Project Sign (jan 1, 1948 – apr 27, 1949)

Description:

Project Sign or Project Saucer was an official U.S. government study of unidentified flying objects (UFOs) undertaken by the United States Air Force (USAF) and active for most of 1948.

The project was established in 1948 by Air Force General Nathan Farragut Twining, head of the Air Technical Service Command, and was initially named Project SAUCER.[1] The goal of the project was to collect, evaluate, and distribute within the government all information relating to UFO sightings, on the premise that they might represent a national security concern.[1]

On April 27, 1949, the U.S. Air Force publicly released a paper prepared by the Intelligence Division of the Air Materiel Command at Wright-Patterson Field, Ohio.[2] The paper stated that while some UFOs appeared to represent actual aircraft, there was not enough data to determine their origin.[3] Almost all cases were explained by ordinary causes, but the report recommended a continuation of the investigation of all sightings.[1][2]
