✦ AI summary
This 7-page file is a Top Secret bundle from the Directorate of Intelligence, Headquarters USAF (T.S. Control Nos. 2-5300 to 2-5399, November 1948). A cover sheet dated 8 Nov 1948 from AFOIR-CO sends extracts from a USAFE teletype (TT 1524, 4 Nov 1948) for information, noting that item 14 went to CIA, AMC and an armament intelligence branch and item 16 to OIR-SR. The extracts include a note to Gen. Cabell forwarding the European Command's special intelligence reports with a warning that most were passed on as received, and a report that three crews of the 307th Bomb Group saw an unidentified aircraft at 30,000 feet off the Dutch coast on 5 Sep 1948 which left smoke and condensation trails, accelerated and climbed (evaluation B-2). Item 14 is a memorandum about flying saucer reports, including one over Neubiberg Air Base and Swedish intelligence views, and the file reproduces it only as a summary. The remaining extracts concern an interrogation of a Soviet airman on a radar near Kholomia airfield and TU-2 bomber equipment (summary only) and a report that the Soviets ordered missions abroad to buy radar tubes in quantity and a complete radar set (evaluation C-3). The file draws no conclusion about the sightings.

(END OF ITEM) SECRET NW 90307 Docld:34714985 Page 3 [PAGE 4] CONFIDENTIAL USAFE 10 TT 1524 CONFIDENTIAL 4 Nov 1948 From OI OB Following report on unidentified aircraft sighting comes from 307th Bomb Group which participated in operation daggar. Unidentified aircraft was sighted by three crews of the group at 1402Z 5 Sep 48 off west coast of Holland, 5155N/0355E. Altitude of all aircraft was 30,000 feet. When first sighted the unidentified A/C was cruising at a normal jet speed, heading 120 degrees. Soon after first seen, A/C began leaving smoke trails and condensation trails accompanied by sudden acceleration and then climb. Generall agreed by observers that it was a single jet propelled A/C employing probably rocket assists with tremendous reserve power, more than normal curising speed for jets of the 1947 variety. Never within identification range; its course did not indicate its purpose. Our evaluation of the above: B-2. (END OF ITEM) CONFIDENTIAL NW 90307 Docld:34714985 Page 4 [PAGE 5] 2-5317 TOP SECRET T.S.
