The Roswell Report: Fact vs. Fiction in the New Mexico Desert

USAF / The Black Vault · 1995 · 882 pages · text by OCR

The Roswell Report: Fact versus Fiction in the New Mexico Desert was published by Headquarters United States Air Force in 1995. The Black Vault distributes this copy. It reproduces the report by Col. Richard L. Weaver and the synopsis by 1st Lt. James McAndrew, both written after a General Accounting Office inquiry requested by Representative Steven Schiff. The Air Force search found no evidence of an extraterrestrial craft or crew. It concluded that the Roswell debris most likely came from NYU Flight No. 4, a Project MOGUL balloon train.

SUMMARY OF NYU CONSTANT - LEV4L BALLOON FLIGHTS

FLIGHT NUMBER	DATE AND RELEASE TIME	LAUNCHING SITE	BALLOON WEIGHT	DESCRIPTION OF EQUIPMENT	TOTAL WEIGHT ON BALLOON INCLUDING BALLOON	DESCRIPTION OF ALTITUDE CONTROL	BALLOON WEIGHT	FREE LIFT	BALLOON LIFT	RADIOSONDE RECEPTION %	TRACKING %	AIRCRAFT OBSERVATION %	FLIGHT DURATION	OPTIMUM CONSTRUCT	MAXIMUM CONSTANT LAYLERS MSL	RECOVERY LANDING SITE	CRITIQUE
19	10 Sept. 1947 0659 MST	Alamogordo New Mexico	6.3kg	Data gear Ballast release	13.2kg	Automatic Ballast release assembly	2.4kg	2.3kg	15.5kg	100%	Theodolite 100% SCR-658 100%	Used on search for grounded gear	20min.	None	--	100% Alamogordo	Premature activation of burnoff baroswitch, caused by jerking in high surface wind. Hole blown in balloon after ascent of 200 feet. Balloon descended slowly, landing 2 miles away. Excellent demonstration of blowout patch and that only two hour delay switch needed in burnout circuit.
20	10 Sept. 1947 1306 MST	Alamogordo New Mexico	4.1kg	397 mc Radiosonde Banner Ballast assembly	9.0kg	Manual ballast valve Fixed rate of leak 1000 gm/hr	4.7kg	1.5kg	10.5kg	235min.	Theodolite 145min. SCR-658 235min.	Not required date not essential	Over 235min.	30min. +1000'	Max. 56400' Const. 56000'	0%	Successful upwind release (GM type). Successful appendix design shown. Need of automatic ballast valve demonstrated as high fixed rate of ballast leak did not keep ball on floating after reaching ceiling.
21	12 Sept. 1947 0716 MST	Alamogordo New Mexico	4.1kg	Data gear Banner Ballast assembly	12.8kg	Automatic Ballast release assembly	5.0kg	0.2kg	13.0kg	Not provided for	Theodolite 57min.	Not available	About 600min.	No data	Max. 58000' Estimated	100% Mari-esta, Okle, 535mi.	Flight for Watson. No pressure reporting gear due to weight limitations. Very successful flight due to improved low leakage. General Mills balloon, in spite of complete disabling of ballast release on launching. Low initial ascent observed. Descent observed by finder.
22	12 Sept. 1947 0538 MST	Alamogordo New Mexico	4.1kg	Data gear Banner Ballast assembly	12.8kg	Automatic Ballast release assembly	4.8kg	1.1kg	13.9kg	Not provided for	Theodolite 37min. 10%	1 hour Balloon climbed above range of planes	About 382min.	No data	Max. 54000' Estimated	100% Carlsbad, N.M. 105mi.	Flight for Watson. No pressure reporting gear due to weight limitations. Successful flight. Old style balloon had high leakage but was kept in air due to automatic ballast release. Descent observed by finder.
23	12 Sept. 1947 0918 MST	Alamogordo New Mexico	6.0kg	397 mc Radiosonde Banner, ballast assembly	9.8kg	Automatic Ballast release assembly	3.1kg	0.97kg	10.8kg	125min.	Theodolite 125min. SCR-658 125min.	Not required Only L-5 available	Over 125min.	20min. +1000'	Max. 50700' Const. 50000'	0%	Foot ropes of shrouded balloon believed to have tangled, pulling out balloon valve. Uncertain performance. Perhaps the nooprene balloon burst inside of shroud due to friction.
24	13 Sept. 1947 0551 MST	Alamogordo New Mexico	4.1kg	3 mc transmitter, banner, ballast assembly	12.7kg	Automatic Ballast release assembly	3.2kg	1.1kg	13.8kg	394min.	Theodolite 230min.	Middle 2 hours	Over 394min.	122min. +1000'	Max. Unknown Const. 43000'	Graham, Texas 440mi.	Radiosonde modulator defective. Good balloon climbed to its rising ceiling and remained there until transmitter failed.
25	15 Sept. 1947 0607 MST	Alamogordo New Mexico	3.9kg	Data gear Banner	7.3kg	None	None	1.8kg	9.3kg	210min.	Theodolite 73min. SCR-658 210min.	Not required	Over 210min.	20min. +1000'	Max. Unknown Const. 27000'	0%	Cluster of meteorological balloons for Watson. No altitude control or radiosonde provided.
26	15 Sept. 1947 1002 MST	Alamogordo New Mexico	4.2kg	3 mc transmitter, banner, ballast assembly	13.6kg	Automatic Ballast release assembly	5.0kg	0.2kg	13.8kg	508min.	Theodolite 94min.	2 hours	Over 508min.	Unknown	Ozone, Texas 325mi.	Operational flight for NTU transmitter test. Pressure data which was received proved to be incorrect when gear was recovered.
