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.

period ot performance to 15 March 1950. A final report "n
development and testing ot constant altitude balloon·systems
was to be submitted to the Air Force. Modification #9 revised
the delivery address for reports.
Modification #10 of 1 May 19$0, increased contract funds to
continue field service and meteorological analysis work to 15
June 1950.
Modification #ll subsequently extended the period of performance
to the termination date ot 31 December 19.$0 and increased funds
accordingly.
B. Constant Altitude Balloon Sptems
Development of a system to maintain balloons at constant al-
titudes tor long periods of time was completed on 1.$ March 1949.
This develo~nt has been completely reported in "Technical
Report 93.02 11 (1) by this Research Division under "Section 1,
General".
Essentially the system as developed at New York University con-
sists of a constant volume balloon of thin polye~lene which,
when filled with hydrogen or heli,m, furnishes the lift for the
system. (Becaus-e ot the increased safety to personnel and equip-
ment, use of helium is to be recommended). The balloon is in-
flated with enot~h gas to balance the weight of the suspended
equipnent, plus a certain amount of "tree lift" which will cause
the system to ascend. When the balloon nears fioating altitude
and becomes full, the gas comprising the "free lift" will be
expelled through an open appendix at the bottom of the balloon.
The system is then at equilibrium at an altitude fixed by the
balloon volume. The ratio of molecular weights of the lifting
gas and air, density ot the surrounding air, and the tot&l balloon
load are as follows:
This state of equilibrium is broken, however, by changes in any
ot the above variables. Basically, losses of lift due to leakage
and diffusion of gas, and changes of temperature of the lifting
gas cause a change from equilibrium conditions.
Any variations causing an increa• in altitude will result merely
in a valving or gas from the fixed volume balloon and a slight
increase in altitude. Changes in the reverse direction, however,
