Transcript of a Presentation by Captain Edward J. Ruppelt, 1952

“This document is a transcript of a March 1952 presentation by Captain Edward J. Ruppelt outlining the U.S. Air Force's reorganized investigation into unidentified flying objects (UFOs). ... Ruppelt explains that out of approximately 800 historical cases reviewed by the Air Force, approximately 20% remained unexplained after technical analysis.”

That the Department of War presents this as a transcript of a March 1952 presentation by Ruppelt.

What this page does not support: Anything said in 1952. This paragraph was written in 2026 by the office that released the file. The recording itself begins below it. The date 26 March 1952 and the place, Boston, come from the war.gov listing, not from the transcript.

“Going back, we have approximately 800 cases now on record, and only about 2% of those are actual hoaxes or psychopathological people who just don't know what they see. The misinterpretation of known objects is still, of course, a large factor. I mean, that could possibly account for all of them. However, it's a little bit doubtful. We've gone through these reports and come up with the fact that about 20% are very good reports offered by very reliable people and are just absolutely no conclusions can be drawn.”

The figures given in the briefing: about 800 cases on record, about 2% hoaxes, and about 20% good reports from reliable observers with no conclusion.

“And it should be out. Now, Lieutenant Ruppelt, in getting around on these cases, of course, does a lot of missionary work because when he hits a base, I mean, he briefs them pretty thoroughly on our problem. ... Now, in two weeks, a week from this coming Friday, Life is coming out with an article on these objects, and we've been working closely with Life, and they're supposedly are going to print what we told them to. I hope they do.”

That a speaker at the briefing called him "Lieutenant Ruppelt", and that a speaker said the Air Force had worked closely with Life on a forthcoming article.

What this page does not support: WHO SAID EITHER THING. The transcript marks utterances with bullets and names no speakers; the first bullet speaks about Ruppelt in the third person, so it is not him. Do not attribute the Life remark to Ruppelt. The rank matters too: the title calls him Captain, and this page records someone in the room calling him Lieutenant.
