Intelligence and Espionage

Several years ago, the National Security Archive initiated a project to obtain critical declassified documentation on key aspects of the U.S.-China relationship, focusing on the period from 1969 to the present. Through Freedom of Information Act requests, collection of relevant publications, and archival research, the Archive has amassed a collection of more than 2,000 documents, consisting of over 15,000 pages, covering major foreign policy issues, U.S.-China security cooperation, technology transfer, economic issues, and intelligence.

Washington, D.C., April 14, 1999 – The use of overhead platforms to observe events on the earth can be traced to the French Revolution, when France organized a company of aerostiers, or balloonists, in April 1794. The United States employed balloons during the Civil War, although little intelligence of value was obtained. In January 1911, the San Diego waterfront became the first target of cameras carried aboard an airplane. Later that year the U.S. Army Signal Corps put aerial photography into the curriculum at its flight training school.
