DOW-UAP-PR160, Presentation by Captain Edward J. Ruppelt, 1952
1952年3月26日にボストンで米空軍のエドワード・J・ルッペルト大尉が、再編されたUFO調査の方針を説明した講演の録音(約1時間5分)です。ルッペルトは、空軍が検討した過去の事例約800件のうち約20%が技術分析後も説明できなかったこと、報告がロスアラモス・アルバカーキ・オークリッジなど核関連施設の周辺に集中していたことを述べています。のちにプロジェクト・ブルーブックで使われた回折格子写真やレーダー画面の同期といった手法を紹介しつつ、現象の正体について決定的な証拠はないと強調しています。

This audio file records a March 1952 presentation by Captain Edward J. Ruppelt, outlining the U.S. Air Force’s reorganized investigation into unidentified flying objects (UFOs). The presentation previews prospective technical methodologies, such as diffraction-grating photography and radar-scope synchronization, that were subsequently incorporated into Project Blue Book, a U.S. Air Force program active from 1952 to 1969 that investigated the nature and origin of UFOs. Ruppelt explains that out of approximately 800 historical cases reviewed by the Air Force, approximately 20% remained unexplained after technical analysis. These unresolved reports were sourced from credible military personnel, commercial pilots, and other qualified technical observers. He highlights geographic report concentrations around sensitive national security and nuclear weapons installations (including Los Alamos, Albuquerque, and Oak Ridge National Laboratories) and notes recurring anomalous characteristics, including silent high-speed flight and radar detections indicating unconfirmed air speeds between 1,000 and 3,500 miles per hour. Emphasizing that the Air Force found no conclusive evidence regarding the nature or origin of the phenomena, Ruppelt underscores the national security need for a systematic physical data collection effort to better evaluate these sightings.
