under heading ON LACK OF DANGER, the panel unanimously finds no direct threat and discusses World War II "Foo Fighters" and Griggs.] SECRET Security Information -8- [PAGE 19] SECRET Security Information AIR FORCE REPORTING SYSTEM [Text present — not reproduced verbatim: page 9 of the meeting report — concludes that Air Force concern was partly caused by public pressure, that its reporting channel gathers mass low-grade reports that overload communications, and that deemphasis is needed, with educational ideas to follow.] SECRET Security Information -9- [PAGE 20] SECRET Security Information ARTIFACTS OF EXTRATERRESTRIAL ORIGIN [Text present — not reproduced verbatim: page 10 of the meeting report — compares the saucer problem with 1943-44 wartime intelligence on German V-weapons, notes the lack of any recovered hardware from sightings, and begins discussion of extraterrestrial origin with Fournet's presentation.] SECRET Security Information -10- [PAGE 21] SECRET Security Information TREMONTON, UTAH, SIGHTING [Text present — not reproduced verbatim: page 11 of the meeting report — Fournet's cases judged raw reports;

panel says further tests with balloons and ornithologists could identify Tremonton, but explaining every one of the roughly 1,900 reports in 1952 is unjustified, and the burden of proof lies with the sighter.] SECRET Security Information -14- [PAGE 25] SECRET Security Information POTENTIAL RELATED DANGERS GEOGRAPHIC LOCATIONS OF UNEXPLAINED SIGHTINGS [Text present — not reproduced verbatim: page 15 of the meeting report — lists related dangers (misidentifying enemy artifacts, overloaded reporting channels, mass hysteria and psychological warfare) and starts discussing the ATIC map of 1952 unexplained sightings clustered near strategic areas such as Los Alamos.] SECRET Security Information -15- [PAGE 26] SECRET Security Information INSTRUMENTATION TO OBTAIN DATA [Text present — not reproduced verbatim: page 16 of the meeting report — finishes the sighting-cluster discussion with no ready explanation; then judges ATIC's plan for 100 inexpensive stereo cameras and Project Twinkle's results of little value, and discusses amateur astronomer sky patrols.] SECRET Security Information -16- [PAGE 27] SECRET Security Information [Text present — not reproduced verbatim: page 17 of the meeting report — notes that much of the sky is already under astronomical surveillance, with no striking unidentified object known to Page or Hynek, and lists observatories and directors (Harvard/Whipple, Yerkes, Alaska, Ottawa, Palomar, Lick).] SECRET Security Information -17- [PAGE 28] SECRET Security Information RADAR PROBLEM OF MUTUAL INTERFERENCE [Text present — not reproduced verbatim: page 18 of the meeting report — panel rejects a government nationwide optical sky patrol, favors radar-scope cameras, and under RADAR PROBLEM OF MUTUAL INTERFERENCE explains false fast tracks, with Berkner's doppler filter and Alvarez's controlled jitter proposals.] SECRET Security Information -18- [PAGE 29] SECRET Security Information UNEXPLAINED COSMIC RAY PHENOMENA EDUCATIONAL PROGRAM [Text present — not reproduced verbatim: page 19 of the meeting report — finishes the radar-interference proposal; two cosmic ray counter cases (Palomar 1949, Los Alamos 1950-51) are attributed to instrument effects; the educational program is introduced with training and debunking aims.] SECRET Security Information -19- [PAGE 30] SECRET Security Information [Text present — not reproduced verbatim: page 20 of the meeting report — describes training levels for radar operators, pilots and observers, and a debunking aim using television, films and articles to reduce public interest and vulnerability to propaganda; suggests psychologists, naming Hadley Cantril, advise.] SECRET Security Information -20- [PAGE 31] SECRET Security Information [Text present — not reproduced verbatim: page 21 of the meeting report — suggests consultants and media channels for the educational program (psychologists, an advertising expert, a Navy special devices center, film producers, amateur astronomers) and says ATIC would need to be integrated into planning.] SECRET Security Information -21- [PAGE 32] SECRET Security Information [Text present — not reproduced verbatim: page 22 of the meeting report — states ATIC would need some expansion; lists Captain Ruppelt's unofficial staffing proposal (analyst panel, investigators, briefing, liaison, weather and astronomy officers); estimates the program might need one and a half to two years.] SECRET Security Information [page number illegible] [PAGE 33] SECRET Security Information UNOFFICIAL INVESTIGATING GROUPS [Text present — not reproduced verbatim: page 23 of the meeting report — controlled balloon experiments, a small ATIC section for residual cases and training films;
