Documents / FOIA release
This Central Intelligence Agency briefing from 22 August 1952 presents the Office of Scientific Intelligence review of the Air Force flying saucer investigation, with attachments dated 14 and 19 August. It traces sightings from 1947 and explains most as balloons, aircraft, astronomical bodies or atmospheric effects. About 20% remain unexplained. The briefing rules out US or Soviet weapons and space ships. Its main concerns are psychological warfare, false alerts to air defense, and civilian saucer groups.

complete absence of sound or vapor trail. Evasion upon approach is common.
Radars have shown many unidentified "blips" but there is no reported instance of complete tracking in and out of the maximum drum, and no report of a track from station to station. The blip, in almost every case, passed through the center of the scope.
In combined visual and radar sightings, I might mention as illustrations three specific reports.
First, a visual sighting from a plane over Sandy Hook coincident with a blip seen on a ground radar at Fort Nassau, New Jersey.
Second, a recent Far East report from an aircraft carrier operating between southern Korea and Honshu. Hero ships radar reported a high speed target approaching from the north. Observers on the bridge picked it up visually as a plane. Then still far out, it did a superspeed 160$ ^{\circ}$ turn and shortly thereafter split in two, disappearing both visually and in the PPT scopes.
The third occurred a few days ago at Wright Field and has not yet been fully analysed. Two F-94's with camera guns were vectored in FOIA release, from the cia-readingroom collection.
