The DOD authorized scientists to spread, “what was thought harmless”, bacteria (Bacillus Globigii ) across US cities and on public transport.
They were trying to simulate a major bioweapons attack on the US.
During one test in 1966, they dropped light bulbs carrying powdered Bacillus Globigii on the New York City subway. They then stalked citizens to measure how the bacteria spread, using a motorized vacuum devise concealed inside a suitcase.
Later research showed that the strain of Bacillus Globigii did pose a risk to people who were already sick or had weak immune systems.
