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 this transmitter operates at a lower frequency, say
1746 kc, the standard aircraft radio compass can be used to
find the direction to the transmitter. No suitable standard
equipment for ground direction-finding has been available to
the project.
c. Receivers and Recorders Used
For the T-49 and T-69 radiosonde transmitters, standard ground-
station equipment was used to receive and record the signal. An
appropriate receiver (National 110 for the T-49 and SCR-658 for the
T-69) feeds the sigpal through a frequency meter and into a Friez
recorder, model AN}Fl~Q-1(). With this system, frequencies between
10 and 200 cycles per second can be recorded.
When the Olland-Cycle pressure moduletor is used, (see Section VI,
A,3) with low-frequency pulses indicating the completion of the pres-
sure or reference circuit, a recorder made by the Brush Development
Co. (Model BL 212) replaces the Friez recorder and frequency meter.
With the AM-1 transmitter, the usual ground receiver has been the
Hammarlund Super-Pro l.:odel SP-400-X. For aircraft operation, an
aircraft radio compass such as AH/.AJall -Y is used.
D. Batteries Used
To extend the life of the batteries used with the T-49 and T-69
transmitters, experimental packs were developed using both dry
and wet cells. A typical ''12-hour" dry-cell pack for the T-69
was composed of:
B supply: 135V--l ea. B90FL (especially assembled for N.Y.U.
by Burgess Battery Co.) or 6 ea. Burgess
XX30 in series--parallel
A supply: 6V--l ea. Burgess 2F4 or 2 ea. F4H in parallel
C bias supPLy: 45V tap of B90FL or XX30 assembly
With an AM-1 transmitter, the input power required is as follows:
"B" supply, 270 volts at about 300 milliamperes; rr~in "A" supply,
li volts at 600 milliemperes; and a separate "A" supply for the
power amplifier, ll volts at 200 millia.mperes. The battery pack
includes 8 Burgess XX45 or Eveready 467 in series--parallela
2 Burgess 4FH batteries in parallel; and one 4FH, respectively.
This pack lasts about 20 hours in fli~ht. Also included in the
battery container were batteries for auxiliary functions such as
Olland-Cycle or program-switch motors, ballast-control relays,
and bring-down mechanisms.
The problem of operating at cold temperature ~~s given much consid-
eration. Special cold temperature batteries were tried with in-
sufficient difference in performance to justify the added expense
and difficulty of procurement. In addition, it was felt that
