U.S. Government UFO Document:
“SUBJECT: Aerial Phenomena”

31 May 1950
(Project Blue Book, U.S. Air Force, Washington, D.C.)


The whole document (not written in U.S. Department of Defense document format):
“1. Per request of A. O. Mirarchi, during recent visit to this base, the following information is submitted.

2. Sightings were made on 27 April and 24 May 1950 of aerial phenomena during morning daylight hours at this station. The sightings were made by Land-Air, Inc., personnel while engaged in tracking regular projects with Askania Phototheodolites. It has been reported that objects are sighted in some number; as many as eight have been visible at one time. The individuals making these sightings are professional observers – therefore I would rate their reliaibility [sic] superior. In both cases photos were taken with Askanias.

3. The Holloman AF Base Data Reduction Unit analyzed the 27 April pictures and made a report, a copy of wich I am enclosing with the film for your information. It was believed that triangulation could be effected from pictures taken on 24 May because pictures were taken from two stations. The films were rapidly processed and examined by Data Reduction. However, it was determined that sightings were made on two different objects and triangulation could not be effected. A report from Data Reduction and the films from the sighting are enclosed.

4. There is nothing further to report at this time.”

The cover letter was sent to Commanding Officer, AF Cambridge Research Laboratory, Attn: Base Directorate, Geophysical Research, 230 Albany St., Cambridge, Massachusetts. It is not known who wrote the cover letter, according to Dr. Bruce Maccabee. Quote from Dr. Bruce Maccabee’s paper, NCP-12: The White Sands Proof ( “The writer of this cover letter is not known (no signature). It might have been the Lt. Alpert mentioned below.”

The whole UFO case report:
Brad Sparks:
April 27, 1950. Holloman AFB, Alamogordo, New Mexico (BBU)
While preparing for an MX-776A Shrike air-to-ground missile test Charles Riggs and other members of USAF contractor Land-Air, Inc., Askania theodolite crews saw, tracked, filmed 4 high flying objects on a cinetheodolite at station P-10 and a theodolite at station M-7. Triangulation resulted in 30 ft size and 150,000 ft altitude for the ‘high speed’ objects located between Holloman AFB and Tularosa Peak.

Timothy Good:
Todd Zechel claims that photographic evidence found missing from the Air Force Project Blue Book files eventually found its way to the CIA’s Office of Scientific Intelligence in the 1950s, and specifies a number of movie films taken at White Sands Proving Grounds, New Mexico: a cinetheodolite film taken by a camera tracking station on 27 April 1950; a cinetheodolite film taken by two camera stations on 29 May 1950, allegedly showing two huge UFOs traveling at 2,000 mph; and a 35mm film taken by a military pilot on 14 July 1951.

Brad Sparks:
The Holloman Data Reduction Unit report by mathematician Wilbur Mitchell stated that the speed was high but indeterminable. Evidently they just did not want to state an outlandish number. Presumably they had seconds not minutes of film of high angular velocity objects so a slow-moving Skyhook is ruled out -- also there were 4 objects close enough together that they were all within the FOV, so that also eliminates a single Skyhook (I really doubt that they would not know of Skyhook launches from their own base). Only other possibility is daylight meteors but 150,000 feet (30 miles) is way too low and they should have dropped to earth and burned up not, as what apparently happened, took off in powered flight. (See BB documents below) Oder himself is quoted in the AF documents in 1951 as pushing for Mirarchi's federal prosecution on grounds that Mirarchi had allegedly revealed classified SPEED-ALTITUDE tracking data on UFO’s. That proves that Oder and AFCRL back in 1951 KNEW there was a SUCCESSFUL TRIANGULATION at White Sands, and one so important that they went to the extreme lengths of trying to get Mirarchi thrown in prison in order to maintain the coverup!” presents U.S. government (Project Blue Book, U.S. Air Force) documents that pertain to the UFO case.

I also reported about this UFO case on 24 October 2012.
