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.

Flight 55: Released .from Alamogordo. New Mexico, 1907 MST. May 3, 1948
Recovered at J~ortheast. Pennsylvania
On this .flight • barograph was .fl01Vll. and a satisfactory Olland-cycle
pressure modulator~& also used .for over 5 hours to give height data. The
length o.f time o.f signalreception is significant, since the battery box
o.f the transmitter was not insulated, and there was no heat to be gained
.from the sun during this nighttime flight. The .001" polyethylene balloon
was observed descending 22 hours later a.f.ter traveling mo!"e than 1500 miles.
The altitude control used on this flight was an automatic ballast valve.
activated by a minimum-pressure switch. and as evidenced by the barogram
in Figure 20 (12-hour rotation). the balloon maintained its altitude for over

NYU BALLOON PROJECT FLIGHT 55
Barograph Record Of G.M. 20 Ft. Balloon W1th
Automatic Ballast Valve

RECOVERED AT NORTHEAST, PA., 4 MAY, 1948
DURATION 23 HOURS

15 hours before beginning its accelerating descent. On this flight re-
cord, marked oscillations are observed at three points. Despite the presence
of automatic ballast controls which might cause oscillatory motion, these
rises and falls must be attributed to atmospheric disturbances since the
magnitude of the .forces required to produce such accelerations is far
greater than any which could be supplied by the control equipment.
