Documents Show U.S. Test of Germs in Public - 1984-12-04

Army agents secretly sprayed passengers at Washington's National Airport and a city bus terminal with harmless bacteria to test how a smallpox epidemic might be started by enemy forces, documents made public today reveal.
The experiments, which may have also included bus terminals in Chicago and San Francisco, were carried out in 1964 and 1965, according to a heavily censored document obtained by the Church of Scientology under the Freedom of Information Act and released today.
