Scary stuff! "Open-air tests" is a nice way of putting it.. > Operation Sea-Spray was a 1950 U.S. Navy secret experiment in which Serratia marcescens and Bacillus globigii bacteria were sprayed over the San Francisco Bay Area in California. > From September 20 to 27, 1950, the U.S. Navy released the pathogens off the shore of San Francisco. Based on results from monitoring equipment at 43 locations around the city, the Army determined that San Francisco had received enough of a dose for nearly all of the city's 800,000 residents to inhale millions of particles each day during the week of spraying. > Between 1949 and 1969 open-air tests of biological agents were conducted 239 times.
