Blumenthal was most appreciative for receiving this information and said he would contact the office of Special Investigations of the Air Force for what assistance they might be to him. He said also he would straighten out Rhodes, informing him the FBI only as a courtesy to the Air Force representatives received the negatives from him and transmitted them. It has been reported that Drew Pearson, on his television program of June 8, 1952, demonstrated photographs of flying discs. It is not known whether the photographs displayed by Pearson on his television program are those referred to in the captioned case. ## RECOMMENDATION In order to bring our file in this matter to an up-to-date status and to resolve the question raised by the subject, it is recommended liaison contact OSI and determine whether the photographs displayed by Pearson on his television program of June 8, 1952, are the photographs obtained from the subject in this case. Inasmuch as Blumenthal indicated he would contact the OSI concerning this matter it is believed highly probable that is where the photographs of flying discs were obtained by Pearson's office.
