ABSTRACT
on november 16, 1946, Vincent J. Schaefer of the General Electric Research Laboratories, flying in a light airplane over western Massachusetts, dropped some pellets of dry ice into a moderately thick bank of clouds and a few minutes later observed streaks of snow coming out of the base of the clouds. Without belaboring the point as to whether or not this snow might just have happened to fall naturally at this particular time, and without giving credit to the rainmaking quackery or pagan ritual practiced by man since the stone age, we can set down this date as the beginning of scientific weather modification.
