Document CIA-UAP-D021 is a four-page CIA record from 1955 cataloged as an analysis of unconventional aircraft sightings. Its opening pages consist of a Top Secret signature record and cover sheet with custody signatures, dates, and referral offices.

The extracted text of the file is dominated by these registry and cover-sheet markings.
