Documents / FOIA release
This FBI file section collects July 1947 Bureau memoranda, teletypes, citizen letters and newspaper clippings about reported flying discs. They cover recovered objects at Twin Falls, Idaho, Shreveport, Louisiana, Black River Falls, Wisconsin, and Laurel, Maryland, many judged to be pranks, plus a Grafton, Wisconsin priest's circular saw blade the Milwaukee office called a hoax. A Dallas teletype reports a disc recovered near Roswell resembling a high altitude weather balloon with radar reflector. Kenneth Arnold's own account of his sighting is also included.

## } On the night in question the sky was overcast and the objects could not be seen closely; however, they were distinct enough so that all persons could observe what they described as a glow going through the air. They said that the objects appeared to be lighted from the inside and were of a color similar to regular electric lights. None of the persons interviewed noticed any flames or anything except the glow of lights. None of the persons who claimed to have seen these objects were drinking at the time. No other persons in Twin Falls reported seeing the objects mentioned herein; however, Mr. and Mr. stated that it was purely by accident that they had seen the objects and that they would not have seen them unless they were looking for them, because of the speed at which they traveled. On account of the overcast sky they were unable to estimate the size of the objects or the height at which they flew. Detective and Mr. both stated that they could not be meteors or comets, that they flew on a level line and did not appear to drop. They flew at a terrific rate of speed and were visible for only a few minutes at a time. Both persons interviewed said that the objects could not have been geese or ducks and that the lights were not a reflection of the city lights on some object or objects. No further investigation is being conducted by the Butte Office, and the case is being closed.
