U.S. Government UFO Document:
“SUBJECT: Report of Unusual Flying Object”

23 February 1952
(Project Blue Book, U.S. Air Force, Washington, D.C.)


The whole document (not written in U.S. Department of Defense document format):
“TO: DCS/Intelligence
          Headquarters Tactical Air Command
          Langley Air Force Base, Virginia

Captain George P. Arns, Hq 47th  Bomb Wing, and I were flying a
T-11 aircraft, number 41-27496 from Cleveland, Ohio to Langley 
Air Force Base, Virginia, 11 Feb 51, when an unusual flying object 
was sighted near Pittsburgh, Pennsylvania.

A cold front cloud buildup had been encountered southeast of Pittsburgh that could not be topped or penetrated so we changed our flight plan to land at Greater Pittsburgh Airport.

As we approached Pittsburgh from the South at approximately 5,000 feet, a brilliant lighted object was seen high to the right (1 o’clock high), flying a reciprocal course (approx South) to ours. This sighting occurred between 0300 and 0315 EST. At first we thought an aircraft was on fire because of the brilliance and comet-like appearance and yellow to orange flame coloration of the object. However, as the object approached a 3 o’clock high position, regular, one to two pulsations of the [flame] was noted, which continued until the object passed out of sight. Both of us thought it was a jet because of the speed, however, neither of us have ever seen a pulsating flame emitted from a jet at night. The sighting reminded me of buzz-bombs that I had seen many times in Belgium during the last war. However, the buzz-bomb flame was only  a fraction of the size, and was continuous. The object definitely was in excess of five (5) miles from our position. This estimate was based on the location of the cloud buildup on our right several miles, over which the object flew and disappeared from sight. The cloud buildup was between 12,000 and 15,000 feet high (estimate).

The sky was clear and well illuminated by a bright moon above the clouds, affording continuous unobstructed observation of the object for approximately one minute prior to disappearing from sight.

We landed at Pittsburgh at 0330 hours.

Captain [Arns] is not available to sign this statement because he is presently on leave.

Major, USAF
Doctrine Directorate”

Project Blue Book listed the case as “Unknown.”

3 a.m. EST. USAF Captain George P. Arns, of the 47th Bomb Wing and Major Richard J. Gedeon, while flying a T-11 aircraft from Cleveland, Ohio, to Langley AFB, saw an unusual flying object near Pittsburgh, Pa. The object had a bright comet-like appearance of yellow to orange colored flame. It was flying above the plane on a reciprocal course and as it approached one to two second pulsations of the flame were noted. These pulsations continued until the object passed out of sight. The sky was clear and illuminated by a bright moon which afforded continuous observation of the object for approximately one minute prior to disappearing from sight.” presents U.S. government (Project Blue Book, U.S. Air Force) documents that pertain to the UFO case.
