CIA and UFOs in Chicago

Summary

In 1953, Dr. Leon Davidson published an article on the CIA's involvement in UFO investigations. The document mentions a visit to the CIA office in Chicago, where a soundproofed conference room in a courthouse was used. Davidson did not withhold information at the CIA's request, but because he didn't remember it well enough. The CIA advised him not to use official letterhead without clearance. The location of the Chicago office wasn't discussed, and the article aimed to appeal to magazine readers. The correspondence shows an effort to control the information shared.
