Thomas Pesnicak was a member of the Professional Air Traffic Controllers Organization (PATCO) and served as president of Local 204 in Leesburg, Virginia. In August of 1981, Pesnicak was fired alongside approximately 11,000 other PATCO members for participating in an illegal strike against the federal government. The Thomas Pesnicak collection consist primarily of photographs, artifacts, and one periodical.

The Marlene and Ronald Palmer PATCO Scrapbooks, 1979-2001, contain two photo albums compiled by Marlene (Marty) Palmer documenting the Professional Air Traffic Controllers Organization (PATCO) strike, including photographs and quotes by her husband and former PATCO member, Ronald Palmer, as well as the Air Traffic Controllers Support Organization (ATCSO) formed by the spouses of PATCO members in 1979.
