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.

When the Olland.Cycle principle was originally adopted, both
clock~ and electric motors were considered for the power supply.
·In addition to the tendency of clocks to stop at cold tempera-
tures due to freezing or lubricants and unequal expansion or the
parts, the movement or the clockwork in discrete steps limits
the accuracy of sampling. For these reasons, electric motors
are preferred.
The motor now in use has been built to meet the following spe-
cifications:
(a) 6 to 7.5 volt operation.
(b) l RP.M gear train.
(c) 20 to 40 milliamperes drain.
(d) Speed change at low temperature to be no more than 20%.
(e) Constancy or speed during any single revolution not to
deviate by more than 0.3%.
To check the performance or these motors at cole temperatures,
a series or tes'bswas run on the motors now in use with the
average case seen in Figure 32. The loss in RPM was more than

As long as the speed or revolution does not very markedly with-
in a single revolution, the error is not serious. In early
flights made at prolonged cold temperature, erratic performance
