# Office Memorandum·UNITED STATES GOVERNMENT TO : SAC, SEATTLE DATE: 8/18/60 FROM : SA MERTON R. ANDERSON SUBJECT: UNIDENTIFIED FLYING OBJECT Sighted 8/12/60 by MURIEL BASS, Spokane,Wash. On 8/18/60 Captain HAROLD REAUME, OSI, Fairchild AFB, Spokane Wash. advised that his office received a telephone call from DOUGLAS BASS, the husband of MURIEL BASS, 1223 E. Celesta, Spokane, and she had informed her husband that she observed an unidentified flying object in the skies over Spokane. REAUME said he personally contacted her and determined the following information: She was in front of her house about 2 or 2:30 P.M. on 8/12/60, and gazing up in the sky she observed a bomber and a fighter plane in the sky. She said she saw an object approach from the southeast which appeared to be traveling straight across at a very fast rate. The object had a slight orange shde, looked like a football, and was almost illuminated. She saw no trail or exhaust fumes, and heard no sound except from the planes. She told REAUME she did not believe the object was "going straight", however it maneuvered slightly, and she lost it from her fiend of vision behind a hill. She said the light was good, the sky was clear and the sun was shining. She told REAUME this was the second sighting for herself of an object of this type, having formerly seen another one at Longview, Washington some six years ago, which was corrborated by others. REAUME stated that he determined MURIEL BASS is 36 years of age, a housewife and nurses aid, and from observation at her residence, the home was clean, and she appeared from her conversation to be well educated. He stated MURIEL BASS is of the negro race. It is noted that an item appeared in today's Spokesman Review of Spokane concerning unidentified flying objects, which appeared to be similar to these described by Mrs. BASS.
