(3) In September 1993 John Peterson, an acquaintance of Woolsey's, first approached the DCI with a package of heavily sanitized CIA material on UFOs
released to UFOlogist Stanton T. Friedman. Peterson and Friedman wanted to know the reasons for the redactions. Woolsey agreed to look into the
matter. See Richard J. Warshaw, Executive Assistant, note to author, 1 November 1994; Warshaw, note to John H. Wright, Information and Privacy
Coordinator, 31 January 1994; and Wright, memorandum to Executive Secretariat, 2 March 1994. (Except where noted, all citations to CIA records in this

(bright lights trailing US aircraft). Fearing they might be Japanese or German secret weapons, OSS investigated but could find no concrete evidence of
enemy weapons and often filed such reports in the "crackpot" category. The OSS also investigated possible sightings of German V-1 and V-2 rockets
before their operational use during the war. See Jacobs, UFO Controversy, p. 33. The Central Intelligence Group, the predecessor of the CIA, also
monitored reports of "ghost rockets" in Sweden in 1946. See CIG, Intelligence Report, 9 April 1947.

Intelligence. Established in 1948, OSI served as the CIA's focal point for the analysis of foreign scientific and technological developments. In
1980, OSI was merged into the Office of Science and Weapons Research. The Office of Current Intelligence (OCI), established on 15 January 1951 was to
provide all-source current intelligence to the President and the National Security Council.
