0 - Pg) where: vb: balloon volume (ft.3) density of the air and lifting gas, respectively (lb./ft.3) This term my also be stated as: where: P0 , Pg = pressure R0 ,Rg = specific F of air and lifting gas gas constant of air and lifting Ta, Tg : temperature of air and lifting gas gas The changes that will take place in this expression are those due to a temperature difference between the lifting gas and the free air, change in volume of the balloon due to loss of lifting gas, change of the gas· constant of the lifting gas due to dilution with air, and (in the case of a balloon that will hold an internal pressure) pressure difference between lifting gas and surrounding air. -68-
