Operation Sea-Spray

Operation Sea-Spray was a U.S. government experiment conducted in 1950 in San Francisco, California, where researchers released bacteria into the air to study how quickly and widely infectious agents spread in urban environments. The goal was to understand biological warfare and improve defense mechanisms. During the experiment, residents reported unusual symptoms, raising ethical concerns about consent and public safety. The operation highlighted the need for transparency and regulations in government experiments, especially those involving human populations. It remains a controversial example of military testing on civilians without their knowledge.
