Beacon Hill Group Briefing
The Beacon Hill Group, Air Force Technical Advisers, were briefed on 26 March 1952 in Boston. This group, consisting of AF consultants in the fields of electronics, optics, acoustics, data collation and other fields, was briefed so that they would have an understanding of the problems confronting Project Blue Book and could offer suggestions. After the briefing several hours were spent discussing the project. The main point of the discussion was to arrive at some means of establishing whether or not there is some unusual type of aircraft flying over the United States. (NARA-PBB85-614) *
