This file, from NICAP and CUFOS, collects US Air Force Office of Special Investigations records from 1949 on a Project Grudge special inquiry into a sighting at Rogue River, Oregon, on 24 May 1949. NACA Ames Laboratory employees Gilbert Rivera and Don Heaphy described a silvery pancake-shaped object about 30 feet across that sped off like a jet. An annotated analysis that follows rejects the radar kite explanation and concludes that the case must remain unexplained.

revealed the following information: "On Tuesday, 24 May 1949, at 1700 P.S.T., Mr. B and 4 other persons, while fishing 2 miles upstream (East) of the mouth of the Rogue River, at approximately the same direction and distance from the town of Gold Beach, Oregon, sighted an object which is described as follows: when first sighted it appeared to be a glitter about 4 miles away laterally, at some 5000 feet above the ground which at that point was at sea level or approximately so. The object was then examined through a pair of 8-power Navy type binoculars. Observation time about 90 - 120 seconds. Object appeared round and shiny, something like a fifty-cent piece, viewed from below and to one side. Object's color was silvery and it appeared round in plan view. The object seemed to be solid with no visible openings and was about 30 feet in diameter as nearly as could be judged. Just before Mr. B handed the glasses to Mr. (name deleted - call him Mr. C) the object made a turn on its vertical axis with no tilting or banking and started to move in a southeasterly direction. There was no sign of exhaust or propellor; no driving force could be seen or felt and no sound was heard. The object at no time contacted or came any closer than 5000 feet, approximately, to the earth, and when last seen was disappearing in a southeasterly direction, accelerating to an approximate speed of a jet plane. There were no protuberances other than a slight fin which seemed to start amidship and come back flush with the trailing edge viewed as the ship drifted. No radio antenna or windows, port holes, or any other protuberances, gaps or openings were visible. The only land mark near the sighting point was a rock formation locally known as "Elephant Rock" (underlining by present author), approximately 700 yards N.E. of where the boat in which Mr. B and party were anchored."
On June 24, Agent Brooks also interviewed Mr. C, a mechanic "on a 1 by 3 foot Supersonic Wind Tunnel." at Ames Laboratory. This interview revealed the following information: "On 24 May 1949, at 1700 hours P.S.T., approximately 2 to 2 1/2 miles upstream from the mouth of the Rogue River, Oregon, in a boat anchored approximately midstream, about the same distance East of the town of Gold Beach, Oregon, an object was sighted about 5000 feet above the ground in a direction approximately $60^{\circ}$ reading clockwise from North. Object appeared to be about 1 or 2 miles away. Mr. C. observed the object about 30 seconds with the naked eye at which time he could see only a bright glitter, like a round mirror standing on edge with no apparent motion. Just as the object began to move, Mr. B handed Mr. C a pair of 8-power Navy type binoculars through which Mr. C viewed the object. With the binoculars the object resolved into a pancake-like shape, somewhat thicker in the center than in the edges, perfectly flat on the bottom with a small fin or vane arising about midship and growing gradually higher to the rear ending flush with a trailing edge as the object travelled. Flat surface was parallel to the earth. The object appeared to be made of metal, aluminum or some other shiny metal, and while it appeared oval it could have been perfectly round in plan section. There appeared to be no opening or protuberances of any sort other than the fin already described. Document, cited by the archive. The PDF is mirrored here; the original link is above.
