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.

tion of the altitude controls. On three flights (33, 35 and 39) a Fergusem
meteorograph was added to the train to record flight pressure; of 11 balloons
released, only these three were not recovered.
On seven flights the pressure signals reoeind by radiosonde were lost
while the balloon was still rising; Flight 38 was a shrouded neoprene
balloon which burst as 1t became .fullJ and Flight 39 was a polyethylene
balloon which burst at or near its ceiling f'ollowing a very rapid rise.

On the .other two flights (30 and 35) a very short period of level flight
was recorded before the balloon-borne radio transmitter passed out of range.

On Flights 29 through 33 only a fixed ballast leak was used, set for
flows of from 300 to 600 grams per hour. Other fllghtl used automatic
ballast controls. Although these fixed leaks seemed to be sufficient to keep
the balloons aloft, there was no clear evidence as to what amount would be
needed for most efficient operation. The need for a system of ballast
metering was indicated in this series o.f flights.
