# Office Memorandum . UNITED STATES GOVERNMENT TO : DIRECTOR, FBI DATE: October 2, 1950 FROM : SAC, PHILADELPHIA ATTENTION: MR. LEO LAUGHLIN SUBJECT: FLYING DISC REPORTED AT PHILADELPHIA ON 9/26/50 During the late evening hours of September 26,1950, two Philadelphia police officers observed a peculiar phenomenon on Vare Boulevard near 26th Street when they saw a round object about six feet in circumference slowly float down to the ground. The object had the appearance of a parachute and landed in a field, it being so light it did not even depress the weeds in the field. The object was lavender in color, described by the officers as dewy, sort of like soap suds, and evaporating within fifteen or twenty minutes after it landed. When touched by the officers, the substance composing the object disappeared, leaving nothing but a slight sticky substance. This matter was reported to this office by the Philadelphia Police and for that matter, was subsequently carried in the Philadelphia press as "Flying Saucer Just Dissolves". care Mr. LAUGHLIN of the Bureau was telephonically advised of the above by this office and issued instructions that the matter should be referred to Air Force Intelligence for handling and any investigation. Accordingly, Major WATTS of the Philadelphia Office of OSI was telephonically advised of the above and no further action was taken by this office.
