|Description||A top secret project to develop nuclear weapons for use in WW2|
Over 100,000 people were involved, though the degree of compartmentalisation was such that "probably no more than a few dozen men in the entire country knew the full meaning of the Manhattan Project, and perhaps only a thousand others even were aware that work on atoms was involved." This invalidates David Grimes' simplistic model of "Conspiracy Theories" at a stroke.
