Close questioning revealed they knew nothing of the actual sightings, of their frequency or anything much about them, and therefore cannot be taken seriously. This is characteristic of scientists in general when speaking about subjects which are not in their own immediate field of concern. Chú thích journal cần |journal= (trợ giúp)

  • Erling Strand. “Project Hessdalen 1984 – Final Technical Report”. Truy cập ngày 4 tháng 5 năm 2010. Beside the light measurements, it can be "measured" by radar and laser. Perhaps the measurements we did on the magnetograph and spectrum analyser are due to this phenomenon as well. We have to do more measurements with these instruments, before we can be sure of that.
  • Erling Strand. “Project Hessdalen 1984 – Final Technical Report”. Truy cập ngày 4 tháng 5 năm 2010. We have not found out what this phenomenon is. That could hardly be expected either. But we know that the phenomenon, whatever it is, can be measured.
  • Massimo Teodorani, Gloria Nobili (2002). “EMBLA 2002 – An Optical and Ground Survey in Hessdalen” (PDF). tr. 16. Truy cập ngày 4 tháng 5 năm 2010. Whatever these things are, if some "alien intelligence" is behind the Hessdalen phenomenon, that hypothetical intelligence has shown no interest in searching a direct, continuative and structurally evolved communication with mankind and went on behaving in such a way that the light-phenomenon itself appears to be totally elusive.

  • Edward U.Condon (1968). “Scientific Study of Unidentified Flying Objects”. Truy cập ngày 4 tháng 5 năm 2010. Our general conclusion is that nothing has come from the study of UFOs in the past 21 years that has added to scientific knowledge. Careful consideration of the record as it is available to us leads us to conclude that further extensive study of UFOs probably cannot be justified in the expectation that science will be advanced thereby.

  • Schulgen, George (ngày 28 tháng 10 năm 1947). “Schulgen Memo”. Truy cập ngày 3 tháng 5 năm 2010. the object sighted is being assumed to be a manned aircraft, of Russian origin, and based on the perspective thinking and actual accomplishments of the Germans.
  • “The Air Force Intelligence Report”. Truy cập ngày 3 tháng 5 năm 2010. To implement this policy it was directed that Hq, Air Material Command set up a project with the purpose of collecting, collating, evaluating, and distributing to interested government agencies and contractors, all information concerning sightings and phenomena in the atmosphere which could be construed to be of concern to the national security.
  • United States Air Force (ngày 27 tháng 4 năm 1949). “USAF Briefing Report”. Truy cập ngày 4 tháng 5 năm 2010. The majority of reported incidents have been caused by misidentification of weather balloons, high altitude balloons with lights or electronic equipment, meteors, Bolides, and celestial bodies.
  • United States Air Force (ngày 27 tháng 4 năm 1949). “USAF Briefing Report”. Truy cập ngày 4 tháng 5 năm 2010. There are numerous reports from reliable and competent observers for which a conclusive explanation has not been possible. Some of these involve descriptions which would place them in the category of new manifestations of probable natural phenomena, but others involve configurations and described performance which might conceivably represent an advanced aerodynamical development.
  • Lt. General Nathan F. Twining, USAF. (ngày 23 tháng 9 năm 1947). “AMC Opinion Concerning "Flying Discs". Truy cập ngày 4 tháng 5 năm 2010. The phenomenon is something real and not visionary or fictitious

  • David F. Salisbury (ngày 1 tháng 7 năm 1998). “No evidence of ET: Panel calls for more scientific UFO research”. Stanford Online Report. Truy cập ngày 5 tháng 5 năm 2010. The upshot of this was that, far from supporting Condon's conclusions, I thought the evidence presented in the report suggested that something was going on that needed study.
