On November 8, 1948, the U.S. Air Force Directorate of Intelligence documented three separate reports on unidentified aerial phenomena, reflecting growing concern within military intelligence about sightings that could not be readily explained through conventional analysis. The first incident involved crews from the 307th Bomb Group who observed an unidentified aircraft on September 5, 1948, off the west coast of Holland at 30,000 feet. The object was initially traveling at normal jet speed on a heading of 120 degrees when it suddenly began leaving smoke and condensation trails, accelerated sharply, and climbed steeply. According to the file, all three observation crews agreed the craft appeared to be single jet-propelled aircraft possibly employing rocket assists and possessed "tremendous reserve power, more than normal cruising speed for jets of the 1947 variety." The object never came within identification range, and its course offered no indication of purpose. The Air Force assigned this sighting an evaluation rating of B-2.

In the same memorandum, intelligence officers expressed alarm at a pattern of recurring "flying saucer" reports being submitted from multiple sources across various locations. One object had reportedly hovered over Neubiberg Air Base for approximately thirty minutes. Rather than dismissing these reports, the Directorate acknowledged they could not be disregarded and required explanation "perhaps slightly beyond the scope of our present intelligence thinking." Officers of the USAFE Directorate raised the matter during a visit to the Swedish Air Intelligence Service, learning that Swedish technical experts and intelligence officials had reached preliminary conclusions that these phenomena represented "the result of a high technical skill which cannot be credited to any presently known culture on earth" and possibly originated from "previously unknown or unidentified technology, possibly outside the earth." The document references a sighting by a Swedish technical expert near a lake where an object allegedly crashed or landed, prompting Swedish naval salvage operations that reportedly discovered a previously uncharted crater on the lake floor. The report states that while accepting such a theory "poses a whole new group of questions," the American intelligence officers were "inclined not to discredit entirely this somewhat spectacular theory, meantime keeping an open mind on the subject." This file is now publicly available as part of the Department of War PURSUE release.
